Comment 25 for bug 1805645

There are two new problems.

1) The original fix was only applied to Rocky and above
2) The original fix only applied when a network node (neutron-gateway) was deployed. For distributed deployments (metadata running on nova-compute hosts) the problem still remains.

For 1, this is an update for nova-cloud-controller: https://review.opendev.org/701598

For 2, we need to pass the dns_domain information to nova-compute either directly from neutron-api or from nova-cloud-controller and update nova-compute templates similar to nova-cloud-controller.
