Public bug reported:

When upgrading Openstack, we need backup the vm, and restore them in new version of openstack. so we may need to save
the vm snapshot image named by its vm uuid.

If we "glance image-create" the vm image, and name it with "uuid", then delete it, there will be failure message:
Request returned failure status.

But it indeed "removed"  the vm. ( marked as "deleted" in database).

The message should not be emitted.


step to reproduce:

1. create a image, and assign the name with a 'uuid'.

# glance image-create --name 5d5b7329-2f89-4cba-a6cc-5d4b49330d3b  --file 5d5b7329-2f89-4cba-a6cc-5d4b49330d3b   --disk-format=qcow2 --container-format=bare --is-public True
