i never tried it for real, but i'm in the progress of setting up a PBX 
system and decided to go with a dedicated box since i need more pci 
slots then my regular virtualised box could provide.

However, i have heard that many have succesfully used asterisk on a 
VServer, which i usually use when installing new services.

have some old notes in the link below and the testing setup worked fine. 
VServer is more an advanced chroot so i don't think you will have the 
problems some mentioned when going for the heavier virtualisation types 
like Xen.
just make sure the card is reachable inside the guest
