Proposed Hypervisor Feature Requirements
The list below is not comprehensive, but is intended to provide a baseline set of features that hypervisors must implement. Not all of the items listed below may be required; more advanced features are listed to support discussion of where we draw the line.
| Feature | Required | Why | ||||
| Launch | Yes | We don't import running guests, which makes this critical | ||||
| Reboot | Yes | It's a pretty core operation that should be supportable everywhere (soft + hard?) | - | Shutdown/Start | Yes | Seems important too |
| Terminate | Yes | 'Cause | ||||
| Resize/Cold Migrate | Yes | When billed by the minute, ability to shrink/grow is important | ||||
| Rescue | Yes | Seems like important user-facing ability | ||||
| Pause/Unpause | No | Some hypervisors don't support this | ||||
| Suspend/Resume | No | Some hypervisors don't support this | ||||
| Inject networking | No | Doesn't make sense everywhere (?) | ||||
| Inject files | No | Trying to move away from this anyway | ||||
| Serial Console | No | Doesn't make sense everywhere | ||||
| VNC Console | No | Doesn't make sense everywhere | ||||
| SPICE Console | No | Limited to single-hypervisor support | ||||
| RDP Console | No | Limited to single-hypervisor support | ||||
| Attach/Detach Volume | Yes | Volumes are the default persistence mechanism | ||||
| Live Migration | No | Not all hypervisors will support this | ||||
| Snapshot | Yes | Basic function for bootstrapping environments | ||||
| iSCSI backing | No | |||||
| FibreChannel Backing | No | |||||
| Set admin password | No | Overlaps with rescue, not supported everywhere | ||||
| Boot from glance image | Yes | This is basic expected behavior | ||||
| Boot from volume | Yes | If volumes work, this should work too | ||||
| Works with nova-network | No | The (distant) future is neutron | ||||
| Works with neutron | Yes | Neutron is openstack's networking platform, so must be supported | ||||
| Supports configdrive | Yes | This is our preferred future file-based configuration mechanism | ||||
| Evacuate | No | |||||
| Volume Swap | No | Not supported everywhere |
