Sure, I host PostgreSQL on vmware-server. As far as PostgreSQL or any
application is concerned - it makes no difference at all - which is the
point of virtualization. I'd recommend vmware-server because it is (a)
free and (b) much more mature compared to the other two. The price of
virtualization is slower I/O so for high loads you need (1) more RAM
[never a bad thing anyway] and (2) emphasis on a good I/O subsystem
[also never a bad thing].
