Comment 35 for bug 1208455

I tried reproducing this while using trusty on the host and was unable to do so. I also could not reproduce with the trusty kernel (currently 3.12) running with saucy userspace on the host. So as far as I can tell the issue is fixed in 3.12.

I took a stab at trying to bisect, but something between 3.11 and 3.12-rc1 is causing the machine to not boot. With 3.12-rc1 my VMs failed to boot, and with 3.12-rc2 I couldn't reproduce the issue at all. So it looks like bisecting to find the fix will be nearly impossible. Going through the kvm commits in 3.12 revealed a lot of changes related to running nested VMs but nothing that stood out from the pack.

So if anyone _really_ needs this fixed in saucy, let me know, otherwise I'm going to assume that having it fixed in trusty is good enough.
