Comment 6 for bug 1660244

Just ran into this as confirmation.

Filed this bug which may or may not be a duplicate of this one. The root cause looks like the DB not being ready before corosync attempts to start nova-consoleauth.

If we decide single-nova-consoleauth=true is not valid with memcache we should enforce it early with a clear message in juju status.
