Description Miguel Angel Ajo 2015-06-17 05:16:13 EDT

Description of problem:

When using tunnelling, if one of the hosts changed the hostname and tries to sync tunnels to neutron-server, this will throw an exception due to an unnecessary constraint, breaking the network.

Hostname changes are something neutron-server may survive to. Probably a log warning is enough, and the old hostname endpoint should be deleted.

Version-Release number of selected component (if applicable):

openstack-neutron-2015.1.0-8

How reproducible:

Always

Steps to Reproduce:
1. Install a single node AIO with tunnelling for tenant networks.
2. openstack-config --set /etc/neutron/neutron.conf DEFAULT host newhostname
3. service neutron-openvswitch-agent restart


Actual results:

 The exceptions keep happening for neutron-server in a loop as the agent tries to sync the tunnel, and fail.

Expected results:
 The hostname change doesn't break anything.
