InstallVirtualGuestServices.ps1

Updated: January 22, 2009

Applies To: Virtual Machine Manager 2008, Virtual Machine Manager 2008 R2, Virtual Machine Manager 2008 R2 SP1

The following script checks all the virtual machines that are managed by the System Center Virtual Machine Manager (VMM) server to determine whether virtual guest services are installed. If they are not installed, the script installs Integration Components on virtual machines that reside on Hyper-V hosts and Virtual Machine Additions on virtual machines that reside on Virtual Server hosts. For an explanation of this script, see How to Install Virtual Guest Services Using a Script.
