So VMWare messes around with clock timing.
This is a Bad Thing if you're trying to do things that rely on
faithful timing, such as audio mixing for a MeetMe conference room.

If you're only doing very simple things like playing messages or
ordinary bridged two-way phone calls it probably wouldn't be as bad.

If call quality matters, at all, I wouldn't go that route. If managing
a real server with asterisk is too hard for your data center, may I
humbly suggest an asterisk appliance?
