I think you're right and my description was wrong, this happens before
the snapshot is created, when bdrv_image_create() opens the backing
image in order to get its size.
The command line is simply 'snapshot_blkdev virtio0 new.qcow2', the only
requirement is that the original image is opened with driver-specific
options.
