Detailed Description

The Move-SCVirtualMachine cmdlet moves a virtual machine stored in the Virtual Machine Manager (VMM) library or deployed on a host to a new location on a host.

In System Center 2012 Service Pack 1 (SP1), you can take advantage of new migration capabilities included in Windows Server 2012, such as live migration of virtual machines between two stand-alone computers, or live migration between stand-alone computers and a cluster node. Additionally, multiple concurrent live migrations are supported. For more information about migrating virtual machines in , see Migrating Virtual Machines and Storage in VMM in the TechNet Library at https://technet.microsoft.com/ library/jj860420.aspx.

Note: If you move a virtual machine deployed on a host running Windows Server 2008 R2 to a host running Windows Server 2012, you cannot move the virtual machine back to a host running Windows Server 2008 R2.

VMM includes storage migration features that let you move one or more virtual hard disks of a running virtual machine to a new location. You can use the Move-SCVirtualMachine cmdlet with the Move-SCVirtualHardDisk cmdlet to move Windows-based virtual hard disk (.vhd) files and VMware-based virtual hard disk (.vmdk) files to a location on a different host. You can also use the Move-SCVirtualHardDisk cmdlet to move a .vhd file or a .vmdk file from one location to another on the same host.

Note: To move a virtual machine from a host and store it in the library, you must use the Save-SCVirtualMachine cmdlet.

VMM can use any of the following transfer methods, listed in the order in which VMM tries to use them:

-- Hyper-V Live Migration. If a virtual machine is running and is deployed on a Hyper-V host that is a node of a Windows Server 2008 R2 or Windows Server 2012 host cluster, by default, VMM will use Hyper-V Live Migration to move the virtual machine to another node in the cluster without any disruption of service, for example, moving a running virtual machine will not disconnect it from the network. Additionally, the virtual machine will retain its high availablility attribute on the virtual machine. You do not need to specify a path for this type of move. You can start live migration of multiple virtual machines at the same time.

-- Windows Server 2008 Cluster Migration. System Center 2012 continues to support Windows 2008 Cluster Migration. This is sometimes called quick migration. Cluster migration lets you move a running virtual machine on a Hyper-V node of a host cluster. It also lets you move a virtual machine that is in a stopped or saved state and that is deployed to another node in the cluster. You can use cluster migration to move a virtual machine in a stopped or saved state if the virtual machine is deployed on either of the following nodes:

---- A node in a Windows Server 2008 cluster
---- A node in a Windows Server 2008 R2 cluster

You do not need to specify a path for this type of move. Windows Server 2008 cluster migration places the virtual machine in a saved state during migration, which causes a temporary loss of service to any users of that virtual machine.

-- VMware live migration. If a virtual machine deployed on a VMware ESX host uses shared storage, VMM can use the VMware live migration feature VMware VMotion to move the virtual machine to a new host.

You do not need to specify a path for this type of move. The Move-SCVirtualMachine cmdlet can use VMware VMotion to move a virtual machine from one ESX host to another only if both ESX hosts are in the same Datacenter container on the vCenter Server.

-- Citrix XenServer XenMotion. If a virtual machine deployed on a Citrix XenServer host uses shared storage and is part of the same resource pool, VMM can use the XenServer live migration feature (Citrix XenMotion) to move the virtual machine to a new host.

You do not need to specify a path for this type of move. The Move-SCVirtualMachine cmdlet can use Citrix XenMotion to move a virtual machine from one XenServer host to another only if both XenServer hosts are in the same resource pool.

This is the only supported method for moving a virtual machine directly between XenServer hosts in VMM.

-- SAN migration (Fibre Channel, iSCSI, or NPIV). If the virtual machine is on a host that is connected to a SAN and the virtual machine is on a SAN LUN, VMM can move that virtual machine to another host if that host has access to the same SAN. In a SAN transfer, the target LUNs are redirected from the source host to the destination host, but no files are moved, which is why a SAN transfer is much faster than moving virtual machine files from one host to another over a local area network (LAN).

VMM supports SAN migration of virtual machines into and out of a cluster.

You must specify a path for this type of move. VMM can use an NPIV SAN transfer if a host bus adapter (HBA) with NPIV support is available.

