Public bug reported:
Hi there,
I have configured controller node (controller) and two compute nodes
(compute 1 and compute 2) using icehouse openstack on three virtual
machines which run Ubuntu 14.04 LTS.
I'm trying to live migrate one instance from compute1 to compute2
through dashboard/command-line and I got migration error and the status
of the instance is 'migrating'
I check the log /var/log/nova/nova-conductor.log and I got the
following:
ERROR oslo.messaging._drivers.common [-] Returning exception Migration error:
