[Bug 1482040] [NEW] rebuild volume-backed instance with image
Public bug reported:
When rebuild an volume-backed instance using normal images from glance,
nothing will be changed for the instance after rebuild except the image name
will be added to the instance, the instance is actually again built using the same
volume.
