To clarify, the reason I am not using wait-for-state
(http://pastebin.ubuntu.com/11820672/) with WAIT_FOREVER=Y is primarily
because it will attempt to start the WAIT_FOR service once only then go
into an infinite wait loop which could be a problem in nova upgrade
scenarios where we would be
So it does appear that this a result of the openvswitch-switch service
taking a while to startup on boot/reboot. I have added some retry logic
to nova-compute and it appears that openvswitch is taking around 80s to
start:
neutron-ovs-cleanup start/pre-start, process 3055

So, this is possibly a result of neutron-ovs-cleaunp failing to start at
the time nova-compute does the wait-for-state (and implicitly tries to
start neutron-ovs-cleanup) due to the fact that openvswitch is not ready
to start at that very moment. I am going to attempt to resolve this by
