VMware doesn't support VIA CPUs, and I think we would have compatibility 
issues with these instructions.  In general, most hypervisors would need 
to support decoding of the new instructions for complete emulation in 
various fault and corner cases.  In general, I would expect some trouble 
just running a hypervisor or VIA CPUs, as the test matrix is so low I 
can't point even to one working example.  Perhaps someone can correct me 
if they have got one up and running.
UML should work fine though.
