Lucas Meneghel Rodrigues also reproduced this, it seems to be processor
dependent.  I haven't debugged it yet because it doesn't reproduce on
the two systems I've tested on (Ivy Bridge i7 and Haswell Xeon E5).

Can you please also try loading the kvm-intel module with the
"unrestricted_guest=0" parameter, and see if it also reproduce?

It might be a processor bug too.
