Title:
  Hypervisor crashes after instance is spawned

Status in OpenStack Neutron (virtual network service):
  Expired
Status in OpenStack Compute (Nova):
  Incomplete

Bug description:
  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.
