## Description

## Details

### Macro VIR_COPY_CPUMAP

    #define VIR_COPY_CPUMAP(cpumaps, maplen, vcpu, cpumap);

This macro is to be used in conjunction with virDomainGetVcpus() and virDomainPinVcpu() APIs. VIR_COPY_CPUMAP macro extracts the cpumap of the specified vcpu from cpumaps array and copies it into cpumap to be used later by virDomainPinVcpu() API.

`cpumaps`: | pointer to an array of cpumap (in 8-bit bytes) (IN)
`maplen`: | the length (in bytes) of one cpumap
`vcpu`: | the virtual CPU number
`cpumap`: | pointer to a cpumap (in 8-bit bytes) (OUT) This cpumap must be previously allocated by the caller (ie: malloc(maplen))

### Macro VIR_CPU_MAPLEN

    #define VIR_CPU_MAPLEN(cpu);

This macro is to be used in conjunction with virDomainPinVcpu() API. It returns the length (in bytes) required to store the complete CPU map between a single virtual & all physical CPUs of a domain.

`cpu`: | number of physical CPUs

### Macro VIR_CPU_USABLE

    #define VIR_CPU_USABLE(cpumaps, maplen, vcpu, cpu);

This macro is to be used in conjunction with virDomainGetVcpus() API. VIR_CPU_USABLE macro returns a non-zero value (true) if the cpu is usable by the vcpu, and 0 otherwise.

`cpumaps`: | pointer to an array of cpumap (in 8-bit bytes) (IN)
`maplen`: | the length (in bytes) of one cpumap
`vcpu`: | the virtual CPU number
`cpu`: | the physical CPU number

### Macro VIR_CPU_USED

    #define VIR_CPU_USED(cpumap, cpu);

This macro can be used in conjunction with virNodeGetCPUMap() API. It returns non-zero if the bit of the related CPU is set.

`cpumap`: | pointer to a bit map of real CPUs (in 8-bit bytes) (IN)
`cpu`: | the physical CPU number

### Macro VIR_DOMAIN_BANDWIDTH_IN_AVERAGE

    #define VIR_DOMAIN_BANDWIDTH_IN_AVERAGE;

Macro represents the inbound average of NIC bandwidth, as a uint.

### Macro VIR_DOMAIN_BANDWIDTH_IN_BURST

    #define VIR_DOMAIN_BANDWIDTH_IN_BURST;

Macro represents the inbound burst of NIC bandwidth, as a uint.

### Macro VIR_DOMAIN_BANDWIDTH_IN_FLOOR

    #define VIR_DOMAIN_BANDWIDTH_IN_FLOOR;

Macro represents the inbound floor of NIC bandwidth, as a uint.

### Macro VIR_DOMAIN_BANDWIDTH_IN_PEAK

    #define VIR_DOMAIN_BANDWIDTH_IN_PEAK;

Macro represents the inbound peak of NIC bandwidth, as a uint.

### Macro VIR_DOMAIN_BANDWIDTH_OUT_AVERAGE

    #define VIR_DOMAIN_BANDWIDTH_OUT_AVERAGE;

Macro represents the outbound average of NIC bandwidth, as a uint.

### Macro VIR_DOMAIN_BANDWIDTH_OUT_BURST

    #define VIR_DOMAIN_BANDWIDTH_OUT_BURST;

Macro represents the outbound burst of NIC bandwidth, as a uint.

### Macro VIR_DOMAIN_BANDWIDTH_OUT_PEAK

    					 virFreeCallback freecb)

Adds a callback to receive notifications of domain lifecycle events occurring on a connection. This function requires that an event loop has been previously registered with virEventRegisterImpl() or virEventRegisterDefaultImpl(). Use of this method is no longer recommended. Instead applications should try virConnectDomainEventRegisterAny() which has a more flexible API contract. The virDomainPtr object handle passed into the callback upon delivery of an event is only valid for the duration of execution of the callback. If the callback wishes to keep the domain object after the callback returns, it shall take a reference to it, by calling virDomainRef. The reference can be released once the object is no longer required by calling virDomainFree.

`conn`: | pointer to the connection
`cb`: | callback to the function handling domain events
`opaque`: | opaque data to pass on to the callback
`freecb`: | optional function to deallocate opaque when not used anymore
`Returns`: | 0 on success, -1 on failure. Older versions of some hypervisors sometimes returned a positive number on success, but without any reliable semantics on what that number represents.

### virConnectDomainEventRegisterAny ()

    int	virConnectDomainEventRegisterAny	(virConnectPtr conn,
    						 virDomainPtr dom,
    						 int eventID,
    						 virConnectDomainEventGenericCallback cb,
    						 void * opaque,
    						 virFreeCallback freecb)

Adds a callback to receive notifications of arbitrary domain events occurring on a domain. This function requires that an event loop has been previously registered with virEventRegisterImpl() or virEventRegisterDefaultImpl(). If @dom is NULL, then events will be monitored for any domain. If @dom is non-NULL, then only the specific domain will be monitored. Most types of event have a callback providing a custom set of parameters for the event. When registering an event, it is thus necessary to use the VIR_DOMAIN_EVENT_CALLBACK() macro to cast the supplied function pointer to match the signature of this method. The virDomainPtr object handle passed into the callback upon delivery of an event is only valid for the duration of execution of the callback. If the callback wishes to keep the domain object after the callback returns, it shall take a reference to it, by calling virDomainRef(). The reference can be released once the object is no longer required by calling virDomainFree(). The return value from this method is a positive integer identifier for the callback. To unregister a callback, this callback ID should be passed to the virConnectDomainEventDeregisterAny() method.

`conn`: | pointer to the connection
`dom`: | pointer to the domain
`eventID`: | the event type to receive
`cb`: | callback to the function handling domain events
`opaque`: | opaque data to pass on to the callback
`freecb`: | optional function to deallocate opaque when not used anymore
`Returns`: | a callback identifier on success, -1 on failure.

### virConnectDomainXMLFromNative ()

    char *	virConnectDomainXMLFromNative	(virConnectPtr conn,
    					 const char * nativeFormat,
    					 const char * nativeConfig,
    					 unsigned int flags)

Reads native configuration data describing a domain, and generates libvirt domain XML. The format of the native data is hypervisor dependent.

`conn`: | a connection object
`nativeFormat`: | configuration format importing from
`nativeConfig`: | the configuration data to import
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | a 0 terminated UTF-8 encoded XML instance, or NULL in case of error. The caller must free() the returned value.

### virConnectDomainXMLToNative ()

    char *	virConnectDomainXMLToNative	(virConnectPtr conn,
    					 const char * nativeFormat,
    					 const char * domainXml,
    					 unsigned int flags)

Reads a domain XML configuration document, and generates a native configuration file describing the domain. The format of the native data is hypervisor dependent.

`conn`: | a connection object
`nativeFormat`: | configuration format exporting to
`domainXml`: | the domain configuration to export
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | a 0 terminated UTF-8 encoded native config datafile, or NULL in case of error. The caller must free() the returned value.

### virConnectGetAllDomainStats ()

    int	virConnectGetAllDomainStats	(virConnectPtr conn,
    					 unsigned int stats,
    					 virDomainStatsRecordPtr ** retStats,
    					 unsigned int flags)

Query statistics for all domains on a given connection. Report statistics of various parameters for a running VM according to @stats field. The statistics are returned as an array of structures for each queried domain. The structure contains an array of typed parameters containing the individual statistics. The typed parameter name for each statistic field consists of a dot-separated string containing name of the requested group followed by a group specific description of the statistic value. The statistic groups are enabled using the @stats parameter which is a binary-OR of enum virDomainStatsTypes. The following groups are available (although not necessarily implemented for each hypervisor): VIR_DOMAIN_STATS_STATE: Return domain state and reason for entering that state. The typed parameter keys are in this format: "state.state" - state of the VM, returned as int from virDomainState enum "state.reason" - reason for entering given state, returned as int from virDomain*Reason enum corresponding to given state. VIR_DOMAIN_STATS_CPU_TOTAL: Return CPU statistics and usage information. The typed parameter keys are in this format: "cpu.time" - total cpu time spent for this domain in nanoseconds as unsigned long long. "cpu.user" - user cpu time spent in nanoseconds as unsigned long long. "cpu.system" - system cpu time spent in nanoseconds as unsigned long long. "cpu.cache.monitor.count" - the number of cache monitors for this domain "cpu.cache.monitor.<num>.name" - the name of cache monitor <num> "cpu.cache.monitor.<num>.vcpus" - vcpu list of cache monitor <num> "cpu.cache.monitor.<num>.bank.count" - the number of cache banks in cache monitor <num> "cpu.cache.monitor.<num>.bank.<index>.id" - host allocated cache id for bank <index> in cache monitor <num> "cpu.cache.monitor.<num>.bank.<index>.bytes" - the number of bytes of last level cache that the domain is using on cache bank <index> VIR_DOMAIN_STATS_BALLOON: Return memory balloon device information. The typed parameter keys are in this format: "balloon.current" - the memory in kiB currently used as unsigned long long. "balloon.maximum" - the maximum memory in kiB allowed as unsigned long long. VIR_DOMAIN_STATS_VCPU: Return virtual CPU statistics. Due to VCPU hotplug, the vcpu.<num>.* array could be sparse. The actual size of the array corresponds to "vcpu.current". The array size will never exceed "vcpu.maximum". The typed parameter keys are in this format: "vcpu.current" - current number of online virtual CPUs as unsigned int. "vcpu.maximum" - maximum number of online virtual CPUs as unsigned int. "vcpu.<num>.state" - state of the virtual CPU <num>, as int from virVcpuState enum. "vcpu.<num>.time" - virtual cpu time spent by virtual CPU <num> as unsigned long long. VIR_DOMAIN_STATS_INTERFACE: Return network interface statistics (from domain point of view). The typed parameter keys are in this format: "net.count" - number of network interfaces on this domain as unsigned int. "net.<num>.name" - name of the interface <num> as string. "net.<num>.rx.bytes" - bytes received as unsigned long long. "net.<num>.rx.pkts" - packets received as unsigned long long. "net.<num>.rx.errs" - receive errors as unsigned long long. "net.<num>.rx.drop" - receive packets dropped as unsigned long long. "net.<num>.tx.bytes" - bytes transmitted as unsigned long long. "net.<num>.tx.pkts" - packets transmitted as unsigned long long. "net.<num>.tx.errs" - transmission errors as unsigned long long. "net.<num>.tx.drop" - transmit packets dropped as unsigned long long. VIR_DOMAIN_STATS_BLOCK: Return block devices statistics. By default, this information is limited to the active layer of each <disk> of the domain (where block.count is equal to the number of disks), but adding VIR_CONNECT_GET_ALL_DOMAINS_STATS_BACKING to @flags will expand the array to cover backing chains (block.count corresponds to the number of host resources used together to provide the guest disks). The typed parameter keys are in this format: "block.count" - number of block devices in the subsequent list, as unsigned int. "block.<num>.name" - name of the block device <num> as string. matches the target name (vda/sda/hda) of the block device. If the backing chain is listed, this name is the same for all host resources tied to the same guest device. "block.<num>.backingIndex" - unsigned int giving the <backingStore> index, only used when backing images are listed. "block.<num>.path" - string describing the source of block device <num>, if it is a file or block device (omitted for network sources and drives with no media inserted).

"block.<num>.capacity" - logical size in bytes of the block device backing image as unsigned long long. "block.<num>.physical" - physical size in bytes of the container of the backing image as unsigned long long. "block.<num>.threshold" - current threshold for delivering the VIR_DOMAIN_EVENT_ID_BLOCK_THRESHOLD event in bytes. See virDomainSetBlockThreshold. VIR_DOMAIN_STATS_PERF: Return perf event statistics. The typed parameter keys are in this format: "perf.cmt" - the usage of l3 cache (bytes) by applications running on the platform as unsigned long long. It is produced by cmt perf event. "perf.mbmt" - the total system bandwidth (bytes/s) from one level of cache to another as unsigned long long. It is produced by mbmt perf event. "perf.mbml" - the amount of data (bytes/s) sent through the memory controller on the socket as unsigned long long. It is produced by mbml perf event. "perf.cache_misses" - the count of cache misses as unsigned long long. It is produced by cache_misses perf event. "perf.cache_references" - the count of cache hits as unsigned long long. It is produced by cache_references perf event. "perf.instructions" - The count of instructions as unsigned long long. It is produced by instructions perf event. "perf.cpu_cycles" - The count of cpu cycles (total/elapsed) as an unsigned long long. It is produced by cpu_cycles perf event.

"perf.branch_misses" - The count of branch misses as unsigned long long. It is produced by branch_misses perf event. "perf.bus_cycles" - The count of bus cycles as unsigned long long. It is produced by bus_cycles perf event. "perf.stalled_cycles_frontend" - The count of stalled cpu cycles in the frontend of the instruction processor pipeline as unsigned long long. It is produced by stalled_cycles_frontend perf event. "perf.stalled_cycles_backend" - The count of stalled cpu cycles in the backend of the instruction processor pipeline as unsigned long long. It is produced by stalled_cycles_backend perf event. "perf.ref_cpu_cycles" - The count of total cpu cycles not affected by CPU frequency scaling by applications running as unsigned long long. It is produced by the ref_cpu_cycles perf event. "perf.cpu_clock" - The count of cpu clock time as unsigned long long. It is produced by the cpu_clock perf event. "perf.task_clock" - The count of task clock time as unsigned long long. It is produced by the task_clock perf event. "perf.page_faults" - The count of page faults as unsigned long long. It is produced by the page_faults perf event "perf.context_switches" - The count of context switches as unsigned long long. It is produced by the context_switches perf event. "perf.cpu_migrations" - The count of cpu migrations, from one logical processor to another, as unsigned long long. It is produced by the cpu_migrations perf event. "perf.page_faults_min" - The count of minor page faults as unsigned long long. It is produced by the page_faults_min perf event. "perf.page_faults_maj" - The count of major page faults as unsigned long long. It is produced by the page_faults_maj perf event. "perf.alignment_faults" - The count of alignment faults as unsigned long long. It is produced by the alignment_faults perf event "perf.emulation_faults" - The count of emulation faults as unsigned long long. It is produced by the emulation_faults perf event VIR_DOMAIN_STATS_IOTHREAD: Return IOThread statistics if available. IOThread polling is a timing mechanism that allows the hypervisor to generate a longer period of time in which the guest will perform operations on the CPU being used by the IOThread. The higher the value for poll-max-ns the longer the guest will keep the CPU. This may affect other host threads using the CPU. The poll-grow and poll-shrink values allow the hypervisor to generate a mechanism to add or remove polling time within the confines of 0 and poll-max-ns. For QEMU, the poll-grow is multiplied by the polling interval, while poll-shrink is used as a divisor. When not provided, QEMU may double the polling time until poll-max-ns is reached. When poll-shrink is 0 (zero) QEMU may reset the polling interval to 0 until it finds its "sweet spot". Setting poll-grow too large may cause frequent fluctuation of the time; however, this can be tempered by a high poll-shrink to reduce the polling interval. For example, a poll-grow of 3 will triple the polling time which could quickly exceed poll-max-ns; however, a poll-shrink of 10 would cut that polling time more gradually. The typed parameter keys are in this format: "iothread.cnt" - maximum number of IOThreads in the subsequent list as unsigned int. Each IOThread in the list will will use it's iothread_id value as the <id>. There may be fewer <id> entries than the iothread.cnt value if the polling values are not supported. "iothread.<id>.poll-max-ns" - maximum polling time in ns as an unsigned long long. A 0 (zero) means polling is disabled. "iothread.<id>.poll-grow" - polling time factor as an unsigned int. A 0 (zero) indicates to allow the underlying hypervisor to choose how to grow the polling time. "iothread.<id>.poll-shrink" - polling time divisor as an unsigned int. A 0 (zero) indicates to allow the underlying hypervisor to choose how to shrink the polling time. Note that entire stats groups or individual stat fields may be missing from the output in case they are not supported by the given hypervisor, are not applicable for the current state of the guest domain, or their retrieval was not successful. Using 0 for @stats returns all stats groups supported by the given hypervisor. Specifying VIR_CONNECT_GET_ALL_DOMAINS_STATS_ENFORCE_STATS as @flags makes the function return error in case some of the stat types in @stats were not recognized by the daemon. However, even with this flag, a hypervisor may omit individual fields within a known group if the information is not available; as an extreme example, a supported group may produce zero fields for offline domains if the statistics are meaningful only for a running domain. Passing VIR_CONNECT_GET_ALL_DOMAINS_STATS_NOWAIT in @flags means when libvirt is unable to fetch stats for any of the domains (for whatever reason) only a subset of statistics is returned for the domain. That subset being statistics that don't involve querying the underlying hypervisor. Similarly to virConnectListAllDomains, @flags can contain various flags to filter the list of domains to provide stats for. VIR_CONNECT_GET_ALL_DOMAINS_STATS_ACTIVE selects online domains while VIR_CONNECT_GET_ALL_DOMAINS_STATS_INACTIVE selects offline ones. VIR_CONNECT_GET_ALL_DOMAINS_STATS_PERSISTENT and VIR_CONNECT_GET_ALL_DOMAINS_STATS_TRANSIENT allow to filter the list according to their persistence. To filter the list of VMs by domain state @flags can contain VIR_CONNECT_GET_ALL_DOMAINS_STATS_RUNNING, VIR_CONNECT_GET_ALL_DOMAINS_STATS_PAUSED, VIR_CONNECT_GET_ALL_DOMAINS_STATS_SHUTOFF and/or VIR_CONNECT_GET_ALL_DOMAINS_STATS_OTHER for all other states.

`conn`: | pointer to the hypervisor connection
`stats`: | stats to return, binary-OR of virDomainStatsTypes
`retStats`: | Pointer that will be filled with the array of returned stats
`flags`: | extra flags; binary-OR of virConnectGetAllDomainStatsFlags
`Returns`: | the count of returned statistics structures on success, -1 on error. The requested data are returned in the @retStats parameter. The returned array should be freed by the caller. See virDomainStatsRecordListFree.

### virConnectGetDomainCapabilities ()

    char *	virConnectGetDomainCapabilities	(virConnectPtr conn,
    					 const char * emulatorbin,
    					 const char * arch,
    					 const char * machine,
    					 const char * virttype,
    					 unsigned int flags)

Prior creating a domain (for instance via virDomainCreateXML or virDomainDefineXML) it may be suitable to know what the underlying emulator and/or libvirt is capable of. For instance, if host, libvirt and qemu is capable of VFIO passthrough and so on.

`conn`: | pointer to the hypervisor connection
`emulatorbin`: | path to emulator
`arch`: | domain architecture
`machine`: | machine type
`virttype`: | virtualization type
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | NULL in case of error or an XML string defining the capabilities.