-- Network migration. If no faster method is available, VMM uses a network transfer to move the virtual machine files from one host to another over the LAN that connects the two hosts. You can choose to use this transfer type even if the SAN transfer type is available. You must specify a path for this type of move.

When more than one transfer type is available, the Move-SCVirtualMachine cmdlet automatically uses the fastest available transfer type to move a virtual machine. If the first method is not appropriate or available for the virtual machine you want to move, VMM tries to use the next method, and so on. If you want to force the use of a network transfer, specify the UseLAN parameter.

Parameters

-BlockLiveMigrationIfHostBusy

Indicates that this cmdlet blocks retrying a Hyper-V live migration if the migration failed because the source host or the destination host is already participating in another live migration.

-DiscardSavedState

Deletes the saved state associated with a virtual machine or service.

-HighlyAvailable<Boolean>

Indicates whether a virtual machine will be placed on a Hyper-V host that is part of a host cluster. Configure this setting on a virtual machine, or on a template or hardware profile that you use to create virtual machines.

-JobGroup<Guid]>

Specifies an identifier for a series of commands that will run as a set just before the final command that includes the same job group identifier runs.

-JobVariable<String>

Specifies that job progress is tracked and stored in the variable named by this parameter.

-OnBehalfOfUser<System.String>

-OnBehalfOfUserRole<Microsoft.SystemCenter.VirtualMachineManager.UserRole>

Examples

Example 1: Move a virtual machine from the library to a host

The first command gets the virtual machine object named VM01, which is currently stored in the VMM library on the library server named LibServer01, and stores the object in the $VM variable. This example assumes that only one virtual machine named VM01 is currently stored on LibServer01, and that, therefore, Get-SCVirtualMachine retrieves only one object.

The second command gets the host object named VMHost01, and then stores the object in the $VMHost variable.

The last command moves the virtual machine from its current location in the library to the location D:\VirtualMachinePath on the host stored in $VMHost. The command automatically uses the fastest available transfer type. When the command completes, it returns information about the moved virtual machine.

PS C:\> $VM = Get-SCVirtualMachine | where { $_.Name -eq "VM01" -and $_.LibraryServer -eq "LibServer01.Contoso.com" }
PS C:\> $VMHost = Get-SCVMHost -ComputerName "VMHost01.Contoso.com"
PS C:\> Move-SCVirtualMachine -VMHost $VMHost -VM $VM -Path "D:\VirtualMachinePath"

Example 2: Move a virtual machine from the library to a host asynchronously

The first two commands in this example are identical to the commands in example 1, except for the name of the virtual machine host.

When the third command moves the virtual machine from its current location to D:\VirtualMachinePath on VMHost02, it uses the RunAsynchronously parameter to return control to the command shell immediately, and the JobVariable parameter to track the progress of the job. JobVariable stores a record of the job progress in the $MoveVMJob variable. For the JobVariable parameter, you do not use the dollar sign ($) when the variable is created.

The last command displays the contents of $MoveVMJob, which includes a description of the move job, its status, its progress, and other information.

PS C:\> $VM = Get-SCVirtualMachine | where { $_.Name -eq "VM01" -and $_.LibraryServer -eq "LibServer01.Contoso.com" }
PS C:\> $VMHost = Get-SCVMHost -ComputerName "VMHost02.Contoso.com"
PS C:\> Move-SCVirtualMachine -VMHost $VMHost -VM $VM -Path "D:\VirtualMachinePath" -RunAsynchronously -JobVariable "MoveVMJob"
PS C:\> $MoveVMJob

Example Example 3: Move a virtual machine from the library to a host by forcing a LAN transfer.

The first command gets the virtual machine object named VM03 on library server LibServer01, and then stores the object in the $VM variable.

The second command gets the host object named VMHost03 and stores the object in the $VMHost variable.

The last command moves the virtual machine VM03 from its current location in the library to D:\VirtualMachinePath on VMHost03 using the UseLAN parameter to specify that the transfer use a network transfer even if faster transfer mechanisms are available.

PS C:\> $VM = Get-SCVirtualMachine | where { $_.Name -eq "VM03" -and $_.LibraryServer -eq "LibServer01.Contoso.com" }
PS C:\> $VMHost = Get-SCVMHost -ComputerName "VMHost03.Contoso.com"
PS C:\> Move-SCVirtualMachine -VMHost $VMHost -VM $VM -Path "D:\VirtualMachinePath" -UseLAN

Example Example 4: Move a virtual machine between hosts by using VMware VMotion.

