--- Comment #5 from Mark Asselstine <asselsm@xxxxxxxxx> ---
You are not being clear if this is falling over in the guest or native, which
is it?

Can you use gdb to confirm the instruction which is failing?

I am no expert but I have built the latest mainline kernel as of today and I
believe the failure is in the call to 'rdpmc'. The PCE bit (9th bit) in CR4
appears to be 0 and thus RDPMC can only be used in ring 0. If it is a guest
which is failing this might explain the oops.
