I guess that would depend on whether the flavour has any ephemeral storage in addition to the boot volume.

The block migration should work in this case,  have you tried that.

Subject: [openstack-dev] [nova] [bug?] live migration fails with boot-from-volume

Hi,

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
fromvol
ERROR: controller is not on shared storage: Live migration can not be
used without shared storage. (HTTP 400) (Request-ID:
req-0d8da5e4-b0ec-401d-be95-d9c4f9f7e062)


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

Chris
