Yes, that would really be interesting, and I think the answer would also
depend on the applications tested.

IO based apps would probably be fairly slow on VMWare compared to the others,
I think.  Since VMWare goes through the trouble of actual hardware emulation.

I haven't looked at vm behavior differences between these, though I am
familiar with VMWare's behavior.
