Public bug reported: Default subnet can exist only once in cloud and there are two tests that create default and one that updates to default, it happens that tests are running in parallel while the check for existing subnet is at the class level. So it happens that:
1) class checks for default subnet, it's not there 3) test1 creates default subnet -> it's fine, we now have our unique resource 4) test2 creates default subnet -> the error we see cause test1 has the default >From the tempest logs: Step1: 2017-08-10 07:03:12.341 3008 INFO tempest.lib.common.rest_client [req-07271c2f-6725-4f77-b676-a55a95adbf7b ] Request (DefaultSubnetPoolsTest:setUpClass): 200 GET http://10.0.0.103:9696/v2.0/subnetpools 0.418s ion/json', 'X-Auth-Token': '<omitted>'} Body: None Response - Headers: {'status': '200', u'content-length': '18', 'content-location': 'http://10.0.0.103:9696/v2.0/subnetpools', u'date': 'Thu, 10 Aug 2017 11:03:12 GMT', u'content-type': 'application/json', u'connection': 'close', u'x-openstack-request-id': 'req-07271c2f-6725-4f77-b676-a55a95adbf7b'} Body: {"subnetpools":[]} _log_request_full /usr/lib/python2.7/site-packages/tempest/lib/common/rest_client.py:425 Step2: 2017-08-10 07:03:12.998 3008 INFO tempest.lib.common.rest_client [req-6322524f-d1d8-4c7c-abd4-f08862bcec60 ] Request (DefaultSubnetPoolsTest:test_admin_create_default_subnetpool): 201 POST http://10.0.0.103:9696/v2.0/subnetpools 0.655s 2017-08-10 07:03:12.998 3008 DEBUG tempest.lib.common.rest_client [req-6322524f-d1d8-4c7c-abd4-f08862bcec60 ] Request - Headers: {'Content-Type': 'application/json', 'Accept': 'application/json', 'X-Auth-Token': '<omitted>'} Body: {"subnetpool": {"is_default": true, "prefixes": ["10.11.12.0/24"], "name": "tempest-smoke-subnetpool-2026337716", "min_prefixlen": "29"}} Response - Headers: {'status': '201', u'content-length': '508', 'content-location': 'http://10.0.0.103:9696/v2.0/subnetpools', u'date': 'Thu, 10 Aug 2017 11:03:12 GMT', u'content-type': 'application/json', u'connection': 'close', u'x-openstack-request-id': 'req-6322524f-d1d8-4c7c-abd4-f08862bcec60'} Body: {"subnetpool":{"is_default":true,"description":"","default_quota":null,"tenant_id":"542c5acbca3f49a0bc89d0903eb5c7e5","created_at":"2017-08-10T11:03:12Z","tags":[],"updated_at":"2017-08-10T11:03:12Z","prefixes":["10.11.12.0/24"],"min_prefixlen":"29","max_prefixlen":"32","address_scope_id":null,"revision_number":0,"ip_version":4,"shared":false,"default_prefixlen":"29","project_id":"542c5acbca3f49a0bc89d0903eb5c7e5","id":"dd1b15f4-0dc1-4582-9435-394a5b2bdea9","name":"tempest-smoke-subnetpool-2026337716"}} _log_request_full /usr/lib/python2.7/site-packages/tempest/lib/common/rest_client.py:425 Step3: 2017-08-10 07:03:15.667 3008 INFO tempest.lib.common.rest_client [req-24e48bfe-473f-44e0-aaf4-8f2debf81a0e ] Request (DefaultSubnetPoolsTest:test_convert_subnetpool_to_default_subnetpool): 400 PUT http://10.0.0.103:9696/v2.0/subnetpools/fb199e24-a9e2-443f-81cc-3c07c3bd7a20 0.842s 2017-08-10 07:03:15.668 3008 DEBUG tempest.lib.common.rest_client [req-24e48bfe-473f-44e0-aaf4-8f2debf81a0e ] Request - Headers: {'Content-Type': 'application/json', 'Accept': 'application/json', 'X-Auth-Token': '<omitted>'} Body: {"subnetpool": {"is_default": true}} Response - Headers: {'status': '400', u'content-length': '203', 'content-location': 'http://10.0.0.103:9696/v2.0/subnetpools/fb199e24-a9e2-443f-81cc-3c07c3bd7a20', u'date': 'Thu, 10 Aug 2017 11:03:15 GMT', u'content-type': 'application/json', u'connection': 'close', u'x-openstack-request-id': 'req-24e48bfe-473f-44e0-aaf4-8f2debf81a0e'} Body: {"NeutronError": {"message": "Invalid input for operation: A default subnetpool for this IP family has already been set.
