The new white paper "Managing Virtual Server Host Clustering using System Center Virtual Machine Manager 2007" is available in the download center at: http://download.microsoft.com/download/3/2/8/32849b7a-4f69-4c20-a988-333d954b3500/VMMandVSHostClustering_final.doc.

"This document provides an introduction to the methods and concepts that Information Technology (IT) professionals can use to manage Virtual Server clustered hosts using VMM. Virtual Server host clustering allows you to use a small number of physical servers to provide a wide variety of services, while maintaining the availability of the services that you provide. If a physical host server requires scheduled or unscheduled downtime, another host server is able to quickly begin supporting services. "

The paper also includes an updated Havm.vbs script you cna use to ensure that in a Virtual Server host cluster managed by Virtual Machine Manager, the virtual machines function correctly when a command is issued from the VMM Administrator Console or from the Cluster Administrator snap-in. The script is configured as a Generic Script resource in the cluster.

NOTE: use the updated script from Appendix A in this document instead of the Havm.vbs script included in the Virtual Server Host Clustering Step-by-Step Guide for Virtual Server 2005 R2. The updated script in Appendix A already contains the correct variables for usage with VMM.
