Restarting the neutron-ovn-metadata-agent.service on the hypervisor cleared this issue so it looks like some sort of caching type problem in this service.

Note that the fact the port/instance was hardware offloaded is not material here - I just tripped on the same issue with virtio ports.

Also see a few of these:

Restarting the neutron-ovn-metadata-agent service resolves the issue.

The customer also faced this issue

Status changed to 'Confirmed' because the bug affects multiple users.

We also saw this after a round of package upgrades on a cloud. python3-neutron went from 2:16.2.0-0ubuntu2~cloud0 to 2:16.2.0-0ubuntu3~cloud0 and ovn packages went from 20.03.1-0ubuntu1.1~cloud0 to 20.03.1-0ubuntu1.2~cloud0 (i.e. not an upstream version change).

While looking to reproduce this issue we found this in the logs of both the neutron-ovn-metadata-agent and neutron-server:

I suspect the log excerpts printed in comments above is fallout from this condition and that both issues will go away with a fixed python-ovs.

Fix proposed upstream:
http://patchwork.ozlabs.org/<email address hidden>/

With the proposed fix in place local validation allows me to successfully create instances just after a full cloud reboot as well as after synthetic test of restarting all the OVN ovsdb-server processes at once multiple times.

It was actually already fixed upstream in [0] and backported to branch-2.13 in [1] which is tagged in v2.13.3.

0: https://mail.openvswitch.org/pipermail/ovs-dev/2020-September/375050.html
1: https://github.com/openvswitch/ovs/commit/cdf2cf98e31ea4c99f62bf7a2c57a22050a71bbd

So this would be fixed by a new point release update in Ubuntu.

2.13.3 uploaded for focal and groovy to:

  https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/3690

for testing.

The SRU for OVS 2.13.3 is tracked under bug 1920141

Packages have now built in:

  https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/3690

DPDK needed a fix for a regression introduced in the previous -update.

For visibility: I've filed a bug for adding monitoring of the Metadata agent via the HTTP layer: LP#1921653
