Public bug reported:

Config:

Three MySQL nodes using percona (percona-cluster charm vai juju)
Two Neutron nodes providing network services to an openstack HA deployment (all done via juju).

Issue:

While testing failover of MySQL, we noticed that we could no longer
create instances of any sort.  Looking further it looks like neutron-
server can not talk to the mysql server that is currently active (using
the assigned VIP).

Attached is the server log from neutron-server.

Restarting neutron-server resolved the issue for us.
