WARNING: Image format was not specified for 'json:{"fat-type": 0, "backing": {"driver": "vvfat_write_target"}, "dir": "LoaderPkg/ESP", "driver": "vvfat", "floppy": false, "rw": true, "write-target": {"driver": "qcow", "file": {"driver": "file", "filename": "/var/folders/sw/2r7j_qps1g30rjp3rw6v44r80000gn/T//vl.sjRmTn"}}}' and probing guessed raw.
         Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.
