Even for software-based virtualization (emulation is different), it 
wouldn't work so well, to the best of my knowledge.

It can be done, sure; it's not very stable.  I've spent time working with 
virtualization and doing something like trying to run XEN under VMware is 
possible and sometimes works, but not reliably enough for what I needed 
it for.
