This bug was initially created as a copy of Bug #1777523 Description of problem: This bug is clone of https://bugs.launchpad.net/tempest/+bug/1852807 upstream How reproducible: whenever you have the deployment with config_Drive= true with vfat as driver type or you use the testcase with instance deployed with ephemeral disk Steps to reproduce 1. deploy an instance with one already added vdb volume attached(Like I have used config drive format vfat that already took vdb volume) 2. run this testcase tempest.api.compute.volumes.test_attach_volume.AttachVolumeTestJSON.test_attach_detach_volume 3. This will fail in assertNotIn mismatch error like below as it tries to validate that vdb is detached or not which is set by libvirt assumption Actual results: Testcase failed Expected results: Testcase should have passed Additional info: Please look on this detailed upstream bug : https://bugs.launchpad.net/tempest/+bug/1852807
