This works. I've done it on occasion for testing. However, because virtual 
PCs rarely operate on a real-time clock, mostly emulating these features, 
you will find that anything that read/writes to disk will suck badly. For 
example, it is nearly impossible to use the Voicemail features of Asterisk 
under Vmware, CoLinux or UserMode Linux. Believe me, I've tried! ;)

This is one of the main reasons that AstWind has stagnated. The timing 
granularity of the virtual machines is not acceptable for doing anything 
IO related.
