Enabling processor compatibility with a script [Hyper-V]
When we released Windows Server 2008 R2 we added the ability to make a virtual machines processor more compatible for migration between different hardware platforms (details here ). Here is a PowerShell script to do this for you: # Function for handling WMI jobs / return values Function ProcessResult($result, $successString, $failureString) { #Return success if the return value is “0″ if ($result.ReturnValue -eq 0) {write-host $successString} #If the return value is not “0″ or “4096″ then the operation failed ElseIf ($result.ReturnValue -ne 4096) {write-host $failureString ” Error value:” $result.ReturnValue} Else { #Get the job object $job=[WMI]$result.job #Provide updates if the jobstate is “3″ (starting) or “4″ (running) while ($job.JobState -eq 3 -or $job.JobState -eq 4) {write-host $job.PercentComplete “% complete” start-sleep 1 #Refresh the job object $job=[WMI]$result.job} #A jobstate of “7″ means success if ($job.JobState -eq 7) {write-host $successString} Else {write-host $failureString write-host “ErrorCode:” $job.ErrorCode write-host “ErrorDescription” $job.ErrorDescription} } } # Prompt for the Hyper-V Server to use $HyperVServer = Read-Host “Specify the Hyper-V Server to use (enter ‘.’ for the local computer)” # Prompt for the virtual machine to use $VMName = Read-Host “Specify the name of the virtual machine” # Get the management service $VMMS = gwmi -namespace rootvirtualization Msvm_VirtualSystemManagementService -computername $HyperVServer # Get the virtual machine object $VM = gwmi MSVM_ComputerSystem – filter “ElementName=’$VMName’” -namespace “rootvirtualization” -computername $HyperVServer # SettingType = 3 ensures that we do not get snapshots $SystemSettingData = $VM.getRelated( “Msvm_VirtualSystemSettingData” ) | where {$_.SettingType -eq 3} # Get the processor setting data $ProcSetting = $SystemSettingData.getRelated( “Msvm_ProcessorSettingData” ) | select -first 1 # Enable processor compatibility $ProcSetting.LimitProcessorFeatures = $true # Apply the changes to the processor setting data back to the virtual machine $result = $VMMS.ModifyVirtualSystemResources($VM, $ProcSetting.GetText(1)) # Process the result ProcessResult $result “Enabled limited processor features.” “Failed to enable limited processor features.” Cheers, Ben