### virConnectListAllDomains ()

    int	virConnectListAllDomains	(virConnectPtr conn,
    					 virDomainPtr ** domains,
    					 unsigned int flags)

Collect a possibly-filtered list of all domains, and return an allocated array of information for each. This API solves the race inherent in virConnectListDomains() and virConnectListDefinedDomains(). Normally, all domains are returned; however, @flags can be used to filter the results for a smaller list of targeted domains. The valid flags are divided into groups, where each group contains bits that describe mutually exclusive attributes of a domain, and where all bits within a group describe all possible domains. Some hypervisors might reject explicit bits from a group where the hypervisor cannot make a distinction (for example, not all hypervisors can tell whether domains have snapshots). For a group supported by a given hypervisor, the behavior when no bits of a group are set is identical to the behavior when all bits in that group are set. When setting bits from more than one group, it is possible to select an impossible combination (such as an inactive transient domain), in that case a hypervisor may return either 0 or an error. The first group of @flags is VIR_CONNECT_LIST_DOMAINS_ACTIVE (online domains) and VIR_CONNECT_LIST_DOMAINS_INACTIVE (offline domains). The next group of @flags is VIR_CONNECT_LIST_DOMAINS_PERSISTENT (defined domains) and VIR_CONNECT_LIST_DOMAINS_TRANSIENT (running but not defined). The next group of @flags covers various domain states: VIR_CONNECT_LIST_DOMAINS_RUNNING, VIR_CONNECT_LIST_DOMAINS_PAUSED, VIR_CONNECT_LIST_DOMAINS_SHUTOFF, and a catch-all for all other states (such as crashed, this catch-all covers the possibility of adding new states). The remaining groups cover boolean attributes commonly asked about domains; they include VIR_CONNECT_LIST_DOMAINS_MANAGEDSAVE and VIR_CONNECT_LIST_DOMAINS_NO_MANAGEDSAVE, for filtering based on whether a managed save image exists; VIR_CONNECT_LIST_DOMAINS_AUTOSTART and VIR_CONNECT_LIST_DOMAINS_NO_AUTOSTART, for filtering based on autostart; VIR_CONNECT_LIST_DOMAINS_HAS_SNAPSHOT and VIR_CONNECT_LIST_DOMAINS_NO_SNAPSHOT, for filtering based on whether a domain has snapshots. Example of usage: virDomainPtr *domains; size_t i; int ret; unsigned int flags = VIR_CONNECT_LIST_DOMAINS_RUNNING | VIR_CONNECT_LIST_DOMAINS_PERSISTENT; ret = virConnectListAllDomains(conn, &domains, flags); if (ret < 0) error(); for (i = 0; i < ret; i++) { do_something_with_domain(domains[i]); //here or in a separate loop if needed virDomainFree(domains[i]); } free(domains);

`conn`: | Pointer to the hypervisor connection.
`domains`: | Pointer to a variable to store the array containing domain objects or NULL if the list is not required (just returns number of guests).
`flags`: | bitwise-OR of virConnectListAllDomainsFlags
`Returns`: | the number of domains found or -1 and sets domains to NULL in case of error. On success, the array stored into @domains is guaranteed to have an extra allocated element set to NULL but not included in the return count, to make iteration easier. The caller is responsible for calling virDomainFree() on each array element, then calling free() on @domains.

### virConnectListDefinedDomains ()

    int	virConnectListDefinedDomains	(virConnectPtr conn,
    					 char ** const names,
    					 int maxnames)

list the defined but inactive domains, stores the pointers to the names in @names For active domains, see virConnectListDomains(). For more control over the results, see virConnectListAllDomains().

`conn`: | pointer to the hypervisor connection
`names`: | pointer to an array to store the names
`maxnames`: | size of the array
`Returns`: | the number of names provided in the array or -1 in case of error. Note that this command is inherently racy; a domain can be defined between a call to virConnectNumOfDefinedDomains() and this call; you are only guaranteed that all currently defined domains were listed if the return is less than @maxids. The client must call free() on each returned name.

### virConnectListDomains ()

    int	virConnectListDomains		(virConnectPtr conn,
    					 int * ids,
    					 int maxids)

Collect the list of active domains, and store their IDs in array @ids For inactive domains, see virConnectListDefinedDomains(). For more control over the results, see virConnectListAllDomains().

`conn`: | pointer to the hypervisor connection
`ids`: | array to collect the list of IDs of active domains
`maxids`: | size of @ids
`Returns`: | the number of domains found or -1 in case of error. Note that this command is inherently racy; a domain can be started between a call to virConnectNumOfDomains() and this call; you are only guaranteed that all currently active domains were listed if the return is less than @maxids.

### virConnectNumOfDefinedDomains ()

    int	virConnectNumOfDefinedDomains	(virConnectPtr conn)

Provides the number of defined but inactive domains.

`conn`: | pointer to the hypervisor connection
`Returns`: | the number of domain found or -1 in case of error

### virConnectNumOfDomains ()

    int	virConnectNumOfDomains		(virConnectPtr conn)

Provides the number of active domains.

`conn`: | pointer to the hypervisor connection
`Returns`: | the number of domain found or -1 in case of error

### virDomainAbortJob ()

    int	virDomainAbortJob		(virDomainPtr domain)

Requests that the current background job be aborted at the soonest opportunity. In case the job is a migration in a post-copy mode, virDomainAbortJob will report an error (see virDomainMigrateStartPostCopy for more details).

`domain`: | a domain object
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainAddIOThread ()

    int	virDomainAddIOThread		(virDomainPtr domain,
    					 unsigned int iothread_id,
    					 unsigned int flags)

Dynamically add an IOThread to the domain. It is left up to the underlying virtual hypervisor to determine the valid range for an @iothread_id and determining whether the @iothread_id already exists. Note that this call can fail if the underlying virtualization hypervisor does not support it or if growing the number is arbitrarily limited. This function requires privileged access to the hypervisor. @flags may include VIR_DOMAIN_AFFECT_LIVE or VIR_DOMAIN_AFFECT_CONFIG. Both flags may be set. If VIR_DOMAIN_AFFECT_LIVE is set, the change affects a running domain and may fail if domain is not alive. If VIR_DOMAIN_AFFECT_CONFIG is set, the change affects persistent state, and will fail for transient domains. If neither flag is specified (that is, @flags is VIR_DOMAIN_AFFECT_CURRENT), then an inactive domain modifies persistent setup, while an active domain is hypervisor-dependent on whether just live or both live and persistent state is changed.

`domain`: | a domain object
`iothread_id`: | the specific IOThread ID value to add
`flags`: | bitwise-OR of virDomainModificationImpact
`Returns`: | 0 in case of success, -1 in case of failure.

### virDomainAttachDevice ()

    int	virDomainAttachDevice		(virDomainPtr domain,
    					 const char * xml)

Create a virtual device attachment to backend. This function, having hotplug semantics, is only allowed on an active domain. For compatibility, this method can also be used to change the media in an existing CDROM/Floppy device, however, applications are recommended to use the virDomainUpdateDeviceFlag method instead. Be aware that hotplug changes might not persist across a domain going into S4 state (also known as hibernation) unless you also modify the persistent domain definition.

`domain`: | pointer to domain object
`xml`: | pointer to XML description of one device
`Returns`: | 0 in case of success, -1 in case of failure.

### virDomainAttachDeviceFlags ()

    int	virDomainAttachDeviceFlags	(virDomainPtr domain,
    					 const char * xml,
    					 unsigned int flags)

Attach a virtual device to a domain, using the flags parameter to control how the device is attached. VIR_DOMAIN_AFFECT_CURRENT specifies that the device allocation is made based on current domain state. VIR_DOMAIN_AFFECT_LIVE specifies that the device shall be allocated to the active domain instance only and is not added to the persisted domain configuration. VIR_DOMAIN_AFFECT_CONFIG specifies that the device shall be allocated to the persisted domain configuration only. Note that the target hypervisor must return an error if unable to satisfy flags. E.g. the hypervisor driver will return failure if LIVE is specified but it only supports modifying the persisted device allocation. For compatibility, this method can also be used to change the media in an existing CDROM/Floppy device, however, applications are recommended to use the virDomainUpdateDeviceFlag method instead. Be aware that hotplug changes might not persist across a domain going into S4 state (also known as hibernation) unless you also modify the persistent domain definition.

`domain`: | pointer to domain object
`xml`: | pointer to XML description of one device
`flags`: | bitwise-OR of virDomainDeviceModifyFlags
`Returns`: | 0 in case of success, -1 in case of failure.

### virDomainBlockCommit ()

    int	virDomainBlockCommit		(virDomainPtr dom,
    					 const char * disk,
    					 const char * base,
    					 const char * top,
    					 unsigned long bandwidth,
    					 unsigned int flags)

Commit changes that were made to temporary top-level files within a disk image backing file chain into a lower-level base file. In other words, take all the difference between @base and @top, and update @base to contain that difference; after the commit, any portion of the chain that previously depended on @top will now depend on @base, and all files after @base up to and including @top will now be invalidated. A typical use of this command is to reduce the length of a backing file chain after taking an external disk snapshot. To move data in the opposite direction, see virDomainBlockPull(). This command starts a long-running commit block job, whose status may be tracked by virDomainBlockJobInfo() with a job type of VIR_DOMAIN_BLOCK_JOB_TYPE_COMMIT, and the operation can be aborted with virDomainBlockJobAbort(). When finished, an asynchronous event is raised to indicate the final status, and the job no longer exists. If the job is aborted, it is up to the hypervisor whether starting a new job will resume from the same point, or start over. As a special case, if @top is the active image (or NULL), and @flags includes VIR_DOMAIN_BLOCK_COMMIT_ACTIVE, the block job will have a type of VIR_DOMAIN_BLOCK_JOB_TYPE_ACTIVE_COMMIT, and operates in two phases. In the first phase, the contents are being committed into @base, and the job can only be canceled. The job transitions to the second phase when the block job event with state VIR_DOMAIN_BLOCK_JOB_READY is emitted for the given device. This information is also visible in the live XML as 'ready="yes"' attribute of the corresponding <mirror> element. Once in the second phase, the user must choose whether to cancel the job (keeping @top as the active image, but now containing only the changes since the time the job ended) or to pivot the job (adjusting to @base as the active image, and invalidating @top). Be aware that this command may invalidate files even if it is aborted; the user is cautioned against relying on the contents of invalidated intermediate files such as @top (when @top is not the active image) without manually rebasing those files to use a backing file of a read-only copy of @base prior to the point where the commit operation was started (and such a rebase cannot be safely done until the commit has successfully completed). However, the domain itself will not have any issues; the active layer remains valid throughout the entire commit operation. Some hypervisors may support a shortcut where if @flags contains VIR_DOMAIN_BLOCK_COMMIT_DELETE, then this command will unlink all files that were invalidated, after the commit successfully completes. If @flags contains VIR_DOMAIN_BLOCK_COMMIT_RELATIVE, the name recorded into the overlay of the @top image (if there is such image) as the path to the new backing file will be kept relative to other images. The operation will fail if libvirt can't infer the name. By default, if @base is NULL, the commit target will be the bottom of the backing chain; if @flags contains VIR_DOMAIN_BLOCK_COMMIT_SHALLOW, then the immediate backing file of @top will be used instead. If @top is NULL, the active image at the top of the chain will be used. Some hypervisors place restrictions on how much can be committed, and might fail if @base is not the immediate backing file of @top, or if @top is the active layer in use by a running domain but @flags did not include VIR_DOMAIN_BLOCK_COMMIT_ACTIVE, or if @top is not the top-most file; restrictions may differ for online vs. offline domains. The @disk parameter is either an unambiguous source name of the block device (the <source file='...'/> sub-element, such as "/path/to/image"), or the device target shorthand (the <target dev='...'/> sub-element, such as "vda"). Valid names can be found by calling virDomainGetXMLDesc() and inspecting elements within //domain/devices/disk. The @base and @top parameters can be either paths to files within the backing chain, or the device target shorthand (the <target dev='...'/> sub-element, such as "vda") followed by an index to the backing chain enclosed in square brackets. Backing chain indexes can be found by inspecting //disk//backingStore/@index in the domain XML. Thus, for example, "vda[3]" refers to the backing store with index equal to "3" in the chain of disk "vda". The maximum bandwidth that will be used to do the commit can be specified with the @bandwidth parameter. If set to 0, there is no limit. If @flags includes VIR_DOMAIN_BLOCK_COMMIT_BANDWIDTH_BYTES, @bandwidth is in bytes/second; otherwise, it is in MiB/second. Values larger than 2^52 bytes/sec may be rejected due to overflow considerations based on the word size of both client and server, and values larger than 2^31 bytes/sec may cause overflow problems if later queried by virDomainGetBlockJobInfo() without scaling. Hypervisors may further restrict the range of valid bandwidth values. Some hypervisors do not support this feature and will return an error if bandwidth is not 0; in this case, it might still be possible for a later call to virDomainBlockJobSetSpeed() to succeed. The actual speed can be determined with virDomainGetBlockJobInfo().

### virDomainBlockCopy ()

    int	virDomainBlockCopy		(virDomainPtr dom,
    					 const char * disk,
    					 const char * destxml,
    					 virTypedParameterPtr params,
    					 int nparams,
    					 unsigned int flags)

Copy the guest-visible contents of a disk image to a new file described by @destxml. The destination XML has a top-level element of <disk>, and resembles what is used when hot-plugging a disk via virDomainAttachDevice(), except that only sub-elements related to describing the new host resource are necessary (sub-elements related to the guest view, such as <target>, are ignored). It is strongly recommended to include a <driver type='...'/> format designation for the destination, to avoid the potential of any security problem that might be caused by probing a file for its format. This command starts a long-running copy. By default, the copy will pull the entire source chain into the destination file, but if @flags also contains VIR_DOMAIN_BLOCK_COPY_SHALLOW, then only the top of the source chain will be copied (the source and destination have a common backing file). The format of the destination file is controlled by the <driver> sub-element of the XML. The destination will be created unless the VIR_DOMAIN_BLOCK_COPY_REUSE_EXT flag is present stating that the file was pre-created with the correct format and metadata and sufficient size to hold the copy. In case the VIR_DOMAIN_BLOCK_COPY_SHALLOW flag is used the pre-created file has to exhibit the same guest visible contents as the backing file of the original image. This allows a management app to pre-create files with relative backing file names, rather than the default of absolute backing file names. A copy job has two parts; in the first phase, the source is copied into the destination, and the job can only be canceled by reverting to the source file; progress in this phase can be tracked via the virDomainBlockJobInfo() command, with a job type of VIR_DOMAIN_BLOCK_JOB_TYPE_COPY. The job transitions to the second phase when the block job event with state VIR_DOMAIN_BLOCK_JOB_READY is emitted for the given device. This information is also visible in the live XML as 'ready="yes"' attribute of the corresponding <mirror> element. All further changes are saved to both source and destination. The user must call virDomainBlockJobAbort() to end the mirroring while choosing whether to revert to source or pivot to the destination. An event is issued when the job ends, and depending on the hypervisor, an event may also be issued when the job transitions from pulling to mirroring. If the job is aborted, a new job will have to start over from the beginning of the first phase. Some hypervisors will restrict certain actions, such as virDomainSave() or virDomainDetachDevice(), while a copy job is active; they may also restrict a copy job to transient domains. If @flags contains VIR_DOMAIN_BLOCK_COPY_TRANSIENT_JOB the job will not be recoverable if the VM is turned off while job is active. This flag will remove the restriction of copy jobs to transient domains. Note that this flag is automatically implied if the VM is transient at the time it's started. The @disk parameter is either an unambiguous source name of the block device (the <source file='...'/> sub-element, such as "/path/to/image"), or the device target shorthand (the <target dev='...'/> sub-element, such as "vda"). Valid names can be found by calling virDomainGetXMLDesc() and inspecting elements within //domain/devices/disk. The @params and @nparams arguments can be used to set hypervisor-specific tuning parameters, such as maximum bandwidth or granularity. For a parameter that the hypervisor understands, explicitly specifying 0 behaves the same as omitting the parameter, to use the hypervisor default; however, omitting a parameter is less likely to fail. This command is a superset of the older virDomainBlockRebase() when used with the VIR_DOMAIN_BLOCK_REBASE_COPY flag, and offers better control over the destination format, the ability to copy to a destination that is not a local file, and the possibility of additional tuning parameters.

`dom`: | pointer to domain object
`disk`: | path to the block device, or device shorthand
`destxml`: | XML description of the copy destination
`params`: | Pointer to block copy parameter objects, or NULL
`nparams`: | Number of block copy parameters (this value can be the same or less than the number of parameters supported)
`flags`: | bitwise-OR of virDomainBlockCopyFlags
`Returns`: | 0 if the operation has started, -1 on failure.

### virDomainBlockJobAbort ()

    int	virDomainBlockJobAbort		(virDomainPtr dom,
    					 const char * disk,
    					 unsigned int flags)

Cancel the active block job on the given disk. The @disk parameter is either an unambiguous source name of the block device (the <source file='...'/> sub-element, such as "/path/to/image"), or (since 0.9.5) the device target shorthand (the <target dev='...'/> sub-element, such as "vda"). Valid names can be found by calling virDomainGetXMLDesc() and inspecting elements within //domain/devices/disk. If the current block job for @disk is VIR_DOMAIN_BLOCK_JOB_TYPE_PULL, then by default, this function performs a synchronous operation and the caller may assume that the operation has completed when 0 is returned. However, BlockJob operations may take a long time to cancel, and during this time further domain interactions may be unresponsive. To avoid this problem, pass VIR_DOMAIN_BLOCK_JOB_ABORT_ASYNC in the @flags argument to enable asynchronous behavior, returning as soon as possible. When the job has been canceled, a BlockJob event will be emitted, with status VIR_DOMAIN_BLOCK_JOB_CANCELED (even if the ABORT_ASYNC flag was not used); it is also possible to poll virDomainBlockJobInfo() to see if the job cancellation is still pending. This type of job can be restarted to pick up from where it left off. If the current block job for @disk is VIR_DOMAIN_BLOCK_JOB_TYPE_COPY, then the default is to abort the mirroring and revert to the source disk; likewise, if the current job is VIR_DOMAIN_BLOCK_JOB_TYPE_ACTIVE_COMMIT, the default is to abort without changing the active layer of @disk. Adding @flags of VIR_DOMAIN_BLOCK_JOB_ABORT_PIVOT causes this call to fail with VIR_ERR_BLOCK_COPY_ACTIVE if the copy or commit is not yet ready; otherwise it will swap the disk over to the new active image to end the mirroring or active commit. An event will be issued when the job is ended, and it is possible to use VIR_DOMAIN_BLOCK_JOB_ABORT_ASYNC to control whether this command waits for the completion of the job. Restarting a copy or active commit job requires starting over from the beginning of the first phase.

`dom`: | pointer to domain object
`disk`: | path to the block device, or device shorthand
`flags`: | bitwise-OR of virDomainBlockJobAbortFlags
`Returns`: | -1 in case of failure, 0 when successful.

### virDomainBlockJobSetSpeed ()

    int	virDomainBlockJobSetSpeed	(virDomainPtr dom,
    					 const char * disk,
    					 unsigned long bandwidth,
    					 unsigned int flags)

Set the maximimum allowable bandwidth that a block job may consume. If bandwidth is 0, the limit will revert to the hypervisor default of unlimited. If @flags contains VIR_DOMAIN_BLOCK_JOB_SPEED_BANDWIDTH_BYTES, @bandwidth is in bytes/second; otherwise, it is in MiB/second. Values larger than 2^52 bytes/sec may be rejected due to overflow considerations based on the word size of both client and server, and values larger than 2^31 bytes/sec may cause overflow problems if later queried by virDomainGetBlockJobInfo() without scaling. Hypervisors may further restrict the range of valid bandwidth values. The @disk parameter is either an unambiguous source name of the block device (the <source file='...'/> sub-element, such as "/path/to/image"), or (since 0.9.5) the device target shorthand (the <target dev='...'/> sub-element, such as "vda"). Valid names can be found by calling virDomainGetXMLDesc() and inspecting elements within //domain/devices/disk.

`dom`: | pointer to domain object
`disk`: | path to the block device, or device shorthand
`bandwidth`: | specify bandwidth limit; flags determine the unit
`flags`: | bitwise-OR of virDomainBlockJobSetSpeedFlags
`Returns`: | -1 in case of failure, 0 when successful.

### virDomainBlockPeek ()

    int	virDomainBlockPeek		(virDomainPtr dom,
    					 const char * disk,
    					 unsigned long long offset,
    					 size_t size,
    					 void * buffer,
    					 unsigned int flags)

This function allows you to read the contents of a domain's disk device. Typical uses for this are to determine if the domain has written a Master Boot Record (indicating that the domain has completed installation), or to try to work out the state of the domain's filesystems. (Note that in the local case you might try to open the block device or file directly, but that won't work in the remote case, nor if you don't have sufficient permission. Hence the need for this call). The @disk parameter is either an unambiguous source name of the block device (the <source file='...'/> sub-element, such as "/path/to/image"), or (since 0.9.5) the device target shorthand (the <target dev='...'/> sub-element, such as "vda"). Valid names can be found by calling virDomainGetXMLDesc() and inspecting elements within //domain/devices/disk. 'offset' and 'size' represent an area which must lie entirely within the device or file. 'size' may be 0 to test if the call would succeed. 'buffer' is the return buffer and must be at least 'size' bytes. NB. The remote driver imposes a 64K byte limit on 'size'. For your program to be able to work reliably over a remote connection you should split large requests to <= 65536 bytes. However, with 0.9.13 this RPC limit has been raised to 1M byte. Starting with version 1.0.6 the RPC limit has been raised again. Now large requests up to 16M byte are supported.

