It seems that it's failing also in other ovn based jobs, like e.g. https://8071573db65196ff81f4-57b370d78e2d22697b63acf3ce81f4b4.ssl.cf1.rackcdn.com/732081/3/check/ovsdbapp-neutron-ovn-tempest-ovs-release/3188ad1/testr_results.html
I will check that.

Looking at stable https://review.opendev.org/#/c/731477/ it runs with cirros 0.4.0 so it seems ovn-specific bug

Neutron has re-enabled this test because the bug has been fixed in OVN, see https://bugs.launchpad.net/neutron/+bug/1881558 for more information. Will close the neutron part of this bug.
