Description of problem: The tempest test neutron_tempest_plugin.api.admin.test_quotas.QuotasTest.test_detail_quotas is failing for OVN with: Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/tempest/common/utils/__init__.py", line 107, in wrapper return func(*func_args, **func_kwargs) File "/usr/lib/python2.7/site-packages/neutron_tempest_plugin/api/admin/test_quotas.py", line 145, in test_detail_quotas quota_set[key]['used']) File "/usr/lib/python2.7/site-packages/testtools/testcase.py", line 350, in assertEqual self.assertThat(observed, matcher, message) File "/usr/lib/python2.7/site-packages/testtools/testcase.py", line 435, in assertThat raise mismatch_error testtools.matchers._impl.MismatchError: 1 != 2 The reason of the failure has to deal with the networking-ovn's metadata implementation. Basically, when metadata is enabled (and it's for the CI) and we create a network resource for OVN, networking-ovn will also allocate a port to be used by the metadata agent [0]. That port will deduct 1 from the user's quota for ports and that is causing the difference there which is making the test fail. ... Since this is an API test (that runs when the quota_details API extension for neutron is enabled) I think that there's little to us to do to fix it without having to do a big refactor in the networking-ovn's code, which I don't think is worth of it to fix this test. Perhaps, disabling that extension in the CI for now would be the easiest way to deal with the problem.

The patch [0] uses a different approach and calculates the number of used ports on that test after the network has been created. Perhaps that's more generic and doesn't require disabling the test or the extension for OVN. [0] https://review.openstack.org/#/c/564757/

Enter draft text in the "Doc Text" field. Thanks Joanne, This bug is only related to a test run so I don't think it needs any documentation about it. I've set the requires_doc_text flag to "-" as requested for this case.