`dom`: | pointer to the domain object
`disk`: | path to the block device, or device shorthand
`offset`: | offset within block device
`size`: | size to read
`buffer`: | return buffer (must be at least size bytes)
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | 0 in case of success or -1 in case of failure.

### virDomainBlockPull ()

    int	virDomainBlockPull		(virDomainPtr dom,
    					 const char * disk,
    					 unsigned long bandwidth,
    					 unsigned int flags)

Populate a disk image with data from its backing image. Once all data from its backing image has been pulled, the disk no longer depends on a backing image. This function pulls data for the entire device in the background. Progress of the operation can be checked with virDomainGetBlockJobInfo() and the operation can be aborted with virDomainBlockJobAbort(). When finished, an asynchronous event is raised to indicate the final status. To move data in the opposite direction, see virDomainBlockCommit(). The @disk parameter is either an unambiguous source name of the block device (the <source file='...'/> sub-element, such as "/path/to/image"), or (since 0.9.5) the device target shorthand (the <target dev='...'/> sub-element, such as "vda"). Valid names can be found by calling virDomainGetXMLDesc() and inspecting elements within //domain/devices/disk. The maximum bandwidth that will be used to do the copy can be specified with the @bandwidth parameter. If set to 0, there is no limit. If @flags includes VIR_DOMAIN_BLOCK_PULL_BANDWIDTH_BYTES, @bandwidth is in bytes/second; otherwise, it is in MiB/second. Values larger than 2^52 bytes/sec may be rejected due to overflow considerations based on the word size of both client and server, and values larger than 2^31 bytes/sec may cause overflow problems if later queried by virDomainGetBlockJobInfo() without scaling. Hypervisors may further restrict the range of valid bandwidth values. Some hypervisors do not support this feature and will return an error if bandwidth is not 0; in this case, it might still be possible for a later call to virDomainBlockJobSetSpeed() to succeed. The actual speed can be determined with virDomainGetBlockJobInfo(). This is shorthand for virDomainBlockRebase() with a NULL base.

`dom`: | pointer to domain object
`disk`: | path to the block device, or device shorthand
`bandwidth`: | (optional) specify bandwidth limit; flags determine the unit
`flags`: | bitwise-OR of virDomainBlockPullFlags
`Returns`: | 0 if the operation has started, -1 on failure.

### virDomainBlockRebase ()

    int	virDomainBlockRebase		(virDomainPtr dom,
    					 const char * disk,
    					 const char * base,
    					 unsigned long bandwidth,
    					 unsigned int flags)

Populate a disk image with data from its backing image chain, and setting the backing image to @base, or alternatively copy an entire backing chain to a new file @base. When @flags is 0, this starts a pull, where @base must be the absolute path of one of the backing images further up the chain, or NULL to convert the disk image so that it has no backing image. Once all data from its backing image chain has been pulled, the disk no longer depends on those intermediate backing images. This function pulls data for the entire device in the background. Progress of the operation can be checked with virDomainGetBlockJobInfo() with a job type of VIR_DOMAIN_BLOCK_JOB_TYPE_PULL, and the operation can be aborted with virDomainBlockJobAbort(). When finished, an asynchronous event is raised to indicate the final status, and the job no longer exists. If the job is aborted, a new one can be started later to resume from the same point. If @flags contains VIR_DOMAIN_BLOCK_REBASE_RELATIVE, the name recorded into the active disk as the location for @base will be kept relative. The operation will fail if libvirt can't infer the name. When @flags includes VIR_DOMAIN_BLOCK_REBASE_COPY, this starts a copy, where @base must be the name of a new file to copy the chain to. By default, the copy will pull the entire source chain into the destination file, but if @flags also contains VIR_DOMAIN_BLOCK_REBASE_SHALLOW, then only the top of the source chain will be copied (the source and destination have a common backing file). By default, @base will be created with the same file format as the source, but this can be altered by adding VIR_DOMAIN_BLOCK_REBASE_COPY_RAW to force the copy to be raw (does not make sense with the shallow flag unless the source is also raw), or by using VIR_DOMAIN_BLOCK_REBASE_REUSE_EXT to reuse an existing file which was pre-created with the correct format and metadata and sufficient size to hold the copy. In case the VIR_DOMAIN_BLOCK_REBASE_SHALLOW flag is used the pre-created file has to exhibit the same guest visible contents as the backing file of the original image. This allows a management app to pre-create files with relative backing file names, rather than the default of absolute backing file names; as a security precaution, you should generally only use reuse_ext with the shallow flag and a non-raw destination file. By default, the copy destination will be treated as type='file', but using VIR_DOMAIN_BLOCK_REBASE_COPY_DEV treats the destination as type='block' (affecting how virDomainGetBlockInfo() will report allocation after pivoting). A copy job has two parts; in the first phase, the @bandwidth parameter affects how fast the source is pulled into the destination, and the job can only be canceled by reverting to the source file; progress in this phase can be tracked via the virDomainBlockJobInfo() command, with a job type of VIR_DOMAIN_BLOCK_JOB_TYPE_COPY. The job transitions to the second phase when the job info states cur == end, and remains alive to mirror all further changes to both source and destination. The user must call virDomainBlockJobAbort() to end the mirroring while choosing whether to revert to source or pivot to the destination. An event is issued when the job ends, and depending on the hypervisor, an event may also be issued when the job transitions from pulling to mirroring. If the job is aborted, a new job will have to start over from the beginning of the first phase. Some hypervisors will restrict certain actions, such as virDomainSave() or virDomainDetachDevice(), while a copy job is active; they may also restrict a copy job to transient domains. The @disk parameter is either an unambiguous source name of the block device (the <source file='...'/> sub-element, such as "/path/to/image"), or the device target shorthand (the <target dev='...'/> sub-element, such as "vda"). Valid names can be found by calling virDomainGetXMLDesc() and inspecting elements within //domain/devices/disk. The @base parameter can be either a path to a file within the backing chain, or the device target shorthand (the <target dev='...'/> sub-element, such as "vda") followed by an index to the backing chain enclosed in square brackets. Backing chain indexes can be found by inspecting //disk//backingStore/@index in the domain XML. Thus, for example, "vda[3]" refers to the backing store with index equal to "3" in the chain of disk "vda". The maximum bandwidth that will be used to do the copy can be specified with the @bandwidth parameter. If set to 0, there is no limit. If @flags includes VIR_DOMAIN_BLOCK_REBASE_BANDWIDTH_BYTES, @bandwidth is in bytes/second; otherwise, it is in MiB/second. Values larger than 2^52 bytes/sec may be rejected due to overflow considerations based on the word size of both client and server, and values larger than 2^31 bytes/sec may cause overflow problems if later queried by virDomainGetBlockJobInfo() without scaling. Hypervisors may further restrict the range of valid bandwidth values. Some hypervisors do not support this feature and will return an error if bandwidth is not 0; in this case, it might still be possible for a later call to virDomainBlockJobSetSpeed() to succeed. The actual speed can be determined with virDomainGetBlockJobInfo(). When @base is NULL and @flags is 0, this is identical to virDomainBlockPull(). When @flags contains VIR_DOMAIN_BLOCK_REBASE_COPY, this command is shorthand for virDomainBlockCopy() where the destination XML encodes @base as a <disk type='file'>, @bandwidth is properly scaled and passed as a typed parameter, the shallow and reuse external flags are preserved, and remaining flags control whether the XML encodes a destination format of raw instead of leaving the destination identical to the source format or probed from the reused file.

`dom`: | pointer to domain object
`disk`: | path to the block device, or device shorthand
`base`: | path to backing file to keep, or device shorthand, or NULL for no backing file
`bandwidth`: | (optional) specify bandwidth limit; flags determine the unit
`flags`: | bitwise-OR of virDomainBlockRebaseFlags
`Returns`: | 0 if the operation has started, -1 on failure.

### virDomainBlockResize ()

    int	virDomainBlockResize		(virDomainPtr dom,
    					 const char * disk,
    					 unsigned long long size,
    					 unsigned int flags)

Resize a block device of domain while the domain is running. If @flags is 0, then @size is in kibibytes (blocks of 1024 bytes); since 0.9.11, if @flags includes VIR_DOMAIN_BLOCK_RESIZE_BYTES, @size is in bytes instead. @size is taken directly as the new size. Depending on the file format, the hypervisor may round up to the next alignment boundary. The @disk parameter is either an unambiguous source name of the block device (the <source file='...'/> sub-element, such as "/path/to/image"), or (since 0.9.5) the device target shorthand (the <target dev='...'/> sub-element, such as "vda"). Valid names can be found by calling virDomainGetXMLDesc() and inspecting elements within //domain/devices/disk. Note that this call may fail if the underlying virtualization hypervisor does not support it; this call requires privileged access to the hypervisor.

`dom`: | pointer to the domain object
`disk`: | path to the block image, or shorthand
`size`: | new size of the block image, see below for unit
`flags`: | bitwise-OR of virDomainBlockResizeFlags
`Returns`: | 0 in case of success or -1 in case of failure.

### virDomainBlockStats ()

    int	virDomainBlockStats		(virDomainPtr dom,
    					 const char * disk,
    					 virDomainBlockStatsPtr stats,
    					 size_t size)

This function returns block device (disk) stats for block devices attached to the domain. The @disk parameter is either the device target shorthand (the <target dev='...'/> sub-element, such as "vda"), or (since 0.9.8) an unambiguous source name of the block device (the <source file='...'/> sub-element, such as "/path/to/image"). Valid names can be found by calling virDomainGetXMLDesc() and inspecting elements within //domain/devices/disk. Some drivers might also accept the empty string for the @disk parameter, and then yield summary stats for the entire domain. Domains may have more than one block device. To get stats for each you should make multiple calls to this function. Individual fields within the stats structure may be returned as -1, which indicates that the hypervisor does not support that particular statistic.

`dom`: | pointer to the domain object
`disk`: | path to the block device, or device shorthand
`stats`: | block device stats (returned)
`size`: | size of stats structure
`Returns`: | 0 in case of success or -1 in case of failure.

### virDomainBlockStatsFlags ()

    int	virDomainBlockStatsFlags	(virDomainPtr dom,
    					 const char * disk,
    					 virTypedParameterPtr params,
    					 int * nparams,
    					 unsigned int flags)

This function is to get block stats parameters for block devices attached to the domain. The @disk parameter is either the device target shorthand (the <target dev='...'/> sub-element, such as "vda"), or (since 0.9.8) an unambiguous source name of the block device (the <source file='...'/> sub-element, such as "/path/to/image"). Valid names can be found by calling virDomainGetXMLDesc() and inspecting elements within //domain/devices/disk. Some drivers might also accept the empty string for the @disk parameter, and then yield summary stats for the entire domain. Domains may have more than one block device. To get stats for each you should make multiple calls to this function. On input, @nparams gives the size of the @params array; on output, @nparams gives how many slots were filled with parameter information, which might be less but will not exceed the input value. As a special case, calling with @params as NULL and @nparams as 0 on input will cause @nparams on output to contain the number of parameters supported by the hypervisor. (Note that block devices of different types might support different parameters, so it might be necessary to compute @nparams for each block device). The caller should then allocate @params array, i.e. (sizeof(@virTypedParameter) * @nparams) bytes and call the API again. See virDomainGetMemoryParameters() for more details.

`dom`: | pointer to domain object
`disk`: | path to the block device, or device shorthand
`params`: | pointer to block stats parameter object (return value, allocated by the caller)
`nparams`: | pointer to number of block stats; input and output
`flags`: | bitwise-OR of virTypedParameterFlags
`Returns`: | -1 in case of error, 0 in case of success.

### virDomainCoreDump ()

    int	virDomainCoreDump		(virDomainPtr domain,
    					 const char * to,
    					 unsigned int flags)

This method will dump the core of a domain on a given file for analysis. Note that for remote Xen Daemon the file path will be interpreted in the remote host. Hypervisors may require the user to manually ensure proper permissions on the file named by @to. If @flags includes VIR_DUMP_CRASH, then leave the guest shut off with a crashed state after the dump completes. If @flags includes VIR_DUMP_LIVE, then make the core dump while continuing to allow the guest to run; otherwise, the guest is suspended during the dump. VIR_DUMP_RESET flag forces reset of the guest after dump. The above three flags are mutually exclusive. Additionally, if @flags includes VIR_DUMP_BYPASS_CACHE, then libvirt will attempt to bypass the file system cache while creating the file, or fail if it cannot do so for the given system; this can allow less pressure on file system cache, but also risks slowing saves to NFS. For more control over the output format, see virDomainCoreDumpWithFormat().

`domain`: | a domain object
`to`: | path for the core file
`flags`: | bitwise-OR of virDomainCoreDumpFlags
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainCoreDumpWithFormat ()

    int	virDomainCoreDumpWithFormat	(virDomainPtr domain,
    					 const char * to,
    					 unsigned int dumpformat,
    					 unsigned int flags)

This method will dump the core of a domain on a given file for analysis. Note that for remote Xen Daemon the file path will be interpreted in the remote host. Hypervisors may require the user to manually ensure proper permissions on the file named by @to. @dumpformat controls which format the dump will have; use of VIR_DOMAIN_CORE_DUMP_FORMAT_RAW mirrors what virDomainCoreDump() will perform. Not all hypervisors are able to support all formats. If @flags includes VIR_DUMP_CRASH, then leave the guest shut off with a crashed state after the dump completes. If @flags includes VIR_DUMP_LIVE, then make the core dump while continuing to allow the guest to run; otherwise, the guest is suspended during the dump. VIR_DUMP_RESET flag forces reset of the guest after dump. The above three flags are mutually exclusive. Additionally, if @flags includes VIR_DUMP_BYPASS_CACHE, then libvirt will attempt to bypass the file system cache while creating the file, or fail if it cannot do so for the given system; this can allow less pressure on file system cache, but also risks slowing saves to NFS.

`domain`: | a domain object
`to`: | path for the core file
`dumpformat`: | format of domain memory's dump (one of virDomainCoreDumpFormat enum)
`flags`: | bitwise-OR of virDomainCoreDumpFlags
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainCreate ()

    int	virDomainCreate			(virDomainPtr domain)

Launch a defined domain. If the call succeeds the domain moves from the defined to the running domains pools. The domain will be paused only if restoring from managed state created from a paused domain. For more control, see virDomainCreateWithFlags().

`domain`: | pointer to a defined domain
`Returns`: | 0 in case of success, -1 in case of error

### virDomainCreateLinux ()

    virDomainPtr	virDomainCreateLinux	(virConnectPtr conn,
    					 const char * xmlDesc,
    					 unsigned int flags)

Deprecated after 0.4.6. Renamed to virDomainCreateXML() providing identical functionality. This existing name will be left indefinitely for API compatibility.

`conn`: | pointer to the hypervisor connection
`xmlDesc`: | string containing an XML description of the domain
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | a new domain object or NULL in case of failure

### virDomainCreateWithFiles ()

    int	virDomainCreateWithFiles	(virDomainPtr domain,
    					 unsigned int nfiles,
    					 int * files,
    					 unsigned int flags)

Launch a defined domain. If the call succeeds the domain moves from the defined to the running domains pools. @files provides an array of file descriptors which will be made available to the 'init' process of the guest. The file handles exposed to the guest will be renumbered to start from 3 (ie immediately following stderr). This is only supported for guests which use container based virtualization technology. If the VIR_DOMAIN_START_PAUSED flag is set, or if the guest domain has a managed save image that requested paused state (see virDomainManagedSave()) the guest domain will be started, but its CPUs will remain paused. The CPUs can later be manually started using virDomainResume(). In all other cases, the guest domain will be running. If the VIR_DOMAIN_START_AUTODESTROY flag is set, the guest domain will be automatically destroyed when the virConnectPtr object is finally released. This will also happen if the client application crashes / loses its connection to the libvirtd daemon. Any domains marked for auto destroy will block attempts at migration, save-to-file, or snapshots. If the VIR_DOMAIN_START_BYPASS_CACHE flag is set, and there is a managed save file for this domain (created by virDomainManagedSave()), then libvirt will attempt to bypass the file system cache while restoring the file, or fail if it cannot do so for the given system; this can allow less pressure on file system cache, but also risks slowing loads from NFS. If the VIR_DOMAIN_START_FORCE_BOOT flag is set, then any managed save file for this domain is discarded, and the domain boots from scratch.

`domain`: | pointer to a defined domain
`nfiles`: | number of file descriptors passed
`files`: | list of file descriptors passed
`flags`: | bitwise-OR of supported virDomainCreateFlags
`Returns`: | 0 in case of success, -1 in case of error

### virDomainCreateWithFlags ()

    int	virDomainCreateWithFlags	(virDomainPtr domain,
    					 unsigned int flags)

Launch a defined domain. If the call succeeds the domain moves from the defined to the running domains pools. If the VIR_DOMAIN_START_PAUSED flag is set, or if the guest domain has a managed save image that requested paused state (see virDomainManagedSave()) the guest domain will be started, but its CPUs will remain paused. The CPUs can later be manually started using virDomainResume(). In all other cases, the guest domain will be running. If the VIR_DOMAIN_START_AUTODESTROY flag is set, the guest domain will be automatically destroyed when the virConnectPtr object is finally released. This will also happen if the client application crashes / loses its connection to the libvirtd daemon. Any domains marked for auto destroy will block attempts at migration, save-to-file, or snapshots. If the VIR_DOMAIN_START_BYPASS_CACHE flag is set, and there is a managed save file for this domain (created by virDomainManagedSave()), then libvirt will attempt to bypass the file system cache while restoring the file, or fail if it cannot do so for the given system; this can allow less pressure on file system cache, but also risks slowing loads from NFS. If the VIR_DOMAIN_START_FORCE_BOOT flag is set, then any managed save file for this domain is discarded, and the domain boots from scratch.

`domain`: | pointer to a defined domain
`flags`: | bitwise-OR of supported virDomainCreateFlags
`Returns`: | 0 in case of success, -1 in case of error

### virDomainCreateXML ()

    virDomainPtr	virDomainCreateXML	(virConnectPtr conn,
    					 const char * xmlDesc,
    					 unsigned int flags)

Launch a new guest domain, based on an XML description similar to the one returned by virDomainGetXMLDesc() This function may require privileged access to the hypervisor. The domain is not persistent, so its definition will disappear when it is destroyed, or if the host is restarted (see virDomainDefineXML() to define persistent domains). If the VIR_DOMAIN_START_PAUSED flag is set, the guest domain will be started, but its CPUs will remain paused. The CPUs can later be manually started using virDomainResume. If the VIR_DOMAIN_START_AUTODESTROY flag is set, the guest domain will be automatically destroyed when the virConnectPtr object is finally released. This will also happen if the client application crashes / loses its connection to the libvirtd daemon. Any domains marked for auto destroy will block attempts at migration, save-to-file, or snapshots. virDomainFree should be used to free the resources after the domain object is no longer needed.

`conn`: | pointer to the hypervisor connection
`xmlDesc`: | string containing an XML description of the domain
`flags`: | bitwise-OR of supported virDomainCreateFlags
`Returns`: | a new domain object or NULL in case of failure

### virDomainCreateXMLWithFiles ()

    virDomainPtr	virDomainCreateXMLWithFiles	(virConnectPtr conn,
    						 const char * xmlDesc,
    						 unsigned int nfiles,
    						 int * files,
    						 unsigned int flags)

Launch a new guest domain, based on an XML description similar to the one returned by virDomainGetXMLDesc() This function may require privileged access to the hypervisor. The domain is not persistent, so its definition will disappear when it is destroyed, or if the host is restarted (see virDomainDefineXML() to define persistent domains). @files provides an array of file descriptors which will be made available to the 'init' process of the guest. The file handles exposed to the guest will be renumbered to start from 3 (ie immediately following stderr). This is only supported for guests which use container based virtualization technology. If the VIR_DOMAIN_START_PAUSED flag is set, the guest domain will be started, but its CPUs will remain paused. The CPUs can later be manually started using virDomainResume. If the VIR_DOMAIN_START_AUTODESTROY flag is set, the guest domain will be automatically destroyed when the virConnectPtr object is finally released. This will also happen if the client application crashes / loses its connection to the libvirtd daemon. Any domains marked for auto destroy will block attempts at migration, save-to-file, or snapshots. virDomainFree should be used to free the resources after the domain object is no longer needed.

