Bug 1812009

bridge not found for localnet port 'provnet-2804478a-b3af-4885-8470-5abc6ea5294a' with network name 'datacentre'

this sounds like somebody removed the provider bridge. The logs lack ovs-vswitchd.log and openvswitch commands to confirm provider bridge was present and bridge mappings configured correctly. Can you please provide such logs?

First we don't use DVR so I don't think mapping of br-ex in the compute is relevant here.
Second, Are you sure it's a duplicate of the other bug? We are not consuming FDP as far as I can tell

Yes, that was a red herring.

To the best of my knowledge, OVN is not cross-tagged for OSP16 but shipped via FDP channels. If you don't consume FDP, you can try to update ovn-controller to the version from comment 11 to see if it fixes the crashes for you. OVN version containing the fix was shipped with FDP 20.B.

The duplicated bug is not correct as it's just a BZ to track the move into OSP13. This BZ is against OSP16.
@Numan, @Kuba do we have the BZ against ovn2.11 that fixes the crash so that we can mark it as dup of this? Otherwise let's repoen this one and mark it as TestOnly.

I don't have the original BZ against OVN. Re-opening this one as suggested.
