Comment 2 for bug 1938766

Looking at the log linked above and recent neutron-functional-with-uwsgi failures in neutron-lib changes, I think failures happened in create_default_drop_port_group() which is called in setUp().

"No such file or directory" happend in _collect_processes_logs which is triggered as part of the cleanup process [1]. self.mech_driver.nb_ovn.ovsdb_connection.stop hit Timeout exception but it is also part of the cleanup process [2].

create_default_drop_port_group() fails in all failures with "No such file or directory: '/tmp/tmps9cyr99c/ovn_northd.log'", so create_default_drop_port_group() looks the root failure and we need to fix it.
