Another reason to do it is as an added measure of privilege separation. 
If one virtual machine is compromised it probably won't lead to compromise
of the other VMs, barring security problems with the VM hypervisor.  In an
ideal world you wouldn't run, say, a web server and an NIS master on the
same machine, but running them in separate VMs provides almost the same
level of security without the extra box.
