I think we should use the CPUID instruction (leaf 0x40000000) to
detect
the hypervosor as we are doing in Xen.

Is that leaf reserved for such use by Intel?


What I can say is that we (including the H/W teams) reviewed it
internally.

I've switched to using CPUID. I noticed that Xen also uses 0x400000001 so I'm presuming that that is okay too?
