I just happened to be doing some stuff with kvmctl and I decided to run
todays git tree of kvmctl on my Thinkpad T61 (with 2.0 Core 2 Dou). I
get the following when trying to run "kvmctl test/x86/vmexit.flat":

root@laptop:/home/jerone/work/kvm-userspace/user# ./kvmctl
test/x86/vmexit.flat

exception 13 (0)

This result is better then the result of previous as of previous git
revisions of this week that would oops the kernel. It also does this
with smp.flat.
