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. Berto
