Assuming you're using the Libvirt driver, a hackaround here is to cold
migrate the instance to another host, this refreshes the connection_info
from c-api and should allow the instance to boot correctly.

Indeed I hadn’t thought of this. If migrations updates the block_device_mapping from the cinder DB entry, I will not need to make any database modifications.

Thank you for your help, it’s strongly appreciated.
