So tonight I was playing around with deployment at home. Having tried both System Center Essentials and System Center Configuration Manager, it was time for another deployment solution. Since my company has a sister company specializing in system management software, I decided to give them a try. After installing I needed to find the netboot GUID since I didn’t really like using the mac address. So how do I get the netboot GUID of my Hyper-V virtual machines? Well powershell of course.

The powershell snippet:

$VMs = Get-CimInstance -Namespace root\virtualization\v2 -Class Msvm_ComputerSystem|
  Where-Object {$_.Caption -eq 'Virtual Machine'}
ForEach ($vm in $VMs)
 {
   $biosguid=Get-CimInstance -Namespace root\virtualization\v2 -class Msvm_VirtualSystemSettingData |
     Where-Object {$_.VirtualSystemIdentifier -eq $vm.Name}|
     Select-Object -ExpandProperty BIOSGUID
   $vm | Select @{label='Name';expression={$vm.ElementName}},
     @{label='netbootGUID';expression={$biosguid}}
 }

So now I can continue testing Specops Deploy / OS. Also I wrote a function that does this, see my blog about Powershell function for getting the netboot GUID.
