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.
