Hi all.
In Ussuri release we were completed the nova-cyborg-interaction feature, but there are some operations of instance were blocked [1], we will support evacuate/rebuild [2] and/or shelve/unshelve [2] instance with accelerator in Victoria release. In [2] we will add 'accel_uuids' parameter to the rebuild() method of virt driver and Ironic driver, in virt/driver [4] we are not implemented the rebuild() method, and the 'accel_uuids' will be ignored in virt/ironic/driver.
