Deployed focal-ussuri from charm-neutron-api-plugin-ovn gate tests and
applied pending Neutron patch [0].
With two instances running we can see the following information in the OVN DB:
$ sudo ovn-nbctl list dns
_uuid : d51565b8-4ddb-4038-8a92-55e25247a419
external_ids : {ls_name=neutron-de1d0eb4-405a-4fc1-98ef-b93c7a2a4524}
records :
{"114.0.168.192.in-addr.arpa"=zaza-neutrontests-ins-1.openstack.example,
"13.0.168.192.in-addr.arpa"=zaza-neutrontests-ins-2.openstack.example,
zaza-neutrontests-ins-1="192.168.0.114",
zaza-neutrontests-ins-1.openstack.example="192.168.0.114",
zaza-neutrontests-ins-2="192.168.0.13",
zaza-neutrontests-ins-2.openstack.example="192.168.0.13"}
Control test:
From instance forward DNS lookups of other instance names work:
$ host zaza-neutrontests-ins-1.openstack.example
zaza-neutrontests-ins-1.openstack.example has address 192.168.0.114
But reverse DNS lookup of other instance IP does not work:
$ host 192.168.0.114
Host 114.0.168.192.in-addr.arpa. not found: 3(NXDOMAIN)
Upgrade to packages from -proposed:
$ juju run --application ovn-chassis 'dpkg -l | grep ovn'
- Stdout: |
ii neutron-ovn-metadata-agent 2:16.4.2-0ubuntu1
all Neutron is a virtual network service for

Confirm updated packages work:
$ sudo systemctl restart systemd-resolved
