However I have some memory of us saying(in Austin?) that adding volume_type would be acceptable since it's a clear oversight in the list of parameters for specifying a block device. So while I greatly dislike Nova creating volumes and would rather users pass in pre-created volume ids I would support adding this parameter. I do not support continuing to add parameters if Cinder adds parameters though. > > > ____________________________________________________________________- > ________ > OpenStack Development Mailing List (not for usage questions) > Unsubscribe: OpenStack-dev- > requ...@lists.openstack.org?subject:unsubscribe > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
