Public bug reported:

I am running Grizzly on Ubuntu 13.04 (so the network service ==
Quantum).  Nova runs Quantum with LibvirtHybridOVSBridgeDriver and
LinuxOVSInterfaceDriver, while Quantum is configured to use GRE tunnels.
Further, Quantum runs on a dedicated node and VLAN.

Starting in mid-December, new Compute nodes that came online were unable
to spin new VMs.  At the moment the nova-compute.log indicated that the
instance had spawned successfully, the hypervisor system crashed with
the following console dump message (last screen's worth):
http://pastebin.com/004MYzvR.

The installation of the Compute packages are controlled by puppet:

The kernel being used is *not* controlled by Puppet and ends up being
whatever the latest and greatest version is in raring-updates.  The
kernels in use: 3.8.0.34.52.  I tried upgrading to 3.8.0.35.53 when it
became available, but that had no effect.

I'm lost.  No idea how to debug this.
