Public bug reported:

Job like neutron-ovn-tempest-slow and neutron-ovn-tempest-full-
multinode-ovs-master are failing on spawning devstack with error like:

Oct 06 19:17:08 ubuntu-focal-ovh-gra1-0020322316 systemd[1]: devstack@dstat.service: Succeeded.

I don't see same errors on other jobs in neutron.
