Running kvmctl causing seg fault on intel vt system
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

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.
