Open Stack

Hi Ignazio,

I am trying to evacuate the compute host on older version (mitaka).
Could please share the process you followed. I am not able to succeed with
openstack live-migration fails with error message (this is known issue in
older versions) and nova live-ligration - nothing happens even after
initiating VM migration. It is almost 4 days.

~Jay.
