[Openstack-operators] [glance] Modify image so it creates a Cinder volume as its root vol when launched

HI all;
I've finally come up with a good strategy to migrate between images and
volumes.  (Had to hack my system a little as per previous mail.)

When I upload a cinder volume to an image, it creates an image that then
produces an instance where the root volume is on the compute node.  This is
often Ok, but I've somehow in the past produced images that automatically
create root volumes on Cinder.

How can I modify an image such that it creates root on Cinder when an
instance is spun up?   How can I switch back if I want?
I'm sure this is a common new question.  :-)
