Well, like I said, if I don't add an entry for it in struct kvm_cpuid2
that's passed to KVM_SET_CPUID2 ioctl, I see a triple fault on Core 2
Duo CPU that doesn't seem to have native 0x80000008.
Do you have a function 8, though? Looks like a bug in kvm may confuse
the two.
Yeah, the host has function 8. I'm more than happy to test patches to
fix the problem.
