Ok, so we are on mitaka. Here we have VIPs that are a (Optional)
dependency for haproxy, which is a (Mandatory) dependency for
openstack-core from which all the others (nova, neutron, cinder and so
on) depends.
This means that if you are rebooting a controller in which a VIP is
active you will NOT have a restart of openstack-core since haproxy will
not be restarted, because of the OPTIONAL constraint.
So the behavior you're describing is quite strange.
Maybe other components are in the game here. Can you open a bugzilla
with the exact steps you're using to reproduce the problem and share the
sosreports of your systems?
Thanks,
