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.