`conn`: | pointer to the hypervisor connection
`xmlDesc`: | string containing an XML description of the domain
`nfiles`: | number of file descriptors passed
`files`: | list of file descriptors passed
`flags`: | bitwise-OR of supported virDomainCreateFlags
`Returns`: | a new domain object or NULL in case of failure

### virDomainDefineXML ()

    virDomainPtr	virDomainDefineXML	(virConnectPtr conn,
    					 const char * xml)

Define a domain, but does not start it. This definition is persistent, until explicitly undefined with virDomainUndefine(). A previous definition for this domain would be overridden if it already exists. virDomainFree should be used to free the resources after the domain object is no longer needed.

`conn`: | pointer to the hypervisor connection
`xml`: | the XML description for the domain, preferably in UTF-8
`Returns`: | NULL in case of error, a pointer to the domain otherwise

### virDomainDefineXMLFlags ()

    virDomainPtr	virDomainDefineXMLFlags	(virConnectPtr conn,
    					 const char * xml,
    					 unsigned int flags)

Defines a domain, but does not start it. This definition is persistent, until explicitly undefined with virDomainUndefine(). A previous definition for this domain would be overridden if it already exists. virDomainFree should be used to free the resources after the domain object is no longer needed.

`conn`: | pointer to the hypervisor connection
`xml`: | the XML description for the domain, preferably in UTF-8
`flags`: | bitwise OR of the virDomainDefineFlags constants
`Returns`: | NULL in case of error, a pointer to the domain otherwise

### virDomainDelIOThread ()

    int	virDomainDelIOThread		(virDomainPtr domain,
    					 unsigned int iothread_id,
    					 unsigned int flags)

Dynamically delete an IOThread from the domain. The @iothread_id to be deleted must not have a resource associated with it and can be any of the currently valid IOThread ID's. Note that this call can fail if the underlying virtualization hypervisor does not support it or if reducing the number is arbitrarily limited. This function requires privileged access to the hypervisor. @flags may include VIR_DOMAIN_AFFECT_LIVE or VIR_DOMAIN_AFFECT_CONFIG. Both flags may be set. If VIR_DOMAIN_AFFECT_LIVE is set, the change affects a running domain and may fail if domain is not alive. If VIR_DOMAIN_AFFECT_CONFIG is set, the change affects persistent state, and will fail for transient domains. If neither flag is specified (that is, @flags is VIR_DOMAIN_AFFECT_CURRENT), then an inactive domain modifies persistent setup, while an active domain is hypervisor-dependent on whether just live or both live and persistent state is changed.

`domain`: | a domain object
`iothread_id`: | the specific IOThread ID value to delete
`flags`: | bitwise-OR of virDomainModificationImpact
`Returns`: | 0 in case of success, -1 in case of failure.

### virDomainDestroy ()

    int	virDomainDestroy		(virDomainPtr domain)

Destroy the domain object. The running instance is shutdown if not down already and all resources used by it are given back to the hypervisor. This does not free the associated virDomainPtr object. This function may require privileged access. virDomainDestroy first requests that a guest terminate (e.g. SIGTERM), then waits for it to comply. After a reasonable timeout, if the guest still exists, virDomainDestroy will forcefully terminate the guest (e.g. SIGKILL) if necessary (which may produce undesirable results, for example unflushed disk cache in the guest). To avoid this possibility, it's recommended to instead call virDomainDestroyFlags, sending the VIR_DOMAIN_DESTROY_GRACEFUL flag. If the domain is transient and has any snapshot metadata (see virDomainSnapshotNum()), then that metadata will automatically be deleted when the domain quits.

`domain`: | a domain object
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainDestroyFlags ()

    int	virDomainDestroyFlags		(virDomainPtr domain,
    					 unsigned int flags)

Destroy the domain object. The running instance is shutdown if not down already and all resources used by it are given back to the hypervisor. This does not free the associated virDomainPtr object. This function may require privileged access. Calling this function with no @flags set (equal to zero) is equivalent to calling virDomainDestroy, and after a reasonable timeout will forcefully terminate the guest (e.g. SIGKILL) if necessary (which may produce undesirable results, for example unflushed disk cache in the guest). Including VIR_DOMAIN_DESTROY_GRACEFUL in the flags will prevent the forceful termination of the guest, and virDomainDestroyFlags will instead return an error if the guest doesn't terminate by the end of the timeout; at that time, the management application can decide if calling again without VIR_DOMAIN_DESTROY_GRACEFUL is appropriate. Another alternative which may produce cleaner results for the guest's disks is to use virDomainShutdown() instead, but that depends on guest support (some hypervisor/guest combinations may ignore the shutdown request).

`domain`: | a domain object
`flags`: | bitwise-OR of virDomainDestroyFlagsValues
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainDetachDevice ()

    int	virDomainDetachDevice		(virDomainPtr domain,
    					 const char * xml)

This is an equivalent of virDomainDetachDeviceFlags() when called with @flags parameter set to VIR_DOMAIN_AFFECT_LIVE. See virDomainDetachDeviceFlags() for more details.

`domain`: | pointer to domain object
`xml`: | pointer to XML description of one device
`Returns`: | 0 in case of success, -1 in case of failure.

### virDomainDetachDeviceAlias ()

    int	virDomainDetachDeviceAlias	(virDomainPtr domain,
    					 const char * alias,
    					 unsigned int flags)

Detach a virtual device from a domain, using the alias to specify the device. The value of @flags should be either VIR_DOMAIN_AFFECT_CURRENT, or a bitwise-or of values from VIR_DOMAIN_AFFECT_LIVE and VIR_DOMAIN_AFFECT_CURRENT, although hypervisors vary in which flags are supported. In contrast to virDomainDetachDeviceFlags() this API is asynchronous - it returns immediately after sending the detach request to the hypervisor. It's caller's responsibility to wait for VIR_DOMAIN_EVENT_ID_DEVICE_REMOVED event to signal actual device removal or for VIR_DOMAIN_EVENT_ID_DEVICE_REMOVAL_FAILED to signal rejected device removal.

`domain`: | pointer to a domain object
`alias`: | device alias
`flags`: | bitwise-OR of virDomainDeviceModifyFlags
`Returns`: | 0 in case of success, -1 in case of failure.

### virDomainDetachDeviceFlags ()

    int	virDomainDetachDeviceFlags	(virDomainPtr domain,
    					 const char * xml,
    					 unsigned int flags)

Detach a virtual device from a domain, using the flags parameter to control how the device is detached. VIR_DOMAIN_AFFECT_CURRENT specifies that the device allocation is removed based on current domain state. VIR_DOMAIN_AFFECT_LIVE specifies that the device shall be deallocated from the active domain instance only and is not from the persisted domain configuration. VIR_DOMAIN_AFFECT_CONFIG specifies that the device shall be deallocated from the persisted domain configuration only. Note that the target hypervisor must return an error if unable to satisfy flags. E.g. the hypervisor driver will return failure if LIVE is specified but it only supports removing the persisted device allocation. Some hypervisors may prevent this operation if there is a current block job running operation on the device being detached; in that case, use virDomainBlockJobAbort() to stop the block job first. Beware that depending on the hypervisor and device type, detaching a device from a running domain may be asynchronous. That is, calling virDomainDetachDeviceFlags may just request device removal while the device is actually removed later (in cooperation with a guest OS). Previously, this fact was ignored and the device could have been removed from domain configuration before it was actually removed by the hypervisor causing various failures on subsequent operations. To check whether the device was successfully removed, either recheck domain configuration using virDomainGetXMLDesc() or add a handler for the VIR_DOMAIN_EVENT_ID_DEVICE_REMOVED event. In case the device is already gone when virDomainDetachDeviceFlags returns, the event is delivered before this API call ends. To help existing clients work better in most cases, this API will try to transform an asynchronous device removal that finishes shortly after the request into a synchronous removal. In other words, this API may wait a bit for the removal to complete in case it was not synchronous. Be aware that hotplug changes might not persist across a domain going into S4 state (also known as hibernation) unless you also modify the persistent domain definition. The supplied XML description of the device should be as specific as its definition in the domain XML. The set of attributes used to match the device are internal to the drivers. Using a partial definition, or attempting to detach a device that is not present in the domain XML, but shares some specific attributes with one that is present, may lead to unexpected results.

`domain`: | pointer to domain object
`xml`: | pointer to XML description of one device
`flags`: | bitwise-OR of virDomainDeviceModifyFlags
`Returns`: | 0 in case of success, -1 in case of failure.

### virDomainFSFreeze ()

    int	virDomainFSFreeze		(virDomainPtr dom,
    					 const char ** mountpoints,
    					 unsigned int nmountpoints,
    					 unsigned int flags)

Freeze specified filesystems within the guest (hence guest agent may be required depending on hypervisor used). If @mountpoints is NULL and @nmountpoints is 0, every mounted filesystem on the guest is frozen. In some environments (e.g. QEMU guest with guest agent which doesn't support mountpoints argument), @mountpoints may need to be NULL.

`dom`: | a domain object
`mountpoints`: | list of mount points to be frozen
`nmountpoints`: | the number of mount points specified in @mountpoints
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | the number of frozen filesystems on success, -1 otherwise.

### virDomainFSInfoFree ()

    void	virDomainFSInfoFree		(virDomainFSInfoPtr info)

Frees all the memory occupied by @info.

`info`: | pointer to a FSInfo object

### virDomainFSThaw ()

    int	virDomainFSThaw			(virDomainPtr dom,
    					 const char ** mountpoints,
    					 unsigned int nmountpoints,
    					 unsigned int flags)

Thaw specified filesystems within the guest. If @mountpoints is NULL and @nmountpoints is 0, every mounted filesystem on the guest is thawed. In some drivers (e.g. QEMU driver), @mountpoints may need to be NULL.

`dom`: | a domain object
`mountpoints`: | list of mount points to be thawed
`nmountpoints`: | the number of mount points specified in @mountpoints
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | the number of thawed filesystems on success, -1 otherwise.

### virDomainFSTrim ()

    int	virDomainFSTrim			(virDomainPtr dom,
    					 const char * mountPoint,
    					 unsigned long long minimum,
    					 unsigned int flags)

Calls FITRIM within the guest (hence guest agent may be required depending on hypervisor used). Either call it on each mounted filesystem (@mountPoint is NULL) or just on specified @mountPoint. @minimum hints that free ranges smaller than this may be ignored (this is a hint and the guest may not respect it). By increasing this value, the fstrim operation will complete more quickly for filesystems with badly fragmented free space, although not all blocks will be discarded. If @minimum is not zero, the command may fail.

`dom`: | a domain object
`mountPoint`: | which mount point to trim
`minimum`: | Minimum contiguous free range to discard in bytes
`flags`: | extra flags, not used yet, so callers should always pass 0
`Returns`: | 0 on success, -1 otherwise.

### virDomainFree ()

    int	virDomainFree			(virDomainPtr domain)

Free the domain object. The running instance is kept alive. The data structure is freed and should not be used thereafter.

`domain`: | a domain object
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainGetAutostart ()

    int	virDomainGetAutostart		(virDomainPtr domain,
    					 int * autostart)

Provides a boolean value indicating whether the domain configured to be automatically started when the host machine boots. Please note that this might result in unexpected behaviour if used for some session URIs. Since the session daemon is started with --timeout it comes and goes and as it does so it autostarts domains which might have been shut off recently.

`domain`: | a domain object
`autostart`: | the value returned
`Returns`: | -1 in case of error, 0 in case of success

### virDomainGetBlkioParameters ()

    int	virDomainGetBlkioParameters	(virDomainPtr domain,
    					 virTypedParameterPtr params,
    					 int * nparams,
    					 unsigned int flags)

Get all blkio parameters. On input, @nparams gives the size of the @params array; on output, @nparams gives how many slots were filled with parameter information, which might be less but will not exceed the input value. As a special case, calling with @params as NULL and @nparams as 0 on input will cause @nparams on output to contain the number of parameters supported by the hypervisor. The caller should then allocate @params array, i.e. (sizeof(@virTypedParameter) * @nparams) bytes and call the API again. See virDomainGetMemoryParameters() for an equivalent usage example. This function may require privileged access to the hypervisor. This function expects the caller to allocate the @params.

`domain`: | pointer to domain object
`params`: | pointer to blkio parameter object (return value, allocated by the caller)
`nparams`: | pointer to number of blkio parameters; input and output
`flags`: | bitwise-OR of virDomainModificationImpact and virTypedParameterFlags
`Returns`: | -1 in case of error, 0 in case of success.

### virDomainGetBlockInfo ()

    int	virDomainGetBlockInfo		(virDomainPtr domain,
    					 const char * disk,
    					 virDomainBlockInfoPtr info,
    					 unsigned int flags)

Extract information about a domain's block device. The @disk parameter is either an unambiguous source name of the block device (the <source file='...'/> sub-element, such as "/path/to/image"), or (since 0.9.5) the device target shorthand (the <target dev='...'/> sub-element, such as "vda"). Valid names can be found by calling virDomainGetXMLDesc() and inspecting elements within //domain/devices/disk. For QEMU domains, the allocation and physical virDomainBlockInfo values returned will generally be the same, except when using a non raw, block backing device, such as qcow2 for an active domain. When the persistent domain is not active, QEMU will return the default which is the same value for allocation and physical. Active QEMU domains can return an allocation value which is more representative of the currently used blocks by the device compared to the physical size of the device. Applications can use/monitor the allocation value with the understanding that if the domain becomes inactive during an attempt to get the value, the default values will be returned. Thus, the application should check after the call for the domain being inactive if the values are the same. Optionally, the application could be watching for a shutdown event and then ignore any values received afterwards. This can be an issue when a domain is being migrated and the exact timing of the domain being made inactive and check of the allocation value results the default being returned. For a transient domain in the similar situation, this call will return -1 and an error message indicating the "domain is not running". The following is some pseudo code illustrating the call sequence: ... virDomainPtr dom; virDomainBlockInfo info; char *device; ... // Either get a list of all domains or a specific domain // via a virDomainLookupBy*() call. // // It's also required to fill in the device pointer, but that's // specific to the implementation. For the purposes of this example // a qcow2 backed device name string would need to be provided. ... // If the following call is made on a persistent domain with a // qcow2 block backed block device, then it's possible the returned // allocation equals the physical value. In that case, the domain // that may have been active prior to calling has become inactive, // such as is the case during a domain migration. Thus once we // get data returned, check for active domain when the values are // the same. if (virDomainGetBlockInfo(dom, device, &info, 0) < 0) goto failure; if (info.allocation == info.physical) { // If the domain is no longer active, // then the defaults are being returned. if (!virDomainIsActive()) goto ignore_return; } // Do something with the allocation and physical values ...

`domain`: | a domain object
`disk`: | path to the block device, or device shorthand
`info`: | pointer to a virDomainBlockInfo structure allocated by the user
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainGetBlockIoTune ()

    int	virDomainGetBlockIoTune		(virDomainPtr dom,
    					 const char * disk,
    					 virTypedParameterPtr params,
    					 int * nparams,
    					 unsigned int flags)

Get all block IO tunable parameters for a given device. On input, @nparams gives the size of the @params array; on output, @nparams gives how many slots were filled with parameter information, which might be less but will not exceed the input value. As a special case, calling with @params as NULL and @nparams as 0 on input will cause @nparams on output to contain the number of parameters supported by the hypervisor, either for the given @disk (note that block devices of different types might support different parameters), or if @disk is NULL, for all possible disks. The caller should then allocate @params array, i.e. (sizeof(@virTypedParameter) * @nparams) bytes and call the API again. See virDomainGetMemoryParameters() for more details. The @disk parameter is either an unambiguous source name of the block device (the <source file='...'/> sub-element, such as "/path/to/image"), or the device target shorthand (the <target dev='...'/> sub-element, such as "xvda"). Valid names can be found by calling virDomainGetXMLDesc() and inspecting elements within //domain/devices/disk. This parameter cannot be NULL unless @nparams is 0 on input.

`dom`: | pointer to domain object
`disk`: | path to the block device, or device shorthand
`params`: | Pointer to blkio parameter object (return value, allocated by the caller)
`nparams`: | Pointer to number of blkio parameters
`flags`: | bitwise-OR of virDomainModificationImpact and virTypedParameterFlags
`Returns`: | -1 in case of error, 0 in case of success.

### virDomainGetBlockJobInfo ()

    int	virDomainGetBlockJobInfo	(virDomainPtr dom,
    					 const char * disk,
    					 virDomainBlockJobInfoPtr info,
    					 unsigned int flags)

Request block job information for the given disk. If an operation is active @info will be updated with the current progress. The units used for the bandwidth field of @info depends on @flags. If @flags includes VIR_DOMAIN_BLOCK_JOB_INFO_BANDWIDTH_BYTES, bandwidth is in bytes/second (although this mode can risk failure due to overflow, depending on both client and server word size); otherwise, the value is rounded up to MiB/s. The @disk parameter is either an unambiguous source name of the block device (the <source file='...'/> sub-element, such as "/path/to/image"), or (since 0.9.5) the device target shorthand (the <target dev='...'/> sub-element, such as "vda"). Valid names can be found by calling virDomainGetXMLDesc() and inspecting elements within //domain/devices/disk. As a corner case underlying hypervisor may report cur == 0 and end == 0 when the block job hasn't been started yet. In this case libvirt reports cur = 0 and end = 1. However, hypervisor may return cur == 0 and end == 0 if the block job has finished and was no-op. In this case libvirt reports cur = 1 and end = 1. Since 2.3.0.

`dom`: | pointer to domain object
`disk`: | path to the block device, or device shorthand
`info`: | pointer to a virDomainBlockJobInfo structure
`flags`: | bitwise-OR of virDomainBlockJobInfoFlags
`Returns`: | -1 in case of failure, 0 when nothing found, 1 when info was found.

### virDomainGetCPUStats ()

    int	virDomainGetCPUStats		(virDomainPtr domain,
    					 virTypedParameterPtr params,
    					 unsigned int nparams,
    					 int start_cpu,
    					 unsigned int ncpus,
    					 unsigned int flags)

Get statistics relating to CPU usage attributable to a single domain (in contrast to the statistics returned by virNodeGetCPUStats() for all processes on the host). @dom must be running (an inactive domain has no attributable cpu usage). On input, @params must contain at least @nparams * @ncpus entries, allocated by the caller. If @start_cpu is -1, then @ncpus must be 1, and the returned results reflect the statistics attributable to the entire domain (such as user and system time for the process as a whole). Otherwise, @start_cpu represents which cpu to start with, and @ncpus represents how many consecutive processors to query, with statistics attributable per processor (such as per-cpu usage). If @ncpus is larger than the number of cpus available to query, then the trailing part of the array will be unpopulated. The remote driver imposes a limit of 128 @ncpus and 16 @nparams; the number of parameters per cpu should not exceed 16, but if you have a host with more than 128 CPUs, your program should split the request into multiple calls. As special cases, if @params is NULL and @nparams is 0 and @ncpus is 1, and the return value will be how many statistics are available for the given @start_cpu. This number may be different for @start_cpu of -1 than for any non-negative value, but will be the same for all non-negative @start_cpu. Likewise, if @params is NULL and @nparams is 0 and @ncpus is 0, the number of cpus available to query is returned. From the host perspective, this would typically match the cpus member of virNodeGetInfo(), but might be less due to host cpu hotplug. For now, @flags is unused, and the statistics all relate to the usage from the host perspective. It is possible that a future version will support a flag that queries the cpu usage from the guest's perspective, where the maximum cpu to query would be related to virDomainGetVcpusFlags() rather than virNodeGetInfo(). An individual guest vcpu cannot be reliably mapped back to a specific host cpu unless a single-processor vcpu pinning was used, but when @start_cpu is -1, any difference in usage between a host and guest perspective would serve as a measure of hypervisor overhead. Typical use sequence is below. getting total stats: set start_cpu as -1, ncpus 1 virDomainGetCPUStats(dom, NULL, 0, -1, 1, 0); // nparams params = calloc(nparams, sizeof(virTypedParameter)) virDomainGetCPUStats(dom, params, nparams, -1, 1, 0); // total stats. getting per-cpu stats: virDomainGetCPUStats(dom, NULL, 0, 0, 0, 0); // ncpus virDomainGetCPUStats(dom, NULL, 0, 0, 1, 0); // nparams params = calloc(ncpus * nparams, sizeof(virTypedParameter)); virDomainGetCPUStats(dom, params, nparams, 0, ncpus, 0); // per-cpu stats

`domain`: | domain to query
`params`: | array to populate on output
`nparams`: | number of parameters per cpu
`start_cpu`: | which cpu to start with, or -1 for summary
`ncpus`: | how many cpus to query
`flags`: | bitwise-OR of virTypedParameterFlags
`Returns`: | -1 on failure, or the number of statistics that were populated per cpu on success (this will be less than the total number of populated @params, unless @ncpus was 1; and may be less than @nparams). The populated parameters start at each stride of @nparams, which means the results may be discontiguous; any unpopulated parameters will be zeroed on success (this includes skipped elements if @nparams is too large, and tail elements if @ncpus is too large). The caller is responsible for freeing any returned string parameters.

