[Bug 1278531] [NEW] nested kvm on saucy kernel hangs

 

Public bug reported:

I have a precise host with saucy ubuntu kernel installed.  I installed
two VMs there, a saucy and a trusty guest.

In the saucy guest, non-accelerated qemu works fine, but accelerated kvm
hangs the first-level saucy guest completely, and pins it at 200% cpu
usage:

   qemu-system-x86 --enable-kvm -monitor stdio -vnc :1

On the trusty guest it works just fine.

** Affects: linux (Ubuntu)
