From what I can tell, nova never got a global-requirements sync update for this change on stable/kilo: https://review.openstack.org/#/c/200493/ We need that so we don't have to try and do it manually: https://review.openstack.org/#/c/200880/ Which is apparently busted in the gate-nova-requirements job: http://logs.openstack.org/80/200880/1/check/gate-nova-requirements/461f83f/console.html#_2015-07-12_12_28_17_768 -- Thanks, Matt Riedemann