### virDomainGetConnect ()

    virConnectPtr	virDomainGetConnect	(virDomainPtr dom)

Provides the connection pointer associated with a domain. The reference counter on the connection is not increased by this call.

`dom`: | pointer to a domain
`Returns`: | the virConnectPtr or NULL in case of failure.

### virDomainGetControlInfo ()

    int	virDomainGetControlInfo		(virDomainPtr domain,
    					 virDomainControlInfoPtr info,
    					 unsigned int flags)

Extract details about current state of control interface to a domain.

`domain`: | a domain object
`info`: | pointer to a virDomainControlInfo structure allocated by the user
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainGetDiskErrors ()

    int	virDomainGetDiskErrors		(virDomainPtr dom,
    					 virDomainDiskErrorPtr errors,
    					 unsigned int maxerrors,
    					 unsigned int flags)

The function populates @errors array with all disks that encountered an I/O error. Disks with no error will not be returned in the @errors array. Each disk is identified by its target (the dev attribute of target subelement in domain XML), such as "vda", and accompanied with the error that was seen on it. The caller is also responsible for calling free() on each disk name returned. In a special case when @errors is NULL and @maxerrors is 0, the function returns preferred size of @errors that the caller should use to get all disk errors. Since calling virDomainGetDiskErrors(dom, NULL, 0, 0) to get preferred size of @errors array and getting the errors are two separate operations, new disks may be hotplugged to the domain and new errors may be encountered between the two calls. Thus, this function may not return all disk errors because the supplied array is not large enough. Such errors may, however, be detected by listening to domain events.

`dom`: | a domain object
`errors`: | array to populate on output
`maxerrors`: | size of @errors array
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | number of disks with errors filled in the @errors array or -1 on error.

### virDomainGetEmulatorPinInfo ()

    int	virDomainGetEmulatorPinInfo	(virDomainPtr domain,
    					 unsigned char * cpumap,
    					 int maplen,
    					 unsigned int flags)

Query the CPU affinity setting of all emulator threads of domain, store it in cpumap.

`domain`: | pointer to domain object, or NULL for Domain0
`cpumap`: | pointer to a bit map of real CPUs for all emulator threads of this domain (in 8-bit bytes) (OUT) There is only one cpumap for all emulator threads. Must not be NULL.
`maplen`: | the number of bytes in one cpumap, from 1 up to size of CPU map. Must be positive.
`flags`: | bitwise-OR of virDomainModificationImpact Must not be VIR_DOMAIN_AFFECT_LIVE and VIR_DOMAIN_AFFECT_CONFIG concurrently.
`Returns`: | 1 in case of success, 0 in case of no emulator threads are pined to pcpus, -1 in case of failure.

### virDomainGetFSInfo ()

    int	virDomainGetFSInfo		(virDomainPtr dom,
    					 virDomainFSInfoPtr ** info,
    					 unsigned int flags)

Get a list of mapping information for each mounted file systems within the specified guest and the disks.

`dom`: | a domain object
`info`: | a pointer to a variable to store an array of mount points information
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | the number of returned mount points, or -1 in case of error. On success, the array of the information is stored into @info. The caller is responsible for calling virDomainFSInfoFree() on each array element, then calling free() on @info. On error, @info is set to NULL.

### virDomainGetGuestVcpus ()

    int	virDomainGetGuestVcpus		(virDomainPtr domain,
    					 virTypedParameterPtr * params,
    					 unsigned int * nparams,
    					 unsigned int flags)

Queries the guest agent for state and information regarding vCPUs from guest's perspective. The reported data depends on the guest agent implementation. Reported fields stored in @params: 'vcpus': string containing bitmap representing vCPU ids as reported by the guest 'online': string containing bitmap representing online vCPUs as reported by the guest agent. 'offlinable': string containing bitmap representing ids of vCPUs that can be offlined This API requires the VM to run. The caller is responsible for calling virTypedParamsFree to free memory returned in @params.

`domain`: | pointer to domain object
`params`: | pointer that will be filled with an array of typed parameters
`nparams`: | pointer filled with number of elements in @params
`flags`: | currently unused, callers shall pass 0

Fetch IOThreads of an active domain including the cpumap information to determine on which CPU the IOThread has affinity to run.

`dom`: | a domain object
`info`: | pointer to an array of virDomainIOThreadInfo structures (OUT)
`flags`: | bitwise-OR of virDomainModificationImpact Must not be VIR_DOMAIN_AFFECT_LIVE and VIR_DOMAIN_AFFECT_CONFIG concurrently.
`Returns`: | the number of IOThreads or -1 in case of error. On success, the array of information is stored into @info. The caller is responsible for calling virDomainIOThreadInfoFree() on each array element, then calling free() on @info. On error, @info is set to NULL.

### virDomainGetInfo ()

    					 const char * device,
    					 virTypedParameterPtr params,
    					 int * nparams,
    					 unsigned int flags)

Get all interface parameters. On input, @nparams gives the size of the @params array; on output, @nparams gives how many slots were filled with parameter information, which might be less but will not exceed the input value. As a special case, calling with @params as NULL and @nparams as 0 on input will cause @nparams on output to contain the number of parameters supported by the hypervisor. The caller should then allocate @params array, i.e. (sizeof(@virTypedParameter) * @nparams) bytes and call the API again. See virDomainGetMemoryParameters() for an equivalent usage example. This function may require privileged access to the hypervisor. This function expects the caller to allocate the @params.

    					 int * type,
    					 virTypedParameterPtr * params,
    					 int * nparams,
    					 unsigned int flags)

Extract information about progress of a background job on a domain. Will return an error if the domain is not active. The function returns a superset of progress information provided by virDomainGetJobInfo. Possible fields returned in @params are defined by VIR_DOMAIN_JOB_* macros and new fields will likely be introduced in the future so callers may receive fields that they do not understand in case they talk to a newer server. When @flags contains VIR_DOMAIN_JOB_STATS_COMPLETED, the function will return statistics about a recently completed job. Specifically, this flag may be used to query statistics of a completed incoming pre-copy migration (statistics for post-copy migration are only available on the source host). Statistics of a completed job are automatically destroyed once read or when libvirtd is restarted. Note that time information returned for completed migrations may be completely irrelevant unless both source and destination hosts have synchronized time (i.e., NTP daemon is running on both of them). The statistics of a completed job can also be obtained by listening to a VIR_DOMAIN_EVENT_ID_JOB_COMPLETED event (on the source host in case of a migration job).

As a special case, calling with @params as NULL and @nparams as 0 on input will cause @nparams on output to contain the number of parameters supported by the hypervisor. The caller should then allocate @params array, i.e. (sizeof(@virTypedParameter) * @nparams) bytes and call the API again. Here is a sample code snippet: if (virDomainGetMemoryParameters(dom, NULL, &nparams, 0) == 0 && nparams != 0) { if ((params = malloc(sizeof(*params) * nparams)) == NULL) goto error; memset(params, 0, sizeof(*params) * nparams); if (virDomainGetMemoryParameters(dom, params, &nparams, 0)) goto error; } This function may require privileged access to the hypervisor.

Retrieves the appropriate domain element given by @type. If VIR_DOMAIN_METADATA_ELEMENT is requested parameter @uri must be set to the name of the namespace the requested elements belong to, otherwise must be NULL. If an element of the domain XML is not present, the resulting error will be VIR_ERR_NO_DOMAIN_METADATA. This method forms a shortcut for seeing information from virDomainSetMetadata() without having to go through virDomainGetXMLDesc(). @flags controls whether the live domain or persistent configuration will be queried.

`domain`: | a domain object
`type`: | type of metadata, from virDomainMetadataType

    					 unsigned int flags)

Get all numa parameters. On input, @nparams gives the size of the @params array; on output, @nparams gives how many slots were filled with parameter information, which might be less but will not exceed the input value. As a special case, calling with @params as NULL and @nparams as 0 on input will cause @nparams on output to contain the number of parameters supported by the hypervisor. The caller should then allocate @params array, i.e. (sizeof(@virTypedParameter) * @nparams) bytes and call the API again. See virDomainGetMemoryParameters() for an equivalent usage example. This function may require privileged access to the hypervisor. This function expects the caller to allocate the @params.

`domain`: | pointer to domain object
`params`: | pointer to scheduler parameter objects (return value)
`nparams`: | pointer to number of scheduler parameter objects (this value should generally be as large as the returned value nparams of virDomainGetSchedulerType()); input and output

    					 unsigned char * cpumaps,
    					 int maplen)

Extract information about virtual CPUs of domain, store it in info array and also in cpumaps if this pointer isn't NULL. This call may fail on an inactive domain. See also virDomainGetVcpuPinInfo for querying just cpumaps, including on an inactive domain.

`domain`: | pointer to domain object, or NULL for Domain0
`info`: | pointer to an array of virVcpuInfo structures (OUT)
`maxinfo`: | number of structures in info array
`cpumaps`: | pointer to a bit map of real CPUs for all vcpus of this domain (in 8-bit bytes) (OUT) If cpumaps is NULL, then no cpumap information is returned by the API. It's assumed there is <maxinfo> cpumap in cpumaps array. The memory allocated to cpumaps must be (maxinfo * maplen) bytes (ie: calloc(maxinfo, maplen)). One cpumap inside cpumaps has the format described in virDomainPinVcpu() API.

`Returns`: | the number of info filled in case of success, -1 in case of failure.

### virDomainGetVcpusFlags ()

    int	virDomainGetVcpusFlags		(virDomainPtr domain,
    					 unsigned int flags)

Query the number of virtual CPUs used by the domain. Note that this call may fail if the underlying virtualization hypervisor does not support it. This function may require privileged access to the hypervisor. If @flags includes VIR_DOMAIN_AFFECT_LIVE, this will query a running domain (which will fail if domain is not active); if it includes VIR_DOMAIN_AFFECT_CONFIG, this will query the XML description of the domain. It is an error to set both flags. If neither flag is set (that is, VIR_DOMAIN_AFFECT_CURRENT), then the configuration queried depends on whether the domain is currently running. If @flags includes VIR_DOMAIN_VCPU_MAXIMUM, then the maximum virtual CPU limit is queried. Otherwise, this call queries the current virtual CPU count. If @flags includes VIR_DOMAIN_VCPU_GUEST, then the state of the processors is queried in the guest instead of the hypervisor. This flag is only usable on live domains. Guest agent may be needed for this flag to be available.

`domain`: | pointer to domain object, or NULL for Domain0
`flags`: | bitwise-OR of virDomainVcpuFlags
`Returns`: | the number of vCPUs in case of success, -1 in case of failure.

### virDomainGetXMLDesc ()

    char *	virDomainGetXMLDesc		(virDomainPtr domain,
    					 unsigned int flags)

Provide an XML description of the domain. The description may be reused later to relaunch the domain with virDomainCreateXML(). No security-sensitive data will be included unless @flags contains VIR_DOMAIN_XML_SECURE; this flag is rejected on read-only connections. If @flags includes VIR_DOMAIN_XML_INACTIVE, then the XML represents the configuration that will be used on the next boot of a persistent domain; otherwise, the configuration represents the currently running domain. If @flags contains VIR_DOMAIN_XML_UPDATE_CPU, then the portion of the domain XML describing CPU capabilities is modified to match actual capabilities of the host. If @flags contains VIR_DOMAIN_XML_MIGRATABLE, the XML is altered to assist in migrations, since the source and destination may be running different libvirt versions. This may include trimming redundant or default information that might confuse an older recipient, or exposing internal details that aid a newer recipient; this flag is rejected on read-only connections, and the resulting XML might not validate against the schema, so it is mainly for internal use.

`domain`: | a domain object
`flags`: | bitwise-OR of virDomainXMLFlags
`Returns`: | a 0 terminated UTF-8 encoded XML instance, or NULL in case of error. The caller must free() the returned value.

### virDomainHasManagedSaveImage ()

### virDomainInterfaceAddresses ()

    int	virDomainInterfaceAddresses	(virDomainPtr dom,
    					 virDomainInterfacePtr ** ifaces,
    					 unsigned int source,
    					 unsigned int flags)

Return a pointer to the allocated array of pointers to interfaces present in given domain along with their IP and MAC addresses. Note that single interface can have multiple or even 0 IP addresses. This API dynamically allocates the virDomainInterfacePtr struct based on how many interfaces domain @dom has, usually there's 1:1 correlation. The count of the interfaces is returned as the return value. If @source is VIR_DOMAIN_INTERFACE_ADDRESSES_SRC_LEASE, the DHCP lease file associated with any virtual networks will be examined to obtain the interface addresses. This only returns data for interfaces which are connected to virtual networks managed by libvirt. If @source is VIR_DOMAIN_INTERFACE_ADDRESSES_SRC_AGENT, a configured guest agent is needed for successful return from this API. Moreover, if guest agent is used then the interface name is the one seen by guest OS. To match such interface with the one from @dom XML use MAC address or IP range. If @source is VIR_DOMAIN_INTERFACE_ADDRESSES_SRC_ARP, the host ARP table will be check to obtain the interface addresses. As the arp cache refreshes in time, the returned ip address may be unreachable. Depending on the route table config of the guest, the returned mac address may be duplicated. Note that for some @source values some pieces of returned @ifaces might be unset (e.g. VIR_DOMAIN_INTERFACE_ADDRESSES_SRC_ARP does not set IP address prefix as ARP table does not have any notion of that). @ifaces->name and @ifaces->hwaddr are never NULL. The caller *must* free @ifaces when no longer needed. Usual use case looks like this: virDomainInterfacePtr *ifaces = NULL; int ifaces_count = 0; size_t i, j; virDomainPtr dom = ... obtain a domain here ...; if ((ifaces_count = virDomainInterfaceAddresses(dom, &ifaces, VIR_DOMAIN_INTERFACE_ADDRESSES_SRC_LEASE)) < 0) goto cleanup; ... do something with returned values, for example: for (i = 0; i < ifaces_count; i++) { printf("name: %s", ifaces[i]->name); if (ifaces[i]->hwaddr) printf(" hwaddr: %s", ifaces[i]->hwaddr); for (j = 0; j < ifaces[i]->naddrs; j++) { virDomainIPAddressPtr ip_addr = ifaces[i]->addrs + j; printf("[addr: %s prefix: %d type: %d]", ip_addr->addr, ip_addr->prefix, ip_addr->type); } printf("\n"); } cleanup: if (ifaces && ifaces_count > 0) for (i = 0; i < ifaces_count; i++) virDomainInterfaceFree(ifaces[i]); free(ifaces);

`dom`: | domain object
`ifaces`: | pointer to an array of pointers pointing to interface objects
`source`: | one of the virDomainInterfaceAddressesSource constants

### virDomainInterfaceStats ()

    int	virDomainInterfaceStats		(virDomainPtr dom,
    					 const char * device,
    					 virDomainInterfaceStatsPtr stats,
    					 size_t size)

This function returns network interface stats for interfaces attached to the domain. The @device parameter is the network interface either by name or MAC address. Domains may have more than one network interface. To get stats for each you should make multiple calls to this function. Individual fields within the stats structure may be returned as -1, which indicates that the hypervisor does not support that particular statistic. The returned stats are from domain's point of view.

`dom`: | pointer to the domain object
`device`: | the interface name or MAC address
`stats`: | network interface stats (returned)
`size`: | size of stats structure
`Returns`: | 0 in case of success or -1 in case of failure.

### virDomainListGetStats ()

    int	virDomainListGetStats		(virDomainPtr * doms,
    					 unsigned int stats,
    					 virDomainStatsRecordPtr ** retStats,
    					 unsigned int flags)

Query statistics for domains provided by @doms. Note that all domains in @doms must share the same connection. Report statistics of various parameters for a running VM according to @stats field. The statistics are returned as an array of structures for each queried domain. The structure contains an array of typed parameters containing the individual statistics. The typed parameter name for each statistic field consists of a dot-separated string containing name of the requested group followed by a group specific description of the statistic value. The statistic groups are enabled using the @stats parameter which is a binary-OR of enum virDomainStatsTypes. The stats groups are documented in virConnectGetAllDomainStats. Using 0 for @stats returns all stats groups supported by the given hypervisor. Specifying VIR_CONNECT_GET_ALL_DOMAINS_STATS_ENFORCE_STATS as @flags makes the function return error in case some of the stat types in @stats were not recognized by the daemon. However, even with this flag, a hypervisor may omit individual fields within a known group if the information is not available; as an extreme example, a supported group may produce zero fields for offline domains if the statistics are meaningful only for a running domain. Passing VIR_CONNECT_GET_ALL_DOMAINS_STATS_NOWAIT in @flags means when libvirt is unable to fetch stats for any of the domains (for whatever reason) only a subset of statistics is returned for the domain. That subset being statistics that don't involve querying the underlying hypervisor. Note that any of the domain list filtering flags in @flags may be rejected by this function.

`doms`: | NULL terminated array of domains
`stats`: | stats to return, binary-OR of virDomainStatsTypes
`retStats`: | Pointer that will be filled with the array of returned stats
`flags`: | extra flags; binary-OR of virConnectGetAllDomainStatsFlags
`Returns`: | the count of returned statistics structures on success, -1 on error. The requested data are returned in the @retStats parameter. The returned array should be freed by the caller. See virDomainStatsRecordListFree. Note that the count of returned stats may be less than the domain count provided via @doms.

    					 int id)

Try to find a domain based on the hypervisor ID number Note that this won't work for inactive domains which have an ID of -1, in that case a lookup based on the Name or UUId need to be done instead. virDomainFree should be used to free the resources after the domain object is no longer needed.

`conn`: | pointer to the hypervisor connection
`id`: | the domain ID number
`Returns`: | a new domain object or NULL in case of failure. If the domain cannot be found, then VIR_ERR_NO_DOMAIN error is raised.

### virDomainLookupByName ()

    virDomainPtr	virDomainLookupByName	(virConnectPtr conn,
    					 const char * name)

Try to lookup a domain on the given hypervisor based on its name. virDomainFree should be used to free the resources after the domain object is no longer needed.

`conn`: | pointer to the hypervisor connection
`name`: | name for the domain
`Returns`: | a new domain object or NULL in case of failure. If the domain cannot be found, then VIR_ERR_NO_DOMAIN error is raised.

### virDomainLookupByUUID ()

    virDomainPtr	virDomainLookupByUUID	(virConnectPtr conn,
    					 const unsigned char * uuid)

Try to lookup a domain on the given hypervisor based on its UUID. virDomainFree should be used to free the resources after the domain object is no longer needed.

`conn`: | pointer to the hypervisor connection
`uuid`: | the raw UUID for the domain
`Returns`: | a new domain object or NULL in case of failure. If the domain cannot be found, then VIR_ERR_NO_DOMAIN error is raised.

### virDomainLookupByUUIDString ()

    virDomainPtr	virDomainLookupByUUIDString	(virConnectPtr conn,
    						 const char * uuidstr)

Try to lookup a domain on the given hypervisor based on its UUID. virDomainFree should be used to free the resources after the domain object is no longer needed.

