Registered by Guangya Liu (Jay Lau) on 2014-01-28

This blueprint has been superseded. See the newer blueprint "Enable cold migration with target host - Queens" for updated plans.

Now cold migration do not support migrate a VM instance with target host, we should enable this feature in nova.

Whiteboard

If we are considering this, we need to probably make this consistent between boot, live migrate, resize, rebuild. It does not necessarily need to be part of this blueprint. We just need a story that works for the above. - Christopher Lefelhocz

@Chris, for boot, we are using "--availability-zone zone:host:node" for target host deployment.

For other commands: live migration: already supported
resize: not support target resize
rebuild: not support target host rebuild
evaucate: Support target host evacuate

Yes, I think that we can make those commands support target host operations in future bps. --jay-lau-513
