** Description changed: This issue appears to be a consequence of https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1420572 where we added a 'wait-for-state running' to the nova-compute upstart so as to ensure that neutron-ovs-cleanup has finished before nova-compute starts. I have started to spot, however, that on some hosts (metal only) there - is now a race between the two whereby nova-compute fails to start or - boot/reboot with the following in /var/log/upstart/nova-compute.log: + is now a race between the two whereby nova-compute sometimes fails to + start or boot/reboot with the following in /var/log/upstart/nova- + compute.log: ... libvirt-bin stop/waiting wait-for-state stop/waiting neutron-ovs-cleanup start/pre-start, process 3084 start: Job failed to start If I manually restart nova-compute all is fine. So this looks like a race between nova-compute's wait-for-state and neutron-ovs-cleanup's pre-start -> start/running.
