[Bug 1288923] [NEW] Failover of a network from one dhcp agent to another breaks DNS

 

Public bug reported:

Failing over a network from one dhcp agent to another results in a new
IP address for the dhcp port.  This breaks dns for all vms on that
network.    This can be reproduced by simply doing a "neutron dhcp-
agent-network-remove" and then a "neutron dhcp-agent-network-add" and
observing that the dhcp port ip address will change.
