Public bug reported: when we try to live migrate an instance, we get available host list. however, we fail on cpu compatibility.
It would be good if we can filter hosts so that user's cannot migrate instances to hosts that are incompatible. I opened a ticket for novacli to create a query for host compatibility which horizon can use: https://bugs.launchpad.net/python-novaclient/+bug/1379385 here is the error we would get when trying to
