Description Daniel Alvarez Sanchez 2021-04-16 15:18:09 UTC 
neutron-ovs-cleanup script cleans the ports from the integration bridge and then Nova (os-vif) will plug the relevant instances ports to it.

This script doesn't run on ML2/OVN setups and it should for the same reasons it does on ML2/OVS.

afctully i dont think this is correct.

even ml2/ovs should not have this run regually
we dont expect this to be run upstream it ment as a tool to help fix leaked port when we hit bugs.

this is racy to run on start up as it can interfee with nova/libvirt plugin the interface if the resume gusts on boot config option is enabled

so i would suggest disabling this for both ml2/ovs and ml2/ovn by default.
