Bug description:
Hi Neutrinos!
This is from Kolla-Ansible CI, it started happening in Victoria on May 28.
It affects all distros deb-ubu-centos and makes the jobs fail (ovs agent is
dead).
It does *not* affect OVN though.
br-ex exists before iteration:0 and acts fine in iteration:0 but not
in iteration:1.
The only quasi-relevant change in neutron seems to be
https://review.opendev.org/721554 but still it should only affect DVR
which we are not running. Odd.
Full logs with config and debug are attached.
The relevant logs look like this (bottom of the file):
