I recently took the Windows Server Virtualization preview (included with Windows Server 2008 release candidate 0) for a test drive. The intent was to get it installed, create some VMs, put them under load, and see what happens. As this is still pre-release it isn't fair to compare the performance in any absolute terms with either physcial servers. But I did think that it would be fine to put it under some stress and see how the new hypervisor handles the load.

The net results are posted on the wiki in the Microsoft Virtualization section. To sum it up shortly - the system handled the stress very well.

As new releases of the virtualization technolgy to be included with W2K8 come out, we will evaluate them and post what results we can. Let me know what types of things you would like to see.
