You assume that the FAIR way to compare this is to compare a VM
to the same OS running on the raw hardware.
This is a bit OT, but years ago, using IBM's VM/370, I benchmarked
OS/VS1 running native vs. OS/VS1 running under VM/370 with several
online CMS users. The OS/VS1 running under VM/370 actually ran faster

than when native. The reasons for this were primarily due to a better
spooling algorithm for VM over OS, a larger physical page size, and a
few other details.
The bottom line is that VMWare provides some tremendous advantages as
long as you have the hardware to support it, and possibly tune it
correctly. And, as I mentioned in a previous post, Win4Lin also provides
a lower overhead as it was designed to run under Linux. In both cases,
on a personal machine, the end user may not notice any degradation.
