How to get data (like the integration services version) from Msvm_KvpExchangeDataItem in Hyper-V

Today, if you are using VMM, you can quickly and easily find out if your VM has the integration components installed by using this simple PowerShell script.

PS D:\Windows\system32> get-vm | select name, hostname, hasvmadditions, vmaddition | format-list

Name : vmonmlmich
HostName : car-1.contoso.com
HasVMAdditions : False
VMAddition : Not Detected

Name : win2k8r2
HostName : AMUNRA.contoso.com
HasVMAdditions : True
VMAddition : Detected
>>

The problem is that VMM does not give you the version information for the Integration Components in Hyper-V. if you would like to get that data, you need to use the Msvm_KvpExchangeDataItem property. Below is a script and its output that gives you all that data for all Running VMs with Integration Components installed in Hyper-V.

Option Explicit

Dim WMIService
Dim KvpComponents
Dim VMList
Dim VM
Dim item
Dim component
Dim xml
Dim nodeValue
Dim nodeName

'Create the XML component
Set xml = createObject("MSXML2.DOMDOCUMENT.3.0")

'Get instance of 'virtualization' WMI service on the local computer
Set WMIService = GetObject("winmgmts:\\.\root\virtualization")

'Get all the MSVM_ComputerSystem object
Set VMList = WMIService.ExecQuery("SELECT * FROM Msvm_ComputerSystem")
For Each VM In VMList
if VM.Caption = "Virtual Machine" then
WScript.Echo "========================================"
WScript.Echo "VM Name: " & VM.ElementName
WScript.Echo "VM GUID: " & VM.Name
WScript.Echo "VM State: " & VM.EnabledState

if VM.EnabledState <> 2 then
  Wscript.Echo "VM is not in a running state, so no KVPs can be exchanged"
end if

' Get the list of KvpComponents
Set KvpComponents = WMIService.ExecQuery("SELECT * FROM Msvm_KvpExchangeComponent") '.ItemIndex(0)

For Each component in KvpComponents

' ensure that we are displaying the correct settings for the VM based on its instance ID/Name
If UCase(component.SystemName) = UCase(VM.Name) then

   Dim GuestItems
    GuestItems = component.GuestIntrinsicExchangeItems

   ' Now enumerate the Msvm_KvpExchangeDataItem's that are in XML format
   For Each item In GuestItems

  xml.async = false
  xml.resolveExternals = false
  xml.validateOnParse = false
  xml.loadXML item

   If xml.parseError.errorCode Then
         Wscript.Echo "--> Xml Document Parse Error: " & vbcrlf & _
                     " Reason = " & xml.parseError.reason & vbcrlf & _
                     " Line = "    & xml.parseError.line & vbcrlf & _
                     " linePos = " & xml.parseError.linePos & vbcrlf & _
                    " srcText = " & xml.parseError.srcText & vbcrlf & _
                    " ErrorCode = " & xml.parseError.ErrorCode & vbcrlf
         'WScript.quit
   Else
   xml.setProperty "SelectionLanguage", "XPath"
   set nodeName = xml.selectSingleNode("//INSTANCE/PROPERTY[@NAME='Name']")
   set nodeValue = xml.selectSingleNode("//INSTANCE/PROPERTY[@NAME='Data']")
   Wscript.Echo nodeName.Text & " --> " & nodeValue.Text
  End If

Next
End If
Next

end if
Next

Here is some example output as well. The Integration components version is the IntegrationServicesVersion property:
