Hi all, The Cyborg compute node specification has been published: https://review.openstack.org/#/c/566798/ . Please review it. The main factors defined in this spec are: * The behavior with respect to accelerators when various Compute API [1] operations are applied. E.g. On a reboot/pause/suspend, the assigned accelerators are left intact. But, on a stop or shelve, they are detached. * The APIs for the newly proposed os-acc library. This is structured along the same lines as os-vif usage [2]. Changes are needed in Nova compute to invoke os-acc APIs on specific instance-related events. * Interactions of Cyborg with Glance in the compute node. The plan is to use Glance properties. No changes are needed in Glance.
