And to be clear, you have custom image metadata properties that are not
part of the ImageMetaProps object? That's why they get filtered out of
the object.
Also, this is in the zvm virt driver right?
image_meta = self._image_api.get(context, image_meta.id)
And that's specifically because the zvm driver needs to get the full
image with your custom metadata properties because the ImageMetaProps
object filters them out because they aren't "registered" as properties
we (upstream nova) know about.
In that case, I'm going to close this. If you need to get the image
metadata properties into the ImageMetaProps object you'd have to propose
that upstream, but it might be hard to justify for an out of tree
driver.

Title:
image_meta code migration in finish_migraiton from older release
Status in OpenStack Compute (nova):
Invalid
Bug description:
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?
