Dear OpenStack developers, as you suggested, we have written individual specs for Nova [1] and Cinder [2] so far and will write another spec for Glance soon. We'd appreciate any feedback and reviews on the specs :) Thank you in advance, Markus Hentsch [1] https://review.openstack.org/#/c/608696/ [2] https://review.openstack.org/#/c/608663/
