Cyborg Support Matrix

Cyborg supports specific operations on VMs with attached accelerator resources, which are generally a subset of the full set of VM operations supported by Nova (nova-vm-ops).

In this release, these operations have a dependency on specific Nova patches (nova-patches). They can be expected to work in Cyborg only if and when these Nova patches get merged without significant changes. These operations are not supported in this release since the dependencies are not met.

VM Operations Expected to Work With Nova Dependencies

VM Operation	Command
VM creation	openstack server create
VM deletion	openstack server delete
Reboot within VM	ssh to VM and reboot in OS
Soft reboot	openstack server reboot --soft
Pause/Unpause	openstack server pause, openstack server unpause
Lock/Unlock	openstack server lock, openstack server unlock
Rebuild/Evacuate	openstack server rebuild
Shelve/Unshelve	openstack server shelve, openstack server unshelve

Operations not listed here may or may not work.
