The short answer is no.

The long answer is yes (using systems similar to those noted above) but it will be more work and maintenance than you want to take care of not to mention slow your sites down to the same speed as if they were on the same VM.

If it's efficiency you're looking for and you're running on IIS 6 (as much trouble as it's given, it's still a decent web-server), try creating multiple application pools. Works great for some of my more intensive stuff I do at work.

ALSO keep in mind that the more VMs you have running, the more ACTUAL CPU will be used. I've decided that VMs aren't the holy grail.
