Comment 9 for bug 1457404

Analysed the logs and updated the bug description.

I honestly don't think it should be treated as High for 6.1, as nova-network is marked as deprecated and multi_host=False is neither default , nor recommended setting for nova-network deployment.

The race condition, how unpleasant it is , can be worked around by putting a sleep between a SIGHUP and DHCPRELEASE sent to dnsmasq daemon. But we'll need to find a cleaner solution for 7.0, obviously.