`conn`: | pointer to the hypervisor connection
`uuidstr`: | the string UUID for the domain
`Returns`: | a new domain object or NULL in case of failure. If the domain cannot be found, then VIR_ERR_NO_DOMAIN error is raised.

### virDomainManagedSave ()

    int	virDomainManagedSave		(virDomainPtr dom,
    					 unsigned int flags)

This method will suspend a domain and save its memory contents to a file on disk. After the call, if successful, the domain is not listed as running anymore. The difference from virDomainSave() is that libvirt is keeping track of the saved state itself, and will reuse it once the domain is being restarted (automatically or via an explicit libvirt call). As a result any running domain is sure to not have a managed saved image. This also implies that managed save only works on persistent domains, since the domain must still exist in order to use virDomainCreate() to restart it. If @flags includes VIR_DOMAIN_SAVE_BYPASS_CACHE, then libvirt will attempt to bypass the file system cache while creating the file, or fail if it cannot do so for the given system; this can allow less pressure on file system cache, but also risks slowing saves to NFS. Normally, the managed saved state will remember whether the domain was running or paused, and start will resume to the same state. Specifying VIR_DOMAIN_SAVE_RUNNING or VIR_DOMAIN_SAVE_PAUSED in @flags will override the default saved into the file. These two flags are mutually exclusive.

`dom`: | pointer to the domain
`flags`: | bitwise-OR of virDomainSaveRestoreFlags
`Returns`: | 0 in case of success or -1 in case of failure

### virDomainManagedSaveDefineXML ()

    int	virDomainManagedSaveDefineXML	(virDomainPtr domain,
    					 const char * dxml,
    					 unsigned int flags)

This updates the definition of a domain stored in a saved state file. @dxml can be used to alter host-specific portions of the domain XML that will be used on the next start of the domain. For example, it is possible to alter the backing filename that is associated with a disk device. Normally, the saved state file will remember whether the domain was running or paused, and restore defaults to the same state. Specifying VIR_DOMAIN_SAVE_RUNNING or VIR_DOMAIN_SAVE_PAUSED in @flags will override the default saved into the file; omitting both leaves the file's default unchanged. These two flags are mutually exclusive.

`domain`: | a domain object
`dxml`: | XML config for adjusting guest xml used on restore
`flags`: | bitwise-OR of virDomainSaveRestoreFlags
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainManagedSaveGetXMLDesc ()

    char *	virDomainManagedSaveGetXMLDesc	(virDomainPtr domain,
    					 unsigned int flags)

This method will extract the XML description of the managed save state file of a domain. No security-sensitive data will be included unless @flags contains VIR_DOMAIN_SAVE_IMAGE_XML_SECURE; this flag is rejected on read-only connections.

`domain`: | a domain object
`flags`: | bitwise-OR of supported virDomainSaveImageXMLFlags
`Returns`: | a 0 terminated UTF-8 encoded XML instance, or NULL in case of error. The caller must free() the returned value.

### virDomainManagedSaveRemove ()

    int	virDomainManagedSaveRemove	(virDomainPtr dom,
    					 unsigned int flags)

Remove any managed save image for this domain.

`dom`: | pointer to the domain
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | 0 in case of success, and -1 in case of error

### virDomainMemoryPeek ()

    int	virDomainMemoryPeek		(virDomainPtr dom,
    					 unsigned long long start,
    					 size_t size,
    					 void * buffer,
    					 unsigned int flags)

This function allows you to read the contents of a domain's memory. The memory which is read is controlled by the 'start', 'size' and 'flags' parameters. If 'flags' is VIR_MEMORY_VIRTUAL then the 'start' and 'size' parameters are interpreted as virtual memory addresses for whichever task happens to be running on the domain at the moment. Although this sounds haphazard it is in fact what you want in order to read Linux kernel state, because it ensures that pointers in the kernel image can be interpreted coherently. 'buffer' is the return buffer and must be at least 'size' bytes. 'size' may be 0 to test if the call would succeed. NB. The remote driver imposes a 64K byte limit on 'size'. For your program to be able to work reliably over a remote connection you should split large requests to <= 65536 bytes. However, with 0.9.13 this RPC limit has been raised to 1M byte. Starting with version 1.0.6 the RPC limit has been raised again. Now large requests up to 16M byte are supported.

`dom`: | pointer to the domain object
`start`: | start of memory to peek
`size`: | size of memory to peek
`buffer`: | return buffer (must be at least size bytes)
`flags`: | bitwise-OR of virDomainMemoryFlags
`Returns`: | 0 in case of success or -1 in case of failure.

### virDomainMemoryStats ()

    int	virDomainMemoryStats		(virDomainPtr dom,
    					 virDomainMemoryStatPtr stats,
    					 unsigned int nr_stats,
    					 unsigned int flags)

This function provides memory statistics for the domain. Up to 'nr_stats' elements of 'stats' will be populated with memory statistics from the domain. Only statistics supported by the domain, the driver, and this version of libvirt will be returned. Memory Statistics: VIR_DOMAIN_MEMORY_STAT_SWAP_IN: The total amount of data read from swap space (in kb). VIR_DOMAIN_MEMORY_STAT_SWAP_OUT: The total amount of memory written out to swap space (in kb). VIR_DOMAIN_MEMORY_STAT_MAJOR_FAULT: The number of page faults that required disk IO to service. VIR_DOMAIN_MEMORY_STAT_MINOR_FAULT: The number of page faults serviced without disk IO. VIR_DOMAIN_MEMORY_STAT_UNUSED: The amount of memory which is not being used for any purpose (in kb). VIR_DOMAIN_MEMORY_STAT_AVAILABLE: The total amount of memory available to the domain's OS (in kb). VIR_DOMAIN_MEMORY_STAT_USABLE: How much the balloon can be inflated without pushing the guest system to swap, corresponds to 'Available' in /proc/meminfo VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON: Current balloon value (in kb). VIR_DOMAIN_MEMORY_STAT_LAST_UPDATE Timestamp of the last statistic VIR_DOMAIN_MEMORY_STAT_DISK_CACHES Memory that can be reclaimed without additional I/O, typically disk caches (in kb). VIR_DOMAIN_MEMORY_STAT_HUGETLB_PGALLOC The amount of successful huge page allocations from inside the domain VIR_DOMAIN_MEMORY_STAT_HUGETLB_PGFAIL The amount of failed huge page allocations from inside the domain

`dom`: | pointer to the domain object
`stats`: | nr_stats-sized array of stat structures (returned)
`nr_stats`: | number of memory statistics requested
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | The number of stats provided or -1 in case of failure.

    					 virConnectPtr dconn,
    					 unsigned long flags,
    					 const char * dname,
    					 const char * uri,
    					 unsigned long bandwidth)

Migrate the domain object from its current host to the destination host given by dconn (a connection to the destination host). This function is similar to virDomainMigrate3, but it only supports a fixed set of parameters: @dname corresponds to VIR_MIGRATE_PARAM_DEST_NAME, @uri is VIR_MIGRATE_PARAM_URI, and @bandwidth is VIR_MIGRATE_PARAM_BANDWIDTH. virDomainFree should be used to free the resources after the returned domain object is no longer needed.

    					 virConnectPtr dconn,
    					 const char * dxml,
    					 unsigned long flags,
    					 const char * dname,
    					 const char * uri,
    					 unsigned long bandwidth)

Migrate the domain object from its current host to the destination host given by dconn (a connection to the destination host). This function is similar to virDomainMigrate3, but it only supports a fixed set of parameters: @dxml corresponds to VIR_MIGRATE_PARAM_DEST_XML, @dname is VIR_MIGRATE_PARAM_DEST_NAME, @uri is VIR_MIGRATE_PARAM_URI, and @bandwidth is VIR_MIGRATE_PARAM_BANDWIDTH. virDomainFree should be used to free the resources after the returned domain object is no longer needed.

`bandwidth`: | (optional) specify migration bandwidth limit in MiB/s
`Returns`: | the new domain object if the migration was successful, or NULL in case of error. Note that the new domain object exists in the scope of the destination connection (dconn).

### virDomainMigrate3 ()

    virDomainPtr	virDomainMigrate3	(virDomainPtr domain,
    					 virConnectPtr dconn,
    					 virTypedParameterPtr params,
    					 unsigned int nparams,
    					 unsigned int flags)

Migrate the domain object from its current host to the destination host given by dconn (a connection to the destination host). See VIR_MIGRATE_PARAM_* and virDomainMigrateFlags for detailed description of accepted migration parameters and flags. See virDomainMigrateFlags documentation for description of individual flags. VIR_MIGRATE_TUNNELLED and VIR_MIGRATE_PEER2PEER are not supported by this API, use virDomainMigrateToURI3 instead. There are many limitations on migration imposed by the underlying technology - for example it may not be possible to migrate between different processors even with the same architecture, or between different types of hypervisor. virDomainFree should be used to free the resources after the returned domain object is no longer needed.

`domain`: | a domain object
`dconn`: | destination host (a connection object)
`params`: | (optional) migration parameters
`nparams`: | (optional) number of migration parameters in @params
`flags`: | bitwise-OR of virDomainMigrateFlags
`Returns`: | the new domain object if the migration was successful, or NULL in case of error. Note that the new domain object exists in the scope of the destination connection (dconn).

### virDomainMigrateGetCompressionCache ()

    int	virDomainMigrateGetCompressionCache	(virDomainPtr domain,
    						 unsigned long long * cacheSize,
    						 unsigned int flags)

Gets current size of the cache (in bytes) used for compressing repeatedly transferred memory pages during live migration.

`domain`: | a domain object
`cacheSize`: | return value of current size of the cache (in bytes)
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | 0 in case of success, -1 otherwise.

### virDomainMigrateGetMaxDowntime ()

    int	virDomainMigrateGetMaxDowntime	(virDomainPtr domain,
    					 unsigned long long * downtime,
    					 unsigned int flags)

Gets current maximum tolerable time for which the domain may be paused at the end of live migration.

`domain`: | a domain object
`downtime`: | return value of the maximum tolerable downtime for live migration, in milliseconds

    int	virDomainMigrateGetMaxSpeed	(virDomainPtr domain,
    					 unsigned long * bandwidth,
    					 unsigned int flags)

Get the current maximum bandwidth (in MiB/s) that will be used if the domain is migrated. Not all hypervisors will support a bandwidth limit. When VIR_DOMAIN_MIGRATE_MAX_SPEED_POSTCOPY is set in @flags, this API gets the current maximum bandwidth for the post-copy phase of the migration.

`domain`: | a domain object
`bandwidth`: | return value of current migration bandwidth limit in MiB/s
`flags`: | bitwise-OR of virDomainMigrateMaxSpeedFlags
`Returns`: | 0 in case of success, -1 otherwise.

### virDomainMigrateSetCompressionCache ()

    int	virDomainMigrateSetCompressionCache	(virDomainPtr domain,
    						 unsigned long long cacheSize,
    						 unsigned int flags)

Sets size of the cache (in bytes) used for compressing repeatedly transferred memory pages during live migration. It's supposed to be called while the domain is being live-migrated as a reaction to migration progress and increasing number of compression cache misses obtained from virDomainGetJobStats.

`domain`: | a domain object
`cacheSize`: | size of the cache (in bytes) used for compression
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | 0 in case of success, -1 otherwise.

### virDomainMigrateSetMaxDowntime ()

    int	virDomainMigrateSetMaxDowntime	(virDomainPtr domain,
    					 unsigned long long downtime,
    					 unsigned int flags)

Sets maximum tolerable time for which the domain is allowed to be paused at the end of live migration. It's supposed to be called while the domain is being live-migrated as a reaction to migration progress.

`domain`: | a domain object
`downtime`: | maximum tolerable downtime for live migration, in milliseconds
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | 0 in case of success, -1 otherwise.

### virDomainMigrateSetMaxSpeed ()

    int	virDomainMigrateSetMaxSpeed	(virDomainPtr domain,
    					 unsigned long bandwidth,
    					 unsigned int flags)

The maximum bandwidth (in MiB/s) that will be used to do migration can be specified with the bandwidth parameter. Not all hypervisors will support a bandwidth cap. When VIR_DOMAIN_MIGRATE_MAX_SPEED_POSTCOPY is set in @flags, this API sets the maximum bandwidth for the post-copy phase of the migration.

`domain`: | a domain object
`bandwidth`: | migration bandwidth limit in MiB/s
`flags`: | bitwise-OR of virDomainMigrateMaxSpeedFlags
`Returns`: | 0 in case of success, -1 otherwise.

### virDomainMigrateStartPostCopy ()

    int	virDomainMigrateStartPostCopy	(virDomainPtr domain,
    					 unsigned int flags)

Starts post-copy migration. This function has to be called while migration (initiated with VIR_MIGRATE_POSTCOPY flag) is in progress. Traditional pre-copy migration iteratively walks through guest memory pages and migrates those that changed since the previous iteration. The iterative phase stops when the number of dirty pages is low enough so that the virtual CPUs can be paused, all dirty pages transferred to the destination, where the virtual CPUs are unpaused, and all this can happen within a predefined downtime period. It's clear that this process may never converge if downtime is too short and/or the guest keeps changing a lot of memory pages. When migration is switched to post-copy mode, the virtual CPUs are paused immediately, only a minimum set of pages is transferred, and the CPUs are unpaused on destination. The source keeps sending all remaining memory pages to the destination while the guest is already running there. Whenever the guest tries to read a memory page which has not been migrated yet, the hypervisor has to tell the source to transfer that page in a priority channel. To minimize such page faults, it is a good idea to run at least one iteration of pre-copy migration before switching to post-copy. Post-copy migration is guaranteed to converge since each page is transferred at most once no matter how fast it changes. On the other hand once the guest is running on the destination host, the migration can no longer be rolled back because none of the hosts has complete state. If this happens, libvirt will leave the domain paused on both hosts with VIR_DOMAIN_PAUSED_POSTCOPY_FAILED reason. It's up to the upper layer to decide what to do in such case. Because of this, libvirt will refuse to cancel post-copy migration via virDomainAbortJob. The following domain life cycle events are emitted during post-copy migration: VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY (on the source) -- migration entered post-copy mode. VIR_DOMAIN_EVENT_RESUMED_POSTCOPY (on the destination) -- the guest is running on the destination host while some of its memory pages still remain on the source host; neither the source nor the destination host contain a complete guest state from this point until migration finishes. VIR_DOMAIN_EVENT_RESUMED_MIGRATED (on the destination), VIR_DOMAIN_EVENT_STOPPED_MIGRATED (on the source) -- migration finished successfully and the destination host holds a complete guest state. VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY_FAILED (on the destination) -- emitted when migration fails in post-copy mode and it's unclear whether any of the hosts has a complete guest state. The progress of a post-copy migration can be monitored normally using virDomainGetJobStats on the source host. Fetching statistics of a completed post-copy migration can also be done on the source host (by calling virDomainGetJobStats or listening to VIR_DOMAIN_EVENT_ID_JOB_COMPLETED event, but (in contrast to pre-copy migration) the statistics are not available on the destination host. Thus, VIR_DOMAIN_EVENT_ID_JOB_COMPLETED event is the only way of getting statistics of a completed post-copy migration of a transient domain (because the domain is removed after migration and there's no domain to run virDomainGetJobStats on).

`domain`: | a domain object
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | 0 in case of success, -1 otherwise.

### virDomainMigrateToURI ()

    int	virDomainMigrateToURI		(virDomainPtr domain,
    					 const char * duri,
    					 unsigned long flags,
    					 const char * dname,
    					 unsigned long bandwidth)

Migrate the domain object from its current host to the destination host given by duri. This function is similar to virDomainMigrateToURI3, but it only supports a fixed set of parameters: @dname corresponds to VIR_MIGRATE_PARAM_DEST_NAME, and @bandwidth corresponds to VIR_MIGRATE_PARAM_BANDWIDTH. The operation of this API hinges on the VIR_MIGRATE_PEER2PEER flag. If the VIR_MIGRATE_PEER2PEER flag IS set, the @duri parameter must be a valid libvirt connection URI, by which the source libvirt driver can connect to the destination libvirt. In other words, @duri corresponds to @dconnuri of virDomainMigrateToURI3. If the VIR_MIGRATE_PEER2PEER flag is NOT set, the @duri parameter takes a hypervisor specific URI used to initiate the migration. In this case @duri corresponds to VIR_MIGRATE_PARAM_URI of virDomainMigrateToURI3.

`domain`: | a domain object
`duri`: | mandatory URI for the destination host
`flags`: | bitwise-OR of virDomainMigrateFlags
`dname`: | (optional) rename domain to this at destination
`bandwidth`: | (optional) specify migration bandwidth limit in MiB/s
`Returns`: | 0 if the migration succeeded, -1 upon error.

### virDomainMigrateToURI2 ()

    int	virDomainMigrateToURI2		(virDomainPtr domain,
    					 const char * dconnuri,
    					 const char * miguri,
    					 const char * dxml,
    					 unsigned long flags,
    					 const char * dname,
    					 unsigned long bandwidth)

Migrate the domain object from its current host to the destination host given by @dconnuri. This function is similar to virDomainMigrateToURI3, but it only supports a fixed set of parameters: @miguri corresponds to VIR_MIGRATE_PARAM_URI, @dxml is VIR_MIGRATE_PARAM_DEST_XML, @dname is VIR_MIGRATE_PARAM_DEST_NAME, and @bandwidth corresponds to VIR_MIGRATE_PARAM_BANDWIDTH. The operation of this API hinges on the VIR_MIGRATE_PEER2PEER flag. If the VIR_MIGRATE_PEER2PEER flag IS set, the @dconnuri parameter must be a valid libvirt connection URI, by which the source libvirt driver can connect to the destination libvirt. In other words, @dconnuri has the same semantics as in virDomainMigrateToURI3. If the VIR_MIGRATE_PEER2PEER flag is NOT set, the @dconnuri must be NULL and the @miguri parameter takes a hypervisor specific URI used to initiate the migration. In this case @miguri corresponds to VIR_MIGRATE_PARAM_URI of virDomainMigrateToURI3.

`domain`: | a domain object
`dconnuri`: | (optional) URI for target libvirtd if @flags includes VIR_MIGRATE_PEER2PEER
`miguri`: | (optional) URI for invoking the migration, not if @flags includs VIR_MIGRATE_TUNNELLED
`dxml`: | (optional) XML config for launching guest on target
`flags`: | bitwise-OR of virDomainMigrateFlags
`dname`: | (optional) rename domain to this at destination
`bandwidth`: | (optional) specify migration bandwidth limit in MiB/s
`Returns`: | 0 if the migration succeeded, -1 upon error.

### virDomainMigrateToURI3 ()

    int	virDomainMigrateToURI3		(virDomainPtr domain,
    					 const char * dconnuri,
    					 virTypedParameterPtr params,
    					 unsigned int nparams,
    					 unsigned int flags)

Migrate the domain object from its current host to the destination host given by URI. See VIR_MIGRATE_PARAM_* and virDomainMigrateFlags for detailed description of accepted migration parameters and flags. The operation of this API hinges on the VIR_MIGRATE_PEER2PEER flag. If the VIR_MIGRATE_PEER2PEER flag is set, the @dconnuri parameter must be a valid libvirt connection URI, by which the source libvirt daemon can connect to the destination libvirt. If the VIR_MIGRATE_PEER2PEER flag is NOT set, then @dconnuri must be NULL and VIR_MIGRATE_PARAM_URI migration parameter must be filled in with hypervisor specific URI used to initiate the migration. The uri_transports element of the hypervisor capabilities XML includes supported URI schemes. This is called "direct" migration. Not all hypervisors support this mode of migration, so if the VIR_MIGRATE_PEER2PEER flag is not set, then it may be necessary to use the alternative virDomainMigrate3 API providing an explicit virConnectPtr for the destination host. There are many limitations on migration imposed by the underlying technology - for example it may not be possible to migrate between different processors even with the same architecture, or between different types of hypervisor.

