Comment 2 for bug 1911788

Thank you for the bug. To diagnose communication issues between the Octavia units and the cloud we must start by looking at the state of tunnels and port bindings.

Take a look at the Neutron ports created by the Octavia charm, for example `octavia-health-manager-octavia-0-listen-port`:
- Does the `binding_host_id` match the FQDN of the Octavia container?
- Does the `binding_vif_type` field say 'ovs' or does it say 'binding_failed'?

Since you are using OVN you will also have rich logging in /var/log/ovn/ovn-controller.log which would show evidence of any shortname vs. FQDN issues.

There is an ongoing issue with deploying OVS/OVN in LXD containers on MAAS as detailed in bug 1896630. The root of the issue is somewhere below the charms but the linked bug contain steps to work around the issue.
