openstack-nova: [RFE] The launched instance doesn't migrate to live node(s) upon reboot, nor does it boot after the rebooted node resumes normal operation.
Steps to reproduce:
1. Launch an instance on overcloud with 2 computes and working live migration.
2. Reboot the compute node on which the instance is running.
3. Check the status of the instance on both computes.
Result:
The instance isn't launched on the remaining compute.
After the rebooted compute resumes, the instance still won't launch.
Expected result:
The instance should either launch on another compute or resume on the rebooted one.

This is actually expected behaviour, the only thing that would be expected to work in this case would be evacuate. If you want to live migrate you need to initiate it while the host is still up.
