Description of problem: When having ceph or another non-standard volume backend, tempest needs to be configured differently. Cinder admin tests have backend related options and unless the tempest-config tool is provided with some hints it won't be able to figure on its own. Upstream, devstack gets provided with the following options: https://github.com/openstack-dev/devstack/blob/master/lib/tempest#L69-L74 So for this case we'd need OSP-Director to specifically provide tempest with the following option: TEMPEST_STORAGE_PROTOCOL=ceph In order for it to run properly, as it can't discover this on its own.