`domain`: | a domain object
`dconnuri`: | (optional) URI for target libvirtd if @flags includes VIR_MIGRATE_PEER2PEER
`params`: | (optional) migration parameters
`nparams`: | (optional) number of migration parameters in @params
`flags`: | bitwise-OR of virDomainMigrateFlags
`Returns`: | 0 if the migration succeeded, -1 upon error.

### virDomainOpenChannel ()

    int	virDomainOpenChannel		(virDomainPtr dom,
    					 const char * name,
    					 virStreamPtr st,
    					 unsigned int flags)

This opens the host interface associated with a channel device on a guest, if the host interface is supported. If @name is given, it can match either the device alias (e.g. "channel0"), or the virtio target name (e.g. "org.qemu.guest_agent.0"). If @name is omitted, then the first channel is opened. The channel is associated with the passed in @st stream, which should have been opened in non-blocking mode for bi-directional I/O. By default, when @flags is 0, the open will fail if libvirt detects that the channel is already in use by another client; passing VIR_DOMAIN_CHANNEL_FORCE will cause libvirt to forcefully remove the other client prior to opening this channel.

`dom`: | a domain object
`name`: | the channel name, or NULL
`st`: | a stream to associate with the channel
`flags`: | bitwise-OR of virDomainChannelFlags
`Returns`: | 0 if the channel was opened, -1 on error

### virDomainOpenConsole ()

    int	virDomainOpenConsole		(virDomainPtr dom,
    					 const char * dev_name,
    					 virStreamPtr st,
    					 unsigned int flags)

This opens the backend associated with a console, serial or parallel port device on a guest, if the backend is supported. If the @dev_name is omitted, then the first console or serial device is opened. The console is associated with the passed in @st stream, which should have been opened in non-blocking mode for bi-directional I/O. By default, when @flags is 0, the open will fail if libvirt detects that the console is already in use by another client; passing VIR_DOMAIN_CONSOLE_FORCE will cause libvirt to forcefully remove the other client prior to opening this console. If flag VIR_DOMAIN_CONSOLE_SAFE the console is opened only in the case where the hypervisor driver supports safe (mutually exclusive) console handling. Older servers did not support either flag, and also did not forbid simultaneous clients on a console, with potentially confusing results. When passing @flags of 0 in order to support a wider range of server versions, it is up to the client to ensure mutual exclusion.

`dom`: | a domain object
`dev_name`: | the console, serial or parallel port device alias, or NULL
`st`: | a stream to associate with the console
`flags`: | bitwise-OR of virDomainConsoleFlags
`Returns`: | 0 if the console was opened, -1 on error

### virDomainOpenGraphics ()

    int	virDomainOpenGraphics		(virDomainPtr dom,
    					 unsigned int idx,
    					 int fd,
    					 unsigned int flags)

This will attempt to connect the file descriptor @fd, to the graphics backend of @dom. If @dom has multiple graphics backends configured, then @idx will determine which one is opened, starting from @idx 0. To disable any authentication, pass the VIR_DOMAIN_OPEN_GRAPHICS_SKIPAUTH constant for @flags. The caller should use an anonymous socketpair to open @fd before invocation. This method can only be used when connected to a local libvirt hypervisor, over a UNIX domain socket. Attempts to use this method over a TCP connection will always fail

`dom`: | pointer to domain object
`idx`: | index of graphics config to open
`fd`: | file descriptor to attach graphics to
`flags`: | bitwise-OR of virDomainOpenGraphicsFlags
`Returns`: | 0 on success, -1 on failure

### virDomainOpenGraphicsFD ()

    int	virDomainOpenGraphicsFD		(virDomainPtr dom,
    					 unsigned int idx,
    					 unsigned int flags)

This will create a socket pair connected to the graphics backend of @dom. One end of the socket will be returned on success, and the other end is handed to the hypervisor. If @dom has multiple graphics backends configured, then @idx will determine which one is opened, starting from @idx 0. To disable any authentication, pass the VIR_DOMAIN_OPEN_GRAPHICS_SKIPAUTH constant for @flags. This method can only be used when connected to a local libvirt hypervisor, over a UNIX domain socket. Attempts to use this method over a TCP connection will always fail.

`dom`: | pointer to domain object
`idx`: | index of graphics config to open
`flags`: | bitwise-OR of virDomainOpenGraphicsFlags
`Returns`: | an fd on success, -1 on failure

### virDomainPMSuspendForDuration ()

    int	virDomainPMSuspendForDuration	(virDomainPtr dom,
    					 unsigned int target,
    					 unsigned long long duration,
    					 unsigned int flags)

Attempt to have the guest enter the given @target power management suspension level. If @duration is non-zero, also schedule the guest to resume normal operation after that many seconds, if nothing else has resumed it earlier. Some hypervisors require that @duration be 0, for an indefinite suspension. Dependent on hypervisor used, this may require a guest agent to be available, e.g. QEMU. Beware that at least for QEMU, the domain's process will be terminated when VIR_NODE_SUSPEND_TARGET_DISK is used and a new process will be launched when libvirt is asked to wake up the domain. As a result of this, any runtime changes, such as device hotplug or memory settings, are lost unless such changes were made with VIR_DOMAIN_AFFECT_CONFIG flag.

`dom`: | a domain object
`target`: | a value from virNodeSuspendTarget
`duration`: | duration in seconds to suspend, or 0 for indefinite
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | 0 on success, -1 on failure.

### virDomainPMWakeup ()

    int	virDomainPMWakeup		(virDomainPtr dom,
    					 unsigned int flags)

Inject a wakeup into the guest that previously used virDomainPMSuspendForDuration, rather than waiting for the previously requested duration (if any) to elapse.

`dom`: | a domain object
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | 0 on success, -1 on failure.

### virDomainPinEmulator ()

    					 unsigned char * cpumap,
    					 int maplen,
    					 unsigned int flags)

Dynamically change the real CPUs which can be allocated to all emulator threads. This function may require privileged access to the hypervisor. @flags may include VIR_DOMAIN_AFFECT_LIVE or VIR_DOMAIN_AFFECT_CONFIG. Both flags may be set. If VIR_DOMAIN_AFFECT_LIVE is set, the change affects a running domain and may fail if domain is not alive. If VIR_DOMAIN_AFFECT_CONFIG is set, the change affects persistent state, and will fail for transient domains. If neither flag is specified (that is, @flags is VIR_DOMAIN_AFFECT_CURRENT), then an inactive domain modifies persistent setup, while an active domain is hypervisor-dependent on whether just live or both live and persistent state is changed. Not all hypervisors can support all flag combinations. See also virDomainGetEmulatorPinInfo for querying this information.

`domain`: | pointer to domain object, or NULL for Domain0
`cpumap`: | pointer to a bit map of real CPUs (in 8-bit bytes) (IN) Each bit set to 1 means that corresponding CPU is usable. Bytes are stored in little-endian order: CPU0-7, 8-15... In each byte, lowest CPU number is least significant bit.
`maplen`: | number of bytes in cpumap, from 1 up to size of CPU map in underlying virtualization system (Xen...). If maplen < size, missing bytes are set to zero. If maplen > size, failure code is returned.
`flags`: | bitwise-OR of virDomainModificationImpact
`Returns`: | 0 in case of success, -1 in case of failure.

    					 unsigned int iothread_id,
    					 unsigned char * cpumap,
    					 int maplen,
    					 unsigned int flags)

Dynamically change the real CPUs which can be allocated to an IOThread. This function may require privileged access to the hypervisor. @flags may include VIR_DOMAIN_AFFECT_LIVE or VIR_DOMAIN_AFFECT_CONFIG. Both flags may be set. If VIR_DOMAIN_AFFECT_LIVE is set, the change affects a running domain and may fail if domain is not alive. If VIR_DOMAIN_AFFECT_CONFIG is set, the change affects persistent state, and will fail for transient domains. If neither flag is specified (that is, @flags is VIR_DOMAIN_AFFECT_CURRENT), then an inactive domain modifies persistent setup, while an active domain is hypervisor-dependent on whether just live or both live and persistent state is changed.

`domain`: | pointer to domain object, or NULL for Domain0
`vcpu`: | virtual CPU number
`cpumap`: | pointer to a bit map of real CPUs (in 8-bit bytes) (IN) Each bit set to 1 means that corresponding CPU is usable. Bytes are stored in little-endian order: CPU0-7, 8-15... In each byte, lowest CPU number is least significant bit.

    					 unsigned char * cpumap,
    					 int maplen,
    					 unsigned int flags)

Dynamically change the real CPUs which can be allocated to a virtual CPU. This function may require privileged access to the hypervisor. @flags may include VIR_DOMAIN_AFFECT_LIVE or VIR_DOMAIN_AFFECT_CONFIG. Both flags may be set. If VIR_DOMAIN_AFFECT_LIVE is set, the change affects a running domain and may fail if domain is not alive.

`Returns`: | 0 in case of success, -1 in case of failure.

### virDomainReboot ()

    int	virDomainReboot			(virDomainPtr domain,
    					 unsigned int flags)

Reboot a domain, the domain object is still usable thereafter, but the domain OS is being stopped for a restart. Note that the guest OS may ignore the request. Additionally, the hypervisor may check and support the domain 'on_reboot' XML setting resulting in a domain that shuts down instead of rebooting. If @flags is set to zero, then the hypervisor will choose the method of shutdown it considers best. To have greater control pass one or more of the virDomainRebootFlagValues. The order in which the hypervisor tries each shutdown method is undefined, and a hypervisor is not required to support all methods. To use guest agent (VIR_DOMAIN_REBOOT_GUEST_AGENT) the domain XML must have <channel> configured. Due to implementation limitations in some drivers (the qemu driver, for instance) it is not advised to migrate or save a guest that is rebooting as a result of this API. Migrating such a guest can lead to a plain shutdown on the destination.

`domain`: | a domain object
`flags`: | bitwise-OR of virDomainRebootFlagValues
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainRef ()

    int	virDomainRef			(virDomainPtr domain)

Increment the reference count on the domain. For each additional call to this method, there shall be a corresponding call to virDomainFree to release the reference count, once the caller no longer needs the reference to this object. This method is typically useful for applications where multiple threads are using a connection, and it is required that the connection remain open until all threads have finished using it. ie, each new thread using a domain would increment the reference count.

`domain`: | the domain to hold a reference on
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainRename ()

    int	virDomainRename			(virDomainPtr dom,
    					 const char * new_name,
    					 unsigned int flags)

Rename a domain. New domain name is specified in the second argument. Depending on each driver implementation it may be required that domain is in a specific state. There might be some attributes and/or elements in domain XML that if no value provided at XML defining time, libvirt will derive their value from the domain name. These are not updated by this API. Users are strongly advised to change these after the rename was successful.

`dom`: | pointer to the domain object
`new_name`: | new domain name
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | 0 if successfully renamed, -1 on error

### virDomainReset ()

    int	virDomainReset			(virDomainPtr domain,
    					 unsigned int flags)

Reset a domain immediately without any guest OS shutdown. Reset emulates the power reset button on a machine, where all hardware sees the RST line set and reinitializes internal state. Note that there is a risk of data loss caused by reset without any guest OS shutdown.

`domain`: | a domain object
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainRestore ()

`conn`: | pointer to the hypervisor connection
`from`: | path to the input file
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainRestoreFlags ()

    int	virDomainRestoreFlags		(virConnectPtr conn,
    					 const char * from,
    					 const char * dxml,
    					 unsigned int flags)

This method will restore a domain saved to disk by virDomainSave(). If the hypervisor supports it, @dxml can be used to alter host-specific portions of the domain XML that will be used when restoring an image. For example, it is possible to alter the backing filename that is associated with a disk device, in order to prepare for file renaming done as part of backing up the disk device while the domain is stopped. If @flags includes VIR_DOMAIN_SAVE_BYPASS_CACHE, then libvirt will attempt to bypass the file system cache while restoring the file, or fail if it cannot do so for the given system; this can allow less pressure on file system cache, but also risks slowing restores from NFS. Normally, the saved state file will remember whether the domain was running or paused, and restore defaults to the same state. Specifying VIR_DOMAIN_SAVE_RUNNING or VIR_DOMAIN_SAVE_PAUSED in @flags will override the default read from the file. These two flags are mutually exclusive.

`conn`: | pointer to the hypervisor connection
`from`: | path to the input file
`dxml`: | (optional) XML config for adjusting guest xml used on restore
`flags`: | bitwise-OR of virDomainSaveRestoreFlags
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainResume ()

    int	virDomainResume			(virDomainPtr domain)

Resume a suspended domain, the process is restarted from the state where it was frozen by calling virDomainSuspend(). This function may require privileged access Moreover, resume may not be supported if domain is in some special state like VIR_DOMAIN_PMSUSPENDED.

`domain`: | a domain object
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainSave ()

    int	virDomainSave			(virDomainPtr domain,
    					 const char * to)

This method will suspend a domain and save its memory contents to a file on disk. After the call, if successful, the domain is not listed as running anymore (this ends the life of a transient domain). Use virDomainRestore() to restore a domain after saving. See virDomainSaveFlags() for more control. Also, a save file can be inspected or modified slightly with virDomainSaveImageGetXMLDesc() and virDomainSaveImageDefineXML().

`domain`: | a domain object
`to`: | path for the output file
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainSaveFlags ()

    int	virDomainSaveFlags		(virDomainPtr domain,
    					 const char * to,
    					 const char * dxml,
    					 unsigned int flags)

This method will suspend a domain and save its memory contents to a file on disk. After the call, if successful, the domain is not listed as running anymore (this ends the life of a transient domain). Use virDomainRestore() to restore a domain after saving. If the hypervisor supports it, @dxml can be used to alter host-specific portions of the domain XML that will be used when restoring an image. For example, it is possible to alter the backing filename that is associated with a disk device, in order to prepare for file renaming done as part of backing up the disk device while the domain is stopped. If @flags includes VIR_DOMAIN_SAVE_BYPASS_CACHE, then libvirt will attempt to bypass the file system cache while creating the file, or fail if it cannot do so for the given system; this can allow less pressure on file system cache, but also risks slowing saves to NFS. Normally, the saved state file will remember whether the domain was running or paused, and restore defaults to the same state. Specifying VIR_DOMAIN_SAVE_RUNNING or VIR_DOMAIN_SAVE_PAUSED in @flags will override what state gets saved into the file. These two flags are mutually exclusive. A save file can be inspected or modified slightly with virDomainSaveImageGetXMLDesc() and virDomainSaveImageDefineXML(). Some hypervisors may prevent this operation if there is a current block job running; in that case, use virDomainBlockJobAbort() to stop the block job first.

`domain`: | a domain object
`to`: | path for the output file
`dxml`: | (optional) XML config for adjusting guest xml used on restore
`flags`: | bitwise-OR of virDomainSaveRestoreFlags
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainSaveImageDefineXML ()

    int	virDomainSaveImageDefineXML	(virConnectPtr conn,
    					 const char * file,
    					 const char * dxml,
    					 unsigned int flags)

This updates the definition of a domain stored in a saved state file. @file must be a file created previously by virDomainSave() or virDomainSaveFlags(). @dxml can be used to alter host-specific portions of the domain XML that will be used when restoring an image. For example, it is possible to alter the backing filename that is associated with a disk device, to match renaming done as part of backing up the disk device while the domain is stopped. Normally, the saved state file will remember whether the domain was running or paused, and restore defaults to the same state. Specifying VIR_DOMAIN_SAVE_RUNNING or VIR_DOMAIN_SAVE_PAUSED in @flags will override the default saved into the file; omitting both leaves the file's default unchanged. These two flags are mutually exclusive.

`conn`: | pointer to the hypervisor connection
`file`: | path to saved state file
`dxml`: | XML config for adjusting guest xml used on restore
`flags`: | bitwise-OR of virDomainSaveRestoreFlags
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainSaveImageGetXMLDesc ()

    char *	virDomainSaveImageGetXMLDesc	(virConnectPtr conn,
    					 const char * file,
    					 unsigned int flags)

This method will extract the XML describing the domain at the time a saved state file was created. @file must be a file created previously by virDomainSave() or virDomainSaveFlags(). No security-sensitive data will be included unless @flags contains VIR_DOMAIN_SAVE_IMAGE_XML_SECURE.

`conn`: | pointer to the hypervisor connection
`file`: | path to saved state file
`flags`: | bitwise-OR of supported virDomainSaveImageXMLFlags
`Returns`: | a 0 terminated UTF-8 encoded XML instance, or NULL in case of error. The caller must free() the returned value.

### virDomainScreenshot ()

    char *	virDomainScreenshot		(virDomainPtr domain,
    					 virStreamPtr stream,
    					 unsigned int screen,
    					 unsigned int flags)

Take a screenshot of current domain console as a stream. The image format is hypervisor specific. Moreover, some hypervisors supports multiple displays per domain. These can be distinguished by @screen argument. This call sets up a stream; subsequent use of stream API is necessary to transfer actual data, determine how much data is successfully transferred, and detect any errors. The screen ID is the sequential number of screen. In case of multiple graphics cards, heads are enumerated before devices, e.g. having two graphics cards, both with four heads, screen ID 5 addresses the second head on the second card.

`domain`: | a domain object
`stream`: | stream to use as output
`screen`: | monitor ID to take screenshot from
`flags`: | extra flags; not used yet, so callers should always pass 0
`Returns`: | a string representing the mime-type of the image format, or NULL upon error. The caller must free() the returned value.

### virDomainSendKey ()

    int	virDomainSendKey		(virDomainPtr domain,

### virDomainSendProcessSignal ()

    int	virDomainSendProcessSignal	(virDomainPtr domain,
    					 long long pid_value,
    					 unsigned int signum,
    					 unsigned int flags)

Send a signal to the designated process in the guest The signal numbers must be taken from the virDomainProcessSignal enum. These will be translated to the corresponding signal number for the guest OS, by the guest agent delivering the signal. If there is no mapping from virDomainProcessSignal to the native OS signals, this API will report an error. If @pid_value is an integer greater than zero, it is treated as a process ID. If @pid_value is an integer less than zero, it is treated as a process group ID. All the @pid_value numbers are from the container/guest namespace. The value zero is not valid. Not all hypervisors will support sending signals to arbitrary processes or process groups. If this API is implemented the minimum requirement is to be able to use @pid_value == 1 (i.e. kill init). No other value is required to be supported. If the @signum is VIR_DOMAIN_PROCESS_SIGNAL_NOP then this API will simply report whether the process is running in the container/guest.

`domain`: | pointer to domain object
`pid_value`: | a positive integer process ID, or negative integer process group ID
`signum`: | a signal from the virDomainProcessSignal enum
`flags`: | currently unused, pass 0

    					 virTypedParameterPtr params,
    					 int nparams,
    					 unsigned int flags)

Change all or a subset of the per-device block IO tunables. The @disk parameter is either an unambiguous source name of the block device (the <source file='...'/> sub-element, such as "/path/to/image"), or the device target shorthand (the <target dev='...'/> sub-element, such as "xvda"). Valid names can be found by calling virDomainGetXMLDesc() and inspecting elements within //domain/devices/disk.

`dom`: | pointer to domain object
`disk`: | path to the block device, or device shorthand
`params`: | Pointer to blkio parameter objects
`nparams`: | Number of blkio parameters (this value can be the same or less than the number of parameters supported)

### virDomainSetBlockThreshold ()

    int	virDomainSetBlockThreshold	(virDomainPtr domain,
    					 const char * dev,
    					 unsigned long long threshold,
    					 unsigned int flags)

Set the threshold level for delivering the VIR_DOMAIN_EVENT_ID_BLOCK_THRESHOLD if the device or backing chain element described by @dev is written beyond the set threshold level. The threshold level is unset once the event fires. The event might not be delivered at all if libvirtd was not running at the moment when the threshold was reached. Hypervisors report the last written sector of an image in the bulk stats API (virConnectGetAllDomainStats/virDomainListGetStats) as "block.<num>.allocation" in the VIR_DOMAIN_STATS_BLOCK group. The current threshold value is reported as "block.<num>.threshold". This event allows to use thin-provisioned storage which needs management tools to grow it without the need for polling of the data.

