Comment 9 for bug 1940844

After comments in https://review.opendev.org/c/openstack/tripleo-heat-templates/+/805980 I checked logs from failed and passed jobs once again. I think that the difference is in ovn package: when it passed it was ovn2.13.x86_64 20.12.0-135.el8 and when it failed it was ovn2.13-20.12.0-161.el8.x86_64 - most likely ovn2.13-20.12.0-161.el8.x86_64 can't work properly with openvswitch2.12 which was installed on the node initially (and as never restarted, used for all the time).

IMO the best solution to fix that issue will be to install supported ovs version (openvswitch2.13) since the beginning of the job so it will be used even without restart.
