Which means some sensible behaviour
already exists if I don't call KVM_SET_CPUID2.
So what is it, #UD on CPUID?
I would have to check but I think you always get zeroes; not entirely
sensible.
In that case I would argue that you can't
break anything by changing that to something
sensible. :)
But anyway, since my problem is solved,
this is just a potential improvement for the
future, or the case for documenting.
