Microsoft not supported apps in a VM environment

I have just seen this page on the MCS Ireland site.

It points to a KB article 897614 which details the apps which MS doesn't support on a VM environment.

Take a look at the site but basically it reads as follows:

MS Speech Server

ISA 2000 and 2004

Sharepoint Portal Server

MIIS 2003

MIIFP

NLB

 

None of the above are supported in a VM environment.
