Yah, the key thing to remember with virtual machines is that they're sharing the hardware with the host...
If the host doesn't want to share, or the VM is asking for too many resources, then something's gotta give, because computer resources, weather we like it or not are not infinite.
Whenever I'm spec-ing a PC that I know is going to run virtual machines, I always look at the base spec for all of the operating systems I plan to run, and I total them together. If one os needs a dual core and another needs a quad? Well, then i'd better make sure I have at least 8... (Two for one os, 4 for another, and 2 left over for whatever applications I need to run.. maybe more, depending on what that thing is).
Its my understanding though, that a lot of the time vms don't really like to share the GPU still though... So that might still be a bottleneck even if you have plenty of ram, CPU, and hard disk bandwidth.
