Returns an error if the VM could not boot on this host for some reason

Parameters:	session ref session_id	Reference to a valid session
	VM ref self	The VM
	host ref host	The host
Minimum role:	read-only
Errors:	HOST_NOT_ENOUGH_FREE_MEMORY	Not enough server memory is available to perform this operation.
	HOST_NOT_ENOUGH_PCPUS	The host does not have enough pCPUs to run the VM. It needs at least as many as the VM has vCPUs.
	NETWORK_SRIOV_INSUFFICIENT_CAPACITY	There is insufficient capacity for VF reservation
	HOST_NOT_LIVE	This operation cannot be completed as the server is not live.
	HOST_DISABLED	The specified server is disabled.
	HOST_CANNOT_ATTACH_NETWORK	Server cannot attach network (in the case of NIC bonding, this may be because attaching the network on this server would require other networks - that are currently active - to be taken down).
	VM_HVM_REQUIRED	HVM is required for this operation
	VM_REQUIRES_GPU	You attempted to run a VM on a host which doesn't have a pGPU available in the GPU group needed by the VM. The VM has a vGPU attached to this GPU group.
	VM_REQUIRES_IOMMU	You attempted to run a VM on a host which doesn't have I/O virtualization (IOMMU/VT-d) enabled, which is needed by the VM.
	VM_REQUIRES_NETWORK	You attempted to run a VM on a host which doesn't have a PIF on a Network needed by the VM. The VM has at least one VIF attached to the Network.
	VM_REQUIRES_SR	You attempted to run a VM on a host which doesn't have access to an SR needed by the VM. The VM has at least one VBD attached to a VDI in the SR.
	VM_REQUIRES_VGPU	You attempted to run a VM on a host on which the vGPU required by the VM cannot be allocated on any pGPUs in the GPU_group needed by the VM.
	VM_HOST_INCOMPATIBLE_VERSION	This VM operation cannot be performed on an older-versioned host during an upgrade.
	VM_HOST_INCOMPATIBLE_VIRTUAL_HARDWARE_PLATFORM_VERSION	You attempted to run a VM on a host that cannot provide the VM's required Virtual Hardware Platform version.
	INVALID_VALUE	The value given is invalid
	MEMORY_CONSTRAINT_VIOLATION	The dynamic memory range does not satisfy the following constraint.
	OPERATION_NOT_ALLOWED	You attempted an operation that was not allowed.
	VALUE_NOT_SUPPORTED	You attempted to set a value that is not supported by this implementation. The fully-qualified field name and the value that you tried to set are returned. Also returned is a developer-only diagnostic reason.
	VM_INCOMPATIBLE_WITH_THIS_HOST	The VM is incompatible with the CPU features of this host.
Published in:	XenServer 4.0 (rio)
Changed in:	Citrix Hypervisor 8.1 (quebec)	Does additional compatibility checks when VM powerstate is not halted (e.g. CPUID). Use this before calling VM.resume or VM.pool_migrate.

void clean_shutdown (session ref, VM ref)

VM ref clone (session ref, VM ref, string)

int compute_memory_overhead (session ref, VM ref)

VM ref copy (session ref, VM ref, string, SR ref)

Copied the specified VM, making a new VM. Unlike clone, copy does not exploits the capabilities of the underlying storage repository in which the VM's disk images are stored. Instead, copy guarantees that the disk images of the newly created VM will be 'full disks' - i.e. not part of a CoW chain. This function can only be called when the VM is in the Halted State.

