Detailed Description

The Set-SCVirtualMachine cmdlet changes one or more properties of a virtual machine managed by System Center Virtual Machine Manager (VMM). Properties that you can change include the following:

- Name, owner, and description of a virtual machine.

- BIOS boot order (if deployed on a Hyper-V host).

- Amount of resources on the host used by a virtual machine. These include:

- Maximum amount of host CPU resources that a virtual machine can use.

- Expected use of host CPU by a virtual machine.

- Amount of host CPU resources used by one virtual machine relative to

other virtual machines on the same host.

- Amount of host memory that a virtual machine can use.

- Amount of bandwidth on the host's network that a virtual machine can use.

- Hardware settings for a virtual machine unrelated to host resources. These include:

- Number of CPUs.

- Type of CPU.

- Number of disk input/output operations per second (IOPS).

- Limiting CPU functionality (for an older operating system,

such as Windows NT 4.0).

- Cost center, tag, and custom settings used to filter virtual machines by criteria.

- Settings that enable various optional capabilities, including:

- Enabling or disabling a library object to make it available,

or temporarily unavailable, to users.

- Enabling backing up a virtual machine on a Hyper-V host with Volume Shadow Copy

service.

- Enabling a key/value pair for data exchange between a virtual machine and its

Hyper-V host.

- Enabling shutdown of a virtual machine from the Hyper-V console.

- Enabling time synchronization between a virtual machine and its Hyper-V host.

- Enabling the BIOS value for NumLock for a virtual machine on a Hyper-V host.

- Setting that identifies whether a virtual machine is highly available, that is,

a virtual machine to be deployed on a node of a Hyper-V host cluster or a Citrix

XenServer host cluster.

- Setting that determines whether virtualization guest services are

installed on a virtual machine deployed on a Hyper-V host.

- Number of seconds to delay before starting a virtual machine.

- Setting that identifies the operating system used for a virtual machine.

- Start and stop actions for a virtual machine.

- Setting that limits the number of virtual machines self-service users can create.

- Setting used to switch the role that a self-service user who belongs

to multiple roles uses to manage a virtual machine.

- Setting that assigns a virtual machine on an ESX host to a VMware resource pool.

If you want to change the properties of a virtual floppy drive, virtual DVD drive, virtual network adapter, or virtual SCSI adapter associated with a specific virtual machine, use the Set-SCVirtualFloppyDrive, Set-SCVirtualDVDDrive, Set-SCVirtualNetworkAdapter, or Set-SCVirtualScsiAdapter cmdlets, respectively.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see about_CommonParameters.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

Outputs

The output type is the type of the objects that the cmdlet emits.

  • VirtualMachine

Notes

  • Requires a VMM virtual machine object, which can be retrieved by using the Get-SCVirtualMachine cmdlet.

Examples

1: Specify an amount of memory for an existing virtual machine.

The first command gets the virtual machine object named VM01 and stores the object in the $VM variable.

The second determines whether the virtual machine stored in $VM is in a powered off state. If the virtual machine is not in a powered off state, the command uses the Stop-SCVirtualMachine command to power off the virtual machine. For more information about powering off a virtual machine, type: "Get-Help Stop-SCVirtualMachine -detailed".

The last command changes the memory allocated to VM01 to 1024 MB.


PS C:\> $VM = Get-SCVirtualMachine -Name "VM01"PS C:\> if($VM.Status -ne "PowerOff"){Stop-SCVirtualMachine -VM $VM}PS C:\> Set-SCVirtualMachine -VM $VM -MemoryMB 1024

2: Change the user role used to manage a virtual machine for a user who belongs to multiple self-service user roles.

The first command gets the virtual machine object named VM02 from VMMServer01 and stores the object in the $VM variable.

The second command gets the user role object named ContosoSelfServiceUsers and stores the object in the $SSRole variable.

The last command specifies that members of the self-service user role called SSUserRole3 are now granted the permission to manage the VM called VM02.

NOTE: VMM uses the UserRole parameter to set which virtual machines are managed by the members of a specific self-service user role. Typically, you do not need to use the Set-SCVirtualMachine cmdlet with the UserRole parameter to configure this setting. However, if one or more users are members of multiple self-service user roles and you grant them permission to manage multiple virtual machines on the same host, you might encounter a case where you want to switch which user role is authorized to manage a particular virtual machine. This example illustrates that scenario.


PS C:\> $VM = Get-SCVirtualMachine -VMMServer "VMMServer01.Contoso.com" -Name "VM02"PS C:\> $SSRole = Get-SCUserRole -Name "ContosoSelfServiceUsers"PS C:\> Set-SCVirtualMachine -VM $VM -UserRole $SSRole

3. Disable time syncronization on a virtual machine used as a domain controller.

The first command stores the current setting for $ErrorActionPreference in variable $EAP. This variable will be used later to return the setting to its original value.

