looking at the code, I see this in gnu/image.scm: (define-record-type* <image> image make-image image? (name image-name ;symbol (default #false)) (format image-format ;symbol (sanitize validate-image-format)) ... and a bit above: ;; The supported image formats. (define-set-sanitizer validate-image-format format (disk-image compressed-qcow2 docker iso9660 tarball wsl2)) So my guess is that 'compressed-qcow2 would be the value to put there. Andreas
