I was just testing the current icehouse code and came across some 
behaviour that looked suspicious.

I have two nodes, an all-in-one and a compute node.  I was not using 
shared instance storage.

I created a volume from an image and then booted an instance from the 
volume.  Once the image was up and running I tried to do a "nova 
live-migration <instance>" and got the following error:

cfriesen at controller:/opt/stack/nova/nova/compute$ nova live-migration 
ERROR: controller is not on shared storage: Live migration can not be 
used without shared storage. (HTTP 400) (Request-ID: 

Shouldn't booting from volume count as a form of shared storage?
