tempest-slow-py3 is failing while creating initial network in neutron

[Slawek Kaplonski]

Example of failure https://128d50eaaf9c22786068-bb0b8d002b29cd153f6a742d68988dd1.ssl.cf5.rackcdn.com/792299/6/check/tempest-slow-py3/fabc438/controller/logs/screen-q-svc.txt

tempest-full-py3 also failing with same error

- https://zuul.openstack.org/builds?job_name=tempest-full-py3

[Akihiro Motoki (amotoki)]

I found the same error in neutron-ovn-tempest-slow job (in the check queue) of https://review.opendev.org/c/openstack/neutron/+/776701.
https://zuul.opendev.org/t/openstack/build/5344d9bdec9346738499114c10a81aff/log/controller/logs/screen-q-svc.txt#1993

neutron-ovn-tempest-slow job runs tempest-slow job but it is non-voting, so the error was not detected when reviewing the patch.

I believe reverting https://review.opendev.org/c/openstack/neutron/+/776701 will fix the issue.

[Akihiro Motoki (amotoki)]

https://review.opendev.org/c/openstack/neutron/+/801478 reverts https://review.opendev.org/c/openstack/neutron/+/776701.

I also sent an update to openstack-discuss ML.

    Revert "[OVN][Placement] Add a SB Chassis event to track changes in BW config"

    This reverts commit df5cb28737453e2dfee17e177160fa6d7a59b7e0.

    The reverted commit triggers the failure of tempest-slow-py3 job.
    tempest-slow-py3 is equal to non-voting neutron-ovn-tempest-slow job
    in the neutron CI. It is a non-voting job so the error was not detected
    before merging it. To recover the tempest job in OpenStack wide,
    this commit reverts it.

    Promote neutron-ovn-tempest-slow job to be voting and gating

    This jobs is almost the same as tempest-slow-py3 since we switched
    OVN to be default backend in Neutron. And that tempest-slow-py3 job
    is used by many projects. So to avoid potential breaks of the gate for
    other projects (like we did recently, see related bug for details)
    let's make this job voting and gating.
    As it is really used in many different projects as voting and gating
    job already I don't think there is any issue with doing the same in
    the Neutron gate.