Parameters:	session ref session_id	Reference to a valid session
	VM ref vm	The VM to be copied
	string new_name	The name of the copied VM
	SR ref sr	An SR to copy all the VM's disks into (if an invalid reference then it uses the existing SRs)
Minimum role:	vm-admin
Result:	The reference of the newly created VM.
Errors:	VM_BAD_POWER_STATE	You attempted an operation on a VM that was not in an appropriate power state at the time; for example, you attempted to start a VM that was already running. The parameters returned are the VM's handle, and the expected and actual VM state at the time of the call.
	SR_FULL	The SR is full. Requested new size exceeds the maximum size
	OPERATION_NOT_ALLOWED	You attempted an operation that was not allowed.
	LICENCE_RESTRICTION	This operation is not allowed because your license lacks a needed feature. Please contact your support representative.
Published in:	XenServer 4.0 (rio)	Copies a VM to an SR. There must be a host that can see both the source and destination SRs simultaneously
Extended in:	XenServer 5.6 FP1 (cowley)	The copy can now be performed between any two SRs.

void copy_bios_strings (session ref, VM ref, host ref)

VM ref create (session ref, VM record)

NOT RECOMMENDED! VM.clone or VM.copy (or VM.import) is a better choice in almost all situations. The standard way to obtain a new VM is to call VM.clone on a template VM, then call VM.provision on the new clone. Caution: if VM.create is used and then the new VM is attached to a virtual disc that has an operating system already installed, then there is no guarantee that the operating system will boot and run. Any software that calls VM.create on a future version of this API may fail or give unexpected results. For example this could happen if an additional parameter were added to VM.create. VM.create is intended only for use in the automatic creation of the system VM templates. It creates a new VM instance, and returns its handle. The constructor args are: name_label, name_description, power_state, user_version*, is_a_template*, suspend_VDI, affinity*, memory_target, memory_static_max*, memory_dynamic_max*, memory_dynamic_min*, memory_static_min*, VCPUs_params*, VCPUs_max*, VCPUs_at_startup*, actions_after_softreboot, actions_after_shutdown*, actions_after_reboot*, actions_after_crash*, PV_bootloader*, PV_kernel*, PV_ramdisk*, PV_args*, PV_bootloader_args*, PV_legacy_args*, HVM_boot_policy*, HVM_boot_params*, HVM_shadow_multiplier, platform*, PCI_bus*, other_config*, last_boot_CPU_flags, last_booted_record, recommendations*, xenstore_data, ha_always_run, ha_restart_priority, tags, blocked_operations, protection_policy, is_snapshot_from_vmpp, snapshot_schedule, is_vmss_snapshot, appliance, start_delay, shutdown_delay, order, suspend_SR, version, generation_id, hardware_platform_version, has_vendor_device, reference_label, domain_type, NVRAM (* = non-optional).

Parameters:	session ref session_id	Reference to a valid session
	VM record args	All constructor arguments
Minimum role:	vm-admin
Result:	reference to the newly created object
Published in:	XenServer 4.0 (rio)
Changed in:	XAPI 1.257.0 (1.257.0)	possibility to create a VM in suspended mode with a suspend_VDI set

VM ref snapshot_with_quiesce (session ref, VM ref, string)

Snapshots the specified VM with quiesce, making a new VM. Snapshot automatically exploits the capabilities of the underlying storage repository in which the VM's disk images are stored (e.g. Copy on Write).

Parameters:	session ref session_id	Reference to a valid session
	VM ref vm	The VM to be snapshotted
	string new_name	The name of the snapshotted VM
Minimum role:	vm-power-admin
Result:	The reference of the newly created VM.
Errors:	VM_BAD_POWER_STATE	You attempted an operation on a VM that was not in an appropriate power state at the time; for example, you attempted to start a VM that was already running. The parameters returned are the VM's handle, and the expected and actual VM state at the time of the call.
	SR_FULL	The SR is full. Requested new size exceeds the maximum size
	OPERATION_NOT_ALLOWED	You attempted an operation that was not allowed.
	VM_SNAPSHOT_WITH_QUIESCE_FAILED	The quiesced-snapshot operation failed for an unexpected reason
	VM_SNAPSHOT_WITH_QUIESCE_TIMEOUT	The VSS plug-in has timed out
	VM_SNAPSHOT_WITH_QUIESCE_PLUGIN_DEOS_NOT_RESPOND	The VSS plug-in cannot be contacted
	VM_SNAPSHOT_WITH_QUIESCE_NOT_SUPPORTED	The VSS plug-in is not installed on this virtual machine

void start (session ref, VM ref, bool, bool)

Start the specified VM. This function can only be called with the VM is in the Halted State.
