[Bug 1379340] Re: qemu-kvm guest panic for AMD smp trusty guests

[Chris J Arges]

I'm able to reproduce this and currently it looks like its fixed in
3.18-rc1. The main things that need to be enabled are 'cpu mode=host-
passthrough' and > 1 CPU. If 'cpu mode=host-model' is enabled and > 1
CPU things work fine.

The differences in cpu features were:
npt nrip_save tsc_adjust

I've also tried this on Intel platforms and was unable to reproduce, I
was able to reproduce this on an AMD Opteron 6276 processor.

Working on finding the patch to backport.
