The Live migration fails as the auto configuration of the NFS VM doesnt not work. The issue seen is that the user-data was returned with 0 bytes. This caused failure in the auto-provisioning.
Manual wget later worked. So a reboot of the VM fixed the issue.

Release note info -

The following error will be displayed on any of the compute node when the issue happens.

Workaround -
Restart the livemnfs VM '#nova stop livemnfs; nova start livemnfs'
