Public bug reported: Using Zed and Ubuntu and OVN as the ml2 driver.
Neutron Server Version 21.0.0 OVN Version 22.09.0 When adding/removing floating IPs the neutron server errors with the following 2023-02-23 03:30:05.842 25044 INFO neutron.plugins.ml2.drivers.ovn.mech_driver.mech_driver [None req- accc7595-320b-47e4-93e4-b07f6b205295 - - - - - -] Refusing to bind port 5266e0cd-1064-4baa-9679-8c5f2eb13d29 on host sora due to the OVN chassis bridge mapping physical networks [] not supporting physical network: provider 2023-02-23 03:30:05.843 25044 ERROR neutron.plugins.ml2.managers [None req-accc7595-320b-47e4-93e4-b07f6b205295 - - - - - -] Failed to bind port 5266e0cd-1064-4baa-9679-8c5f2eb13d29 on host sora for vnic_type normal using segments [{'id': '5621a693-771d-4a57-beb4-d7a6e8dfc1b9', 'network_type': 'flat', 'physical_network': 'provider', 'segmentation_id': None, 'network_id': '71cbb38e-dc91-4db4-9a3a-7e499cd3fd69'}] The floating IPs work as expected though so I am unsure why this error is given.