`domain`: | pointer to domain object
`dev`: | string specifying the block device or backing chain element
`threshold`: | threshold in bytes when to fire the event
`flags`: | currently unused, callers should pass 0

    					 unsigned int flags)

Sets state of individual vcpus described by @cpumap via guest agent. Other vcpus are not modified. This API requires the VM to run. Various hypervisors or guest agent implementation may limit to operate on just 1 vCPU per call. @cpumap is a list of vCPU numbers. Its syntax is a comma separated list and a special markup using '-' and '^' (ex. '0-4', '0-3,^2'). The '-' denotes the range and the '^' denotes exclusive. The expression is sequentially evaluated, so "0-15,^8" is identical to "9-14,0-7,15" but not identical to "^8,0-15". Note that OSes (notably Linux) may require vCPU 0 to stay online to support low-level features a S3 sleep.

`domain`: | pointer to domain object
`cpumap`: | text representation of a bitmap of vcpus to set
`state`: | 0 to disable/1 to enable cpus described by @cpumap
`flags`: | currently unused, callers shall pass 0
`Returns`: | 0 on success, -1 on error.

    					 unsigned int iothread_id,
    					 virTypedParameterPtr params,
    					 int nparams,
    					 unsigned int flags)

Dynamically set IOThread parameters to the domain. It is left up to the underlying virtual hypervisor to determine the valid range for an @iothread_id, determining whether the @iothread_id already exists, and determining the validity of the provided param values. See VIR_DOMAIN_IOTHREAD_* for detailed description of accepted IOThread parameters. Since the purpose of this API is to dynamically modify the IOThread @flags should only include the VIR_DOMAIN_AFFECT_CURRENT and/or VIR_DOMAIN_AFFECT_LIVE virDomainMemoryModFlags. Setting other flags may cause errors from the hypervisor. Note that this call can fail if the underlying virtualization hypervisor does not support it or does not support setting the provided values.

Change a subset or all parameters of interface; currently this includes bandwidth parameters. The value of @flags should be either VIR_DOMAIN_AFFECT_CURRENT, or a bitwise-or of values VIR_DOMAIN_AFFECT_LIVE and VIR_DOMAIN_AFFECT_CONFIG, although hypervisors vary in which flags are supported. This function may require privileged access to the hypervisor.

    					 unsigned int type,
    					 unsigned int action,
    					 unsigned int flags)

Changes the actions of lifecycle events for domain represented as <on_$type>$action</on_$type> in the domain XML. QEMU driver has a limitation that if all lifecycle events are set to destroy when the domain is started, it's not possible to change any action for running domain.

`domain`: | pointer to domain object
`type`: | the lifecycle type from virDomainLifecycle
`action`: | the action type from virDomainLifecycleAction

    					 unsigned long memory)

Dynamically change the maximum amount of physical memory allocated to a domain. If domain is NULL, then this change the amount of memory reserved to Domain0 i.e. the domain where the application runs. This function may require privileged access to the hypervisor. This command is hypervisor-specific for whether active, persistent, or both configurations are changed; for more control, use virDomainSetMemoryFlags().

`domain`: | a domain object or NULL
`memory`: | the memory size in kibibytes (blocks of 1024 bytes)
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainSetMemory ()

    int	virDomainSetMemory		(virDomainPtr domain,
    					 unsigned long memory)

Dynamically change the target amount of physical memory allocated to a domain. If domain is NULL, then this change the amount of memory reserved to Domain0 i.e. the domain where the application runs. This function may require privileged access to the hypervisor. This command is hypervisor-specific for whether active, persistent, or both configurations are changed; for more control, use virDomainSetMemoryFlags().

`domain`: | a domain object or NULL
`memory`: | the memory size in kibibytes (blocks of 1024 bytes)

### virDomainSetMemoryFlags ()

    int	virDomainSetMemoryFlags		(virDomainPtr domain,
    					 unsigned long memory,
    					 unsigned int flags)

Dynamically change the target amount of physical memory allocated to a domain. If domain is NULL, then this change the amount of memory reserved to Domain0 i.e. the domain where the application runs. This function may require privileged access to the hypervisor. @flags may include VIR_DOMAIN_AFFECT_LIVE or VIR_DOMAIN_AFFECT_CONFIG. Both flags may be set. If VIR_DOMAIN_AFFECT_LIVE is set, the change affects a running domain and will fail if domain is not active. If VIR_DOMAIN_AFFECT_CONFIG is set, the change affects persistent state, and will fail for transient domains. If neither flag is specified (that is, @flags is VIR_DOMAIN_AFFECT_CURRENT), then an inactive domain modifies persistent setup, while an active domain is hypervisor-dependent on whether just live or both live and persistent state is changed. If VIR_DOMAIN_MEM_MAXIMUM is set, the change affects domain's maximum memory size rather than current memory size. Not all hypervisors can support all flag combinations.

`domain`: | a domain object or NULL
`memory`: | the memory size in kibibytes (blocks of 1024 bytes)
`flags`: | bitwise-OR of virDomainMemoryModFlags

    					 unsigned int flags)

Dynamically change the domain memory balloon driver statistics collection period. Use 0 to disable and a positive value to enable. @flags may include VIR_DOMAIN_AFFECT_LIVE or VIR_DOMAIN_AFFECT_CONFIG. Both flags may be set. If VIR_DOMAIN_AFFECT_LIVE is set, the change affects a running domain and will fail if domain is not active. If VIR_DOMAIN_AFFECT_CONFIG is set, the change affects persistent state, and will fail for transient domains. If neither flag is specified (that is, @flags is VIR_DOMAIN_AFFECT_CURRENT), then an inactive domain modifies persistent setup, while an active domain is hypervisor-dependent on whether just live or both live and persistent state is changed. Not all hypervisors can support all flag combinations.

`domain`: | a domain object or NULL
`period`: | the period in seconds for stats collection
`flags`: | bitwise-OR of virDomainMemoryModFlags
`Returns`: | 0 in case of success, -1 in case of failure.

### virDomainSetMetadata ()

    int	virDomainSetMetadata		(virDomainPtr domain,
    					 int type,
    					 const char * metadata,
    					 const char * key,
    					 const char * uri,
    					 unsigned int flags)

Sets the appropriate domain element given by @type to the value of @metadata. A @type of VIR_DOMAIN_METADATA_DESCRIPTION is free-form text; VIR_DOMAIN_METADATA_TITLE is free-form, but no newlines are permitted, and should be short (although the length is not enforced). For these two options @key and @uri are irrelevant and must be set to NULL. For type VIR_DOMAIN_METADATA_ELEMENT @metadata must be well-formed XML belonging to namespace defined by @uri with local name @key. Passing NULL for @metadata says to remove that element from the domain XML (passing the empty string leaves the element present). The resulting metadata will be present in virDomainGetXMLDesc(), as well as quick access through virDomainGetMetadata(). @flags controls whether the live domain, persistent configuration, or both will be modified.

`domain`: | a domain object
`type`: | type of metadata, from virDomainMetadataType
`metadata`: | new metadata text
`key`: | XML namespace key, or NULL
`uri`: | XML namespace URI, or NULL
`flags`: | bitwise-OR of virDomainModificationImpact
`Returns`: | 0 on success, -1 in case of failure.

### virDomainSetNumaParameters ()

    int	virDomainSetNumaParameters	(virDomainPtr domain,
    					 virTypedParameterPtr params,
    					 int nparams,
    					 unsigned int flags)

Change all or a subset of the numa tunables. This function may require privileged access to the hypervisor.

`domain`: | pointer to domain object
`params`: | pointer to numa parameter objects
`nparams`: | number of numa parameters (this value can be the same or less than the number of parameters supported)
`flags`: | bitwise-OR of virDomainModificationImpact
`Returns`: | -1 in case of error, 0 in case of success.

### virDomainSetPerfEvents ()

    int	virDomainSetPerfEvents		(virDomainPtr domain,
    					 virTypedParameterPtr params,
    					 int nparams,
    					 unsigned int flags)

Enable or disable the particular list of Linux perf events you care about. The @params argument should contain any subset of VIR_PERF_EVENT_ macros. Linux perf events are performance analyzing tool in Linux.

`domain`: | a domain object
`params`: | pointer to perf events parameter object
`nparams`: | number of perf event parameters (this value can be the same less than the number of parameters supported)
`flags`: | bitwise-OR of virDomainModificationImpact
`Returns`: | -1 in case of error, 0 in case of success.

### virDomainSetSchedulerParameters ()

    int	virDomainSetSchedulerParameters	(virDomainPtr domain,
    					 virTypedParameterPtr params,
    					 int nparams)

Change all or a subset or the scheduler parameters. It is hypervisor-specific whether this sets live, persistent, or both settings; for more control, use virDomainSetSchedulerParametersFlags.

`domain`: | pointer to domain object
`params`: | pointer to scheduler parameter objects
`nparams`: | number of scheduler parameter objects (this value can be the same or less than the returned value nparams of virDomainGetSchedulerType)
`Returns`: | -1 in case of error, 0 in case of success.

### virDomainSetSchedulerParametersFlags ()

    int	virDomainSetSchedulerParametersFlags	(virDomainPtr domain,
    						 virTypedParameterPtr params,
    						 int nparams,
    						 unsigned int flags)

Change a subset or all scheduler parameters. The value of @flags should be either VIR_DOMAIN_AFFECT_CURRENT, or a bitwise-or of values from VIR_DOMAIN_AFFECT_LIVE and VIR_DOMAIN_AFFECT_CURRENT, although hypervisors vary in which flags are supported.

`domain`: | pointer to domain object
`params`: | pointer to scheduler parameter objects
`nparams`: | number of scheduler parameter objects (this value can be the same or less than the returned value nparams of virDomainGetSchedulerType)
`flags`: | bitwise-OR of virDomainModificationImpact

### virDomainSetTime ()

    int	virDomainSetTime		(virDomainPtr dom,
    					 long long seconds,
    					 unsigned int nseconds,
    					 unsigned int flags)

When a domain is suspended or restored from a file the domain's OS has no idea that there was a big gap in the time. Depending on how long the gap was, NTP might not be able to resynchronize the guest. This API tries to set guest time to the given value. The time to set (@seconds and @nseconds) should be in seconds relative to the Epoch of 1970-01-01 00:00:00 in UTC. Please note that some hypervisors may require guest agent to be configured and running in order to be able to run this API.

`dom`: | a domain object
`seconds`: | time to set
`nseconds`: | the nanosecond part of @seconds
`flags`: | bitwise-OR of virDomainSetTimeFlags
`Returns`: | 0 on success, -1 otherwise.

### virDomainSetUserPassword ()

    int	virDomainSetUserPassword	(virDomainPtr dom,
    					 const char * user,
    					 const char * password,
    					 unsigned int flags)

Sets the @user password to the value specified by @password. If @flags contain VIR_DOMAIN_PASSWORD_ENCRYPTED, the password is assumed to be encrypted by the method required by the guest OS. Please note that some hypervisors may require guest agent to be configured and running in order to be able to run this API.

`dom`: | a domain object
`user`: | the username that will get a new password
`password`: | the password to set
`flags`: | bitwise-OR of virDomainSetUserPasswordFlags
`Returns`: | 0 on success, -1 otherwise.

### virDomainSetVcpu ()

    int	virDomainSetVcpu		(virDomainPtr domain,
    					 const char * vcpumap,
    					 int state,
    					 unsigned int flags)

Enables/disables individual vcpus described by @vcpumap in the hypervisor. Various hypervisor implementations may limit to operate on just 1 hotpluggable entity (which may contain multiple vCPUs on certain platforms). Note that OSes and hypervisors may require vCPU 0 to stay online.

`domain`: | pointer to domain object
`vcpumap`: | text representation of a bitmap of vcpus to set
`state`: | 0 to disable/1 to enable cpus described by @vcpumap
`flags`: | bitwise-OR of virDomainModificationImpact
`Returns`: | 0 on success, -1 on error.

### virDomainSetVcpus ()

    int	virDomainSetVcpus		(virDomainPtr domain,
    					 unsigned int nvcpus)

Dynamically change the number of virtual CPUs used by the domain. Note that this call may fail if the underlying virtualization hypervisor does not support it or if growing the number is arbitrarily limited. This function may require privileged access to the hypervisor. Note that if this call is executed before the guest has finished booting, the guest may fail to process the change. This command only changes the runtime configuration of the domain, so can only be called on an active domain. It is hypervisor-dependent whether it also affects persistent configuration; for more control, use virDomainSetVcpusFlags().

`domain`: | pointer to domain object, or NULL for Domain0
`nvcpus`: | the new number of virtual CPUs for this domain
`Returns`: | 0 in case of success, -1 in case of failure.

### virDomainSetVcpusFlags ()

    int	virDomainSetVcpusFlags		(virDomainPtr domain,
    					 unsigned int nvcpus,
    					 unsigned int flags)

Dynamically change the number of virtual CPUs used by the domain. Note that this call may fail if the underlying virtualization hypervisor does not support it or if growing the number is arbitrarily limited. This function may require privileged access to the hypervisor. @flags may include VIR_DOMAIN_AFFECT_LIVE to affect a running domain (which may fail if domain is not active), or VIR_DOMAIN_AFFECT_CONFIG to affect the next boot via the XML description of the domain. Both flags may be set. If neither flag is specified (that is, @flags is VIR_DOMAIN_AFFECT_CURRENT), then an inactive domain modifies persistent setup, while an active domain is hypervisor-dependent on whether just live or both live and persistent state is changed. Note that if this call is executed before the guest has finished booting, the guest may fail to process the change. If @flags includes VIR_DOMAIN_VCPU_MAXIMUM, then VIR_DOMAIN_AFFECT_LIVE must be clear, and only the maximum virtual CPU limit is altered; generally, this value must be less than or equal to virConnectGetMaxVcpus(). Otherwise, this call affects the current virtual CPU limit, which must be less than or equal to the maximum limit. Note that hypervisors may not allow changing the maximum vcpu count if processor topology is specified. If @flags includes VIR_DOMAIN_VCPU_GUEST, then the state of processors is modified inside the guest instead of the hypervisor. This flag can only be used with live guests and is incompatible with VIR_DOMAIN_VCPU_MAXIMUM. The usage of this flag may require a guest agent configured. Not all hypervisors can support all flag combinations.

`domain`: | pointer to domain object, or NULL for Domain0
`nvcpus`: | the new number of virtual CPUs for this domain, must be at least 1
`flags`: | bitwise-OR of virDomainVcpuFlags
`Returns`: | 0 in case of success, -1 in case of failure.

### virDomainShutdown ()

    int	virDomainShutdown		(virDomainPtr domain)

Shutdown a domain, the domain object is still usable thereafter, but the domain OS is being stopped. Note that the guest OS may ignore the request. Additionally, the hypervisor may check and support the domain 'on_poweroff' XML setting resulting in a domain that reboots instead of shutting down. For guests that react to a shutdown request, the differences from virDomainDestroy() are that the guests disk storage will be in a stable state rather than having the (virtual) power cord pulled, and this command returns as soon as the shutdown request is issued rather than blocking until the guest is no longer running. If the domain is transient and has any snapshot metadata (see virDomainSnapshotNum()), then that metadata will automatically be deleted when the domain quits.

`domain`: | a domain object
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainShutdownFlags ()

    int	virDomainShutdownFlags		(virDomainPtr domain,
    					 unsigned int flags)

Shutdown a domain, the domain object is still usable thereafter but the domain OS is being stopped. Note that the guest OS may ignore the request. Additionally, the hypervisor may check and support the domain 'on_poweroff' XML setting resulting in a domain that reboots instead of shutting down. For guests that react to a shutdown request, the differences from virDomainDestroy() are that the guest's disk storage will be in a stable state rather than having the (virtual) power cord pulled, and this command returns as soon as the shutdown request is issued rather than blocking until the guest is no longer running. If the domain is transient and has any snapshot metadata (see virDomainSnapshotNum()), then that metadata will automatically be deleted when the domain quits. If @flags is set to zero, then the hypervisor will choose the method of shutdown it considers best. To have greater control pass one or more of the virDomainShutdownFlagValues. The order in which the hypervisor tries each shutdown method is undefined, and a hypervisor is not required to support all methods. To use guest agent (VIR_DOMAIN_SHUTDOWN_GUEST_AGENT) the domain XML must have <channel> configured.

`domain`: | a domain object
`flags`: | bitwise-OR of virDomainShutdownFlagValues
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainStatsRecordListFree ()

    void	virDomainStatsRecordListFree	(virDomainStatsRecordPtr * stats)

Convenience function to free a list of domain stats returned by virDomainListGetStats and virConnectGetAllDomainStats.

`stats`: | NULL terminated array of virDomainStatsRecords to free

### virDomainSuspend ()

    int	virDomainSuspend		(virDomainPtr domain)

Suspends an active domain, the process is frozen without further access to CPU resources and I/O but the memory used by the domain at the hypervisor level will stay allocated. Use virDomainResume() to reactivate the domain. This function may require privileged access. Moreover, suspend may not be supported if domain is in some special state like VIR_DOMAIN_PMSUSPENDED.

`domain`: | a domain object
`Returns`: | 0 in case of success and -1 in case of failure.

### virDomainUndefine ()

    int	virDomainUndefine		(virDomainPtr domain)

Undefine a domain. If the domain is running, it's converted to transient domain, without stopping it. If the domain is inactive, the domain configuration is removed. If the domain has a managed save image (see virDomainHasManagedSaveImage()), or if it is inactive and has any snapshot metadata (see virDomainSnapshotNum()), then the undefine will fail. See virDomainUndefineFlags() for more control.

`domain`: | pointer to a defined domain
`Returns`: | 0 in case of success, -1 in case of error

### virDomainUndefineFlags ()

    int	virDomainUndefineFlags		(virDomainPtr domain,
    					 unsigned int flags)

Undefine a domain. If the domain is running, it's converted to transient domain, without stopping it. If the domain is inactive, the domain configuration is removed. If the domain has a managed save image (see virDomainHasManagedSaveImage()), then including VIR_DOMAIN_UNDEFINE_MANAGED_SAVE in @flags will also remove that file, and omitting the flag will cause the undefine process to fail. If the domain is inactive and has any snapshot metadata (see virDomainSnapshotNum()), then including VIR_DOMAIN_UNDEFINE_SNAPSHOTS_METADATA in @flags will also remove that metadata. Omitting the flag will cause the undefine of an inactive domain to fail. Active snapshots will retain snapshot metadata until the (now-transient) domain halts, regardless of whether this flag is present. On hypervisors where snapshots do not use libvirt metadata, this flag has no effect. If the domain has any nvram specified, the undefine process will fail unless VIR_DOMAIN_UNDEFINE_KEEP_NVRAM is specified, or if VIR_DOMAIN_UNDEFINE_NVRAM is specified to remove the nvram file.

`domain`: | pointer to a defined domain
`flags`: | bitwise-OR of supported virDomainUndefineFlagsValues
`Returns`: | 0 in case of success, -1 in case of error

### virDomainUpdateDeviceFlags ()

    int	virDomainUpdateDeviceFlags	(virDomainPtr domain,
    					 const char * xml,
    					 unsigned int flags)

Change a virtual device on a domain, using the flags parameter to control how the device is changed. VIR_DOMAIN_AFFECT_CURRENT specifies that the device change is made based on current domain state. VIR_DOMAIN_AFFECT_LIVE specifies that the device shall be changed on the active domain instance only and is not added to the persisted domain configuration. VIR_DOMAIN_AFFECT_CONFIG specifies that the device shall be changed on the persisted domain configuration only. Note that the target hypervisor must return an error if unable to satisfy flags. E.g. the hypervisor driver will return failure if LIVE is specified but it only supports modifying the persisted device allocation. This method is used for actions such changing CDROM/Floppy device media, altering the graphics configuration such as password, reconfiguring the NIC device backend connectivity, etc. The supplied XML description of the device should contain all the information that is found in the corresponding domain XML. Leaving out any piece of information may be treated as a request for its removal, which may be denied. For instance, when users want to change CDROM media only for live XML, they must provide live disk XML as found in the corresponding live domain XML with only the disk path changed.

`domain`: | pointer to domain object
`xml`: | pointer to XML description of one device
`flags`: | bitwise-OR of virDomainDeviceModifyFlags
`Returns`: | 0 in case of success, -1 in case of failure.
