PDC Teaser – Attaching a VHD to A Virtual Machine

  • Article

PDC is just around the corner now – I am giving the dry run of my talk tomorrow morning, so of course I am working on my demo’s today…  Just to give you a bit of a teaser here’s one of the scripts that I am using in one of my demo’s…

This script will take a VHD and attach it to the second port of the first IDE controller, just change the address numbers and you can change where it get’s attached.

Note that I am using the ProcessWMIJob function from Hyper-V WMI: Rich Error Messages for Non-Zero ReturnValue (no more 32773, 32768, 32700…)

$vhdToMount = "c:\test.vhd" $HyperVGuest = "ScriptTest" $VMManagementService = Get-WmiObject -class "Msvm_VirtualSystemManagementService" -namespace "root\virtualization" $Vm = Get-WmiObject -Namespace "root\virtualization" -Query "Select * From Msvm_ComputerSystem Where ElementName='$HyperVGuest'" $VMSettingData = Get-WmiObject -Namespace "root\virtualization" -Query "Associators of {$Vm} Where ResultClass=Msvm_VirtualSystemSettingData AssocClass=Msvm_SettingsDefineState" $VmScsiController = (Get-WmiObject -Namespace "root\virtualization" -Query "Associators of {$VMSettingData} Where ResultClass=Msvm_ResourceAllocationSettingData AssocClass=Msvm_VirtualSystemSettingDataComponent" | `                         where-object {$_.ResourceSubType -eq "Microsoft Emulated IDE Controller" -and $_.Address -eq 0}) $DiskAllocationSetting = Get-WmiObject -Namespace "root\virtualization" -Query "SELECT * FROM Msvm_AllocationCapabilities WHERE ResourceSubType = 'Microsoft Synthetic Disk Drive'" $DefaultDiskDrive = (Get-WmiObject -Namespace "root\virtualization" -Query "Associators of {$DiskAllocationSetting} Where ResultClass=Msvm_ResourceAllocationSettingData AssocClass=Msvm_SettingsDefineCapabilities" | `                         where-object {$_.InstanceID -like "*Default"}) $DefaultDiskDrive.Parent = $VmScsiController.__Path $DefaultDiskDrive.Address = 1 $NewDiskDrive = ($VMManagementService.AddVirtualSystemResources($Vm.__Path, $DefaultDiskDrive.PSBase.GetText(1)) | ProcessWMIJob $VMManagementService "AddVirtualSystemResources").NewResources $DiskAllocationSetting = Get-WmiObject -Namespace "root\virtualization" -Query "SELECT * FROM Msvm_AllocationCapabilities WHERE ResourceSubType = 'Microsoft Virtual Hard Disk'" $DefaultHardDisk = (Get-WmiObject -Namespace "root\virtualization" -Query "Associators of {$DiskAllocationSetting} Where ResultClass=Msvm_ResourceAllocationSettingData AssocClass=Msvm_SettingsDefineCapabilities" | `                         where-object {$_.InstanceID -like "*Default"}) $DefaultHardDisk.Parent = $NewDiskDrive $DefaultHardDisk.Connection = $vhdToMount $VMManagementService.AddVirtualSystemResources($Vm.__Path, $DefaultHardDisk.PSBase.GetText(1)) | ProcessWMIJob $VMManagementService "AddVirtualSystemResources"
