Public bug reported:

ii  nova-common                            1:2014.2.2-0ubuntu1~cloud0            all          OpenStack Compute - common files
ii  nova-compute                           1:2014.2.2-0ubuntu1~cloud0            all          OpenStack Compute - compute node base
ii  nova-compute-kvm                       1:2014.2.2-0ubuntu1~cloud0            all          OpenStack Compute - compute node (KVM)

I have a 14 compute node deployment, my VIP percona leader was axed and
one of the compute services did not reconnect.  13 did, so clearly there
is retry logic already involved that is working in most cases.

Will attach full stack trace, The missing log entry that all the good
units have seems to be this:

2015-05-12 19:55:52.867 229965 ERROR nova.servicegroup.drivers.db [-]
