Provided that it's VMWare ESX, and you have hardware virtualization
technologies enabled, and you install vmware-tools on your guest, then there
is no measurable performance degradation either in terms of CPU or disk.

The same is probably true for other hypervisors, but ESX is the one I can
speak on.
