Inspired by this blog “A script to check the Integration Services Version on Hyper-V Host and Guests” and this blog “Hyper-V Integration Components version list table” the script below was created. The script mentioned in the first blog can only be executed on the host itself or via a PSSession on a remote host but is always one host at the time.
When using the script it is possible to use two different kinds of arrays. The first is a set of predefined hosts containing Hyper-V, the second is a OU in which al the HYper-V hosts are located. To use the first type of array you need to adjust the script arround line 29. When using the array based on the OU you don’t need to change the script.
The scripts has been tested on on Windows Server 2008 R2 and Windows 7. It uses WMI so please make sure your firewall is setup correctly.
# Specifies hosts to query.
# When using a small array.
# $hosts = @(‘<SERVERNAME 01>’, ‘<SERVERNAME 02>’)
# When using a specific OU.
import-module activedirectory
$hosts = Get-ADComputer –filter * -SearchBase “OU=<YOUR OU HERE>,DC=CONTOSO,DC=local”
# Tabel headers
Write-host ‘HostName’ ‘HosticVersion’ ‘GuestName’ ‘GuesticVersion’
# Defines import filter.
filter Import-CimXml
{
$cimXml = [XML]$_
$cimTree = New-Object -TypeName System.Object
foreach ($cimProperty in $cimXml.SelectNodes(“/INSTANCE/PROPERTY”))
{$cimTree | Add-Member -MemberType NoteProperty -Name $cimProperty.NAME -Value $cimProperty.VALUE}
$cimTree
}
# Retrieves all VMs except host itself.
foreach($hostName in $hosts)
{
# When using an small array please disable $hostName = $hostName.name
$hostName = $hostName.name
$hostSession = new-pssession -computername $hostname
$icVersionParent = invoke-command -session $hostSession -scriptblock {Get-ChildItem “HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization\GuestInstaller” | ForEach-Object {Get-ItemProperty $_.pspath} | select-object “Microsoft-Hyper-V-Guest-Installer-Win60-Package”}
$guests = Get-WmiObject -Namespace root\virtualization -ComputerName $hostName `
-Query “SELECT * FROM Msvm_ComputerSystem WHERE EnabledState=2 AND NOT Caption LIKE ‘Hosting Computer System’”
Remove-pssession -computername $hostname
# Processes all guests.
foreach($guestName in $guests)
{
Try {
$guestKVP = Get-WmiObject -Namespace root\virtualization -ComputerName $hostName `
-Query “ASSOCIATORS OF {$guestName} WHERE AssocClass=Msvm_SystemDevice ResultClass=Msvm_KvpExchangeComponent” –ErrorAction Stop
$icVersionGuest = $guestKVP.GuestIntrinsicExchangeItems | Import-CimXml | Where-Object{$_.Name -eq ‘IntegrationServicesVersion’}
$ichost = $icVersionParent.’Microsoft-Hyper-V-Guest-Installer-Win60-Package’
$icguest = $icVersionGuest.Data
If ($ichost -eq $icguest)
{Write-host $hostName,$ichost,$guestName.ElementName,$icguest -foregroundcolor green}
Else
{Write-host $hostName,$icVersionParent.’Microsoft-Hyper-V-Guest-Installer-Win60-Package’,$guestName.ElementName,$icVersionGuest.Data -foregroundcolor red}
}
Catch {
Write-host $hostName,$ichost ‘Host contains no running guests’ -foregroundcolor red
}
}
}
So with this script it is possible to define an array of servers by hand or define a specific OU where all the Hyper-V hosts are located in your Active Directory.
