That is true, but it's never been my decision.

Which Virtual platform to use, i.e. Microsoft or VMWare, supported or not, has always been the pervue of the Windows Administration team.

Even though they know it isn't fully supported by Microsoft management has always decided to take that risk. I neither condone or advise against it, since it's not my call.

I imagine that many other DBA's find themselves in a similar situation.
