SQL2005 and virtual machine environment

As always I got a notification of new KB articles from KBAlertz, one of those KBs was 956262 that talks about the issue that SQL2005 was NOT tested on VM environment (although it seems as this market is gaining more and more market share) and the support is limited in that way that if you have an issue that is not resolved using regular support than you have to reproduce the issue on a NON VM environment

I made a little search for some VMWare and SQL / Oracle articles and found some interesting:

• Ten Reasons Why Oracle Databases Run Best on VMware
• SQL Server Performance in a VMware Infrastructure 3 Environment (PDF)
• SQL Server on VMware Server(From the other Scott blog)

Now I ask you - isn't that weird, how can I even think of supporting this for other customers?
