Public bug reported:
we had some problem when migrate from older release from L to N (it's
not kvm driver)
we had this error in virt layer in finish_migration function when we use
following code in virt layer's finish_migration
image_meta = self._image_api.get(context, image_meta.id)

so the problem is seems we didn't have image_meta.id set if it's an old
instance because old instance image_meta comes from system_metadata, I
think this image.id should be set when we create ImageMeta in any case?