The second command sets the action preference to STOP. This error action preference changes an error from a non-terminating error to a terminating error. The error object is thrown as an exception instead of being written to the output pipe, and the command does not continue to run.

The third command gets the virtual machine object named VM03 and stores the object in the $VM variable.

The fourth command disables the time syncronization setting. Typically, disabling time synchronization is required for virtual machines that act as domain controllers. The command uses the trap statement to catch terminating exceptions. If the Set-SCVirtualMachine command fails, the string in the trap statement is displayed. Continue is used in the trap statement to continue running instead of exiting. The Out-Null cmdlet redirects the output to $Null instead of sending it to the console.

The last command sets the value for $ErrorActionPreference to the value stored in $EAP.


PS C:\> $EAP = $ErrorActionPreferencePS C:\> $ErrorActionPreference = "STOP"PS C:\> $VM = Get-SCVirtualMachine -Name "VM03"PS C:\> trap{"Fail: Cannot disable Time Synchronization for VM: $VM";continue} Set-SCVirtualMachine -VM $VM -EnableTimeSynchronization $TRUE | Out-NullPS C:\> $ErrorActionPreference = $EAP

4. Set the device boot order for all virtual machines that support this feature.

The first command stores the current setting for $ErrorActionPreference in $EAP. This variable will be used later to return the setting to its original value.

The second command sets the error action preference to Stop. This error action preference changes an error from a non-terminating error to a terminating error. The error object is thrown as an exception instead of being written to the output pipe, and the command does not continue to run.

The third command gets each virtual machine object stores the objects in $VMs. Using the '@' symbol and parentheses ensures that the command stores the results in an array in case the command returns a single object or a null value.

The fourth command sets the BIOS boot order for each virtual machine to PXEBoot,IDEHarddrive,CD,Floppy. The command uses trap statement to catch terminating exceptions. If the Set-SCVirtualMachine command fails, the string in the trap statement is displayed. Continue is used in the trap statement to continue running instead of exiting the foreach loop. The Out-Null cmdlet redirects the output to $Null instead of sending it to the console.

NOTE: The BootOrder parameter is used only for virtual machines on Hyper-V and Citrix XenServer hosts; it is not used for virtual machines on VMware ESX hosts. XenServer hosts do not support floppy disks, and therefore will ignore "Floppy" if listed in the boot order.

The last command sets the value for $ErrorActionPreference to the value stored in EAP.

For more information about the standard Windows PowerShell foreach loop statement, type: "Get-Help about_ForEach".


PS C:\> $EAP = $ErrorActionPreferencePS C:\> $ErrorActionPreference = "Stop"PS C:\> $VMs = @(Get-SCVirtualMachine)PS C:\> foreach($VM in $VMs){trap{"Fail: Cannot set BIOS for VM: $VM";continue} Set-SCVirtualMachine -VM $VM -BootOrder "PXEBoot","IDEHarddrive","CD","Floppy" | Out-Null}PS C:\> $ErrorActionPreference = $EAP

5: Specify an owner for all virtual machines without an owner.

This command gets all virtual machine objects on VMMServer01, selects only those virtual machine objects where no owner is listed, and specifies an owner for each virtual machine.


PS C:\> Get-SCVirtualMachine -VMMServer "VMMServer01.Contoso.com" | where {$_.Owner -eq ""} | Set-SCVirtualMachine -Owner "Contoso\ReneeLo"

6: Enable Dynamic Memory for an existing virtual machine.

The first command gets the virtual machine object VM06 and stores object in the $VM variable. To enable Dynamic Memory on a virtual machine, the virtual machine must reside on a host that is running Windows Server 2008 R2 SP1 or later.

The second command determines whether the virtual machine stored in $VM is in a powered off state. If the virtual machine is not in a powered off state, the command uses the Stop-SCVirtualMachine command to power off the virtual machine. For more information about powering off a virtual machine, type: "Get-Help Stop-SCVirtualMachine -detailed".

The last command enables Dynamic Memory, sets the startup memory to 1024 MB (this is the amount of memory on the host that will be allocated to VM06 upon startup) and the maximum memory to 2048 MB (this is the maximum amount of memory on the host that will be allocated to VM06).


PS C:\> $VM = Get-SCVirtualMachine -Name "VM06"PS C:\> if($VM.Status -ne "PowerOff"){Stop-SCVirtualMachine -VM $VM}PS C:\> Set-SCVirtualMachine -VM $VM -DynamicMemoryEnabled $True -MemoryMB 1024 -DynamicMemoryMaximumMB 2048
