FWIW I also think c-api needs to start dropping this image property when
creating a volume as it doesn't make sense being persisted in the
volume_image_metadata once it is rotated out IMHO.

Title:
unable to boot instance from encrypted volume created from a glance
image of an encrypted volume
Status in Cinder:
New
Status in OpenStack Compute (nova):
In Progress
Bug description:
Description
===========
What the title says, plus see "steps to reproduce" below.
This is a regression caused by the fix for
https://bugs.launchpad.net/nova/+bug/1852106
Steps to Reproduce
==================
1. Let Image-1 be a "regular" (non-encrypted, bootable) image in Glance (like
the cirros image).
2. Create volume V-1 in Cinder from Image-1 specifying encrypted volume-type
T-1.
3. Boot an instance from V-1 (make sure delete-on-terminate is false). Works
fine. Delete the instance to free up the volume.
4. Call cinder upload-to-image on V-1 to create Image-2.
5. Create volume V-2 in Cinder specifying encrypted volume-type T-1 from
Image-2.
6. Boot an instance from V-2.
Expected result
===============
Working instance booted from volume.
Actual result
=============
ERROR (BadRequest): Image None is unacceptable: Direct booting of an image
uploaded from an encrypted volume is unsupported. (HTTP 400)
Note:
If we bypass the check at
https://review.opendev.org/#/c/707738/3/nova/compute/api.py@894, the instance
goes 'active' and is operable (you can ssh into it). (Of course, we don't want
to bypass the check, it just needs to be made aware that we are booting from a
volume, not trying to boot from an image.)