The first gets the virtual machine object named VM04 on ESXHost01, and then stores the object in the $VM variable.

The second command gets the ESX host object named ESXHost02, and then stores the object in the $VMHost variable.

In the last command, the Move-SCVirtualMachine cmdlet uses VMware VMotion to move the virtual machine from its current ESX host to the other ESX host.

Note: The Move-SCVirtualMachine cmdlet can use the VMware VMotion feature to move a virtual machine from one ESX host to another only if both ESX servers are in the same Datacenter container on the vCenter Server.

PS C:\> $VM = Get-SCVirtualMachine -Name "VM04" | where {$_.VMHost.Name -eq "ESXHost01"}
PS C:\> $VMHost = Get-SCVMHost | where {$_.Name -eq "ESXHost02"}
PS C:\> Move-SCVirtualMachine -VM $VM -VMHost $VMHost -Path "[Storage2]" 

Example 5: Move a highly available virtual machine between nodes in a host cluster by using Hyper-V live migration

The first command gets the virtual machine object named HAVM05 on VMHVHostNode05A, and then stores the object in the $VM variable. This example assumes that HAVM05 is a highly available virtual machine and that VMHVHostNode05A and VMHVHostNode05B are nodes in a Hyper-V host cluster.

The second command gets the host object named VMHVHostNode05B, and then stores the object in the $VMHost variable.

In the last command, the Move-SCVirtualMachine cmdlet uses live migration to move the virtual machine from VMHVHostNode05A to VMHVHostNode05B.

PS C:\> $VM = Get-SCVirtualMachine -Name "HAVM05" | where {$_.VMHost.Name -eq "VMHVHostNode05A.Contoso.com"}
PS C:\> $VMHost = Get-SCVMHost | where {$_.Name -eq "VMHVHostNode05B.Contoso.com"}
PS C:\> Move-SCVirtualMachine -VM $VM -VMHost $VMHost -Path "D:\VMs\"

Example Example 6: Move a running virtual machine on a Hyper-V host to a new location on the same host.

The first command stores the string E:\VHDs in $MoveVhdPath. This is the path to which you want to move the virtual hard disk of the virtual machine.

The second command gets the virtual machine object named VM06, and then stores the object the $VM variable.

The third command gets the host object named VMHost06, and then stores the object in the $VMHost variable. This example assumes that VMHost06 is a Hyper-V host.

The fourth command stores the string E:\VirtualMachinePath in the $HostPath variable. This is the path to which you want to move VM06.

The fifth command creates a GUID string, and then stores it in the $JobGroupID variable. This GUID is a job group ID that functions as an identifier that groups subsequent commands that include this identifier into a single job group.

The sixth command sets the virtual hard disk path to the value stored in $MoveVhdPath and it connects the virtual hard disk to Bus 1 and LUN 1 on the virtual IDE controller on the virtual machine. This command uses the JobGroup parameter to specify that it does not actually run until the Move-SCVirtualMachine cmdlet triggers the running of any commands in the JobGroup list.

The last command runs any commands that contain $JobGroupID, in this case, Move-SCVirtualHardDisk, and it runs Move-SCVirtualMachine. As a result, VM06, a running virtual machine, is moved from its current location to E:\VirtualMachinePath on the same host. The virtual machine's virtual hard disk is moved to E:\VHDs.

Note: You can also move a running virtual machine from one Hyper-V host to another Hyper-V host.

PS C:\> $MoveVhdPath = "E:\VHDs"
PS C:\> $VM = Get-SCVirtualMachine "VM06"
PS C:\> $VMHost = Get-SCVMHost "VMHost06"
PS C:\> $HostPath = "E:\VirtualMachinePath"
PS C:\> $JobGroupID = [System.Guid]::NewGuid().ToString()
PS C:\> Move-SCVirtualHardDisk -IDE -Bus 1 -Lun 1 -Path $MoveVhdPath -JobGroup $JobGroupID
PS C:\> Move-SCVirtualMachine -VM $VM -VMHost $VMHost -Path $HostPath -JobGroup $JobGroupID
