Public bug reported:

Recently we seem to have many the same devstack build failure in many
different gate jobs. The usual error message is:

+ lib/neutron_plugins/ovn_agent:start_ovn:714 :   wait_for_db_file /var/lib/ovn/ovnsb_db.db
+ lib/neutron_plugins/ovn_agent:wait_for_db_file:175 :   local count=0
