Update: it seems there is a bug in kolla-ansible causing this - we are
setting OVS system-id based on {{ inventory_hostname_short }} and if
Ansible inventory contains ip addresses - it will cause multiple OVN
chassis to have the same system-id - and they will ,,override'' each
other - which means OVN will get multiple create/delete events per
second - which results in 100% CPU usage of Neutron and OVSDB.
