Since there are many problems when applying cinder v2 api, like cannot attach volumes to VM from nova, and there may be other problems in glance, the integration of cinder v2 api and other services is not well tested and the related configurations are not clear yet. We'd better revert the cinder api version back to v1 before all things are clear. Closes-bug: #1388741 Change-Id: Ic27a437be3c45e8a522c9c50b1e658de4ee79e94
