[Bug 1208455] Re: general protection fault running apt-get inside double nested kvm VM

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.
