A. Most Microsoft products are supported under Virtual Server 2005 now, which means you get the same support for the application or service running in a virtual environment as you would if it was running on a physical machine.

Support for Microsoft products running under a VMware host is typically on a "best-effort" basis, depending on your contract with Microsoft. Microsoft will typically attempt to help resolve the problem, but you might reach a point where you're told to reproduce the problem outside of VMware to get continued support.
