## Error cause
`{'code': 400, 'created': '2025-02-10T10:38:39Z', 'message': 'Instance 44240d84-52ca-4474-b4ac-163bd1ba2def cannot be rescued: Driver Error: Image 9115b741-6eb3-4574-894d-9f2e28600ff8 could not be found.'}`

Likely a deleted snapshot!

## Notes on specific case
44240d84-52ca-4474-b4ac-163bd1ba2def instance_system_metadata geupdate maar alleen het image_base_image_ref geupdatet.
De rest van de image metadata is nog alsof het het oude snapshot.
Misschien kunnen we nova-manage gebruiken om het te updaten:
```
[jasras@n07.compute.prv.vps1-testpod-cph3.one.com ~]$ sudo nova-manage image_property set --help
Modules with known eventlet monkey patching issues were imported prior to eventlet monkey patching: urllib3. This warning can usually be ignored if the caller is only importing and not executing nova code.
usage: nova-manage image_property set [-h] [--property <image_property>] <instance_uuid>

Set the values of instance image properties stored in the database. This is only allowed for instances with a STOPPED, SHELVED or SHELVED_OFFLOADED vm_state.

positional arguments:
  <instance_uuid>       UUID of the instance

options:
  -h, --help            show this help message and exit
  --property <image_property>
                        Image property to set using the format name=value. For example: --property hw_disk_bus=virtio --property hw_cdrom_bus=sata

```
