But the current EL6 repo looks already upgraded to Essex release. So I wonder if there is any way I can get back to the diablo rpms? You can get earlier packages from http://kojipkgs.fedoraproject.org/packages/ You could create your own repo from these and give it a higher priority. For your convenience I've created (but not tested) such a repo here: http://pbrady.fedorapeople.org/openstack-diablo-el6/ Details are in the README there. cheers, Pádraig.
