Are you talking about putting two DC instances on ONE host or two DC instances 
where each instance has its own host?
Which VMware product are they thinking on using?
What is the reason for such a scenario?
 
DCs should only be administered by domain admins (or in other words: highly 
trusted and knowledgable people). Putting a DC in a virtual session on a host 
means that the host should also be treated as if it were a DC and thus that 
same host should only be administered by highly trusted and knowledgable people
 
And as someone else also pointed out.... make sure you use ONLY ONLY ONLY ONLY 
supported backup mechanisms that are AD aware. DO NOT USE images, snapshots or 
whatever to backup DCs.
Be carefull for USN rollbacks:

PS.:
Another one I heard a few days ago was that someone wanted to use the mirror of 
the DC1 as a backup. The procedure looked like this:
* shutdown DC
* remove one of the mirror disks
* start the DC
* make the update
* if something goes wrong shutdown the DC, remove the other mirror disk and 
re-insert the previously removed mirror disk and rebuild the other
 
DON'T DO THAT!!! (it is like an image and it will hurt you)

Subject: [ActiveDir] Putting a DC on VMware



Hi all 

One of our sites is looking to put two DCs on VM ware.  I'm not too sure this 
is really the best thing to do.  Am I being too paranoid?  Can anyone point me 
in the right direction regarding suggestions on running a DC on Vmware?  Even 
if there are white papers for running Exchange 2000 on Vmware?

Thanks all 

Russ
