Comment 7 for bug 1839300

The hostname configured for services must indeed be exactly the same between the principle charm, in this case nova-compute, and the neutron-openvswitch subordinate for interactions with other parts of the deployment to work.

It is unfortunate that the change appears to have slipped on locking that down for all use cases.

While we start work to fix that I would like to hear more about the different regression you refer to in #6.
