Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1270943 Title: Hypervisor crashes after instance is spawned Status in OpenStack Neutron (virtual network service): Expired Status in OpenStack Compute (Nova): Won't Fix 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: 1:2013.1-0ubuntu2 nova-common 1:2013.1-0ubuntu2 nova-compute 1:2013.1-0ubuntu2 nova-compute-kvm 1.9.0-0ubuntu1 openvswitch-common 1.9.0-0ubuntu1 openvswitch-datapath-dkms 1.9.0-0ubuntu1 openvswitch-datapath-source 1.9.0-0ubuntu1 openvswitch-switch 1:1.0.3-0ubuntu1 python-cinderclient 1:2013.1.4-0ubuntu1 python-glance 1:0.9.0-0ubuntu1.2 python-glanceclient 1:2013.1.4-0ubuntu1.1 python-keystone 1:0.2.3-0ubuntu2.2 python-keystoneclient 1:2013.1-0ubuntu2 python-nova 1:2.13.0-0ubuntu1 python-novaclient 1:1.1.0-0ubuntu1 python-oslo.config 1:2013.1-0ubuntu2 python-quantum 1:2.2.0-0ubuntu1 python-quantumclient 1:1.3.0-0ubuntu1 python-swiftclient 1:2013.1-0ubuntu2 quantum-common 1:2013.1-0ubuntu2 quantum-plugin-openvswitch 1:2013.1-0ubuntu2 quantum-plugin-openvswitch-agent 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.
