You are asking Hyper-V parent's Hyper-V WMI provider to answer which one is VHD / passthrough disk.

Without asking parent, how to detect?

Without asking the parent you can't detect this information.

If anyone is trying to do this in VBScript then here's the code:

strComputer = ""

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\virtualization")

Set colSystems = objWMIService.ExecQuery("SELECT * FROM Msvm_VirtualSystemSettingData", _

"WQL", wbemFlagReturnImmediately + wbemFlagForwardOnly)

For Each objSystem In colSystems

WScript.Echo "ElementName: " & objSystem.ElementName

Set colResData = objWMIService.ExecQuery("Associators of {Msvm_VirtualSystemSettingData='" & objSystem.InstanceID & "'} Where ResultClass=Msvm_ResourceAllocationSettingData AssocClass=Msvm_VirtualSystemSettingDataComponent", _

"WQL", wbemFlagReturnImmediately + wbemFlagForwardOnly)

For Each objResData In colResData

If objResData.ResourceSubType = "Microsoft Virtual Hard Disk" Then

strConnection = Join(objResData.Connection, ",")

WScript.Echo " Connection: " & strConnection

End If

How Are My VHD’s/Passthough Disk’s Connected To My Virtual Machine?
