The following common options can be placed before or after the sub-command: --disk=uuid|filename Either the UUID or filename of a harddisk image, e.g. VDI, VMDK, VHD, ++. --dvd=uuid|filename Either the UUID or filename of a DVD image, e.g. ISO, DMG, CUE. --floppy=uuid|filename Either the UUID or filename of a floppy image, e.g. IMG. --password-file=-|filename The name of a file containing the medium encryption password. If - is specified, the password will be read from stdin. Formats a floppy medium with the FAT file system. This will erase the content of the medium. --quickQuickformat the medium. Dumps the medium content to stdout or the specified file. --hexDump as hex bytes. --offsetThe byte offset in the medium to start. --sizeThe number of bytes to dump. --output The output filename. As usual - is take to mean stdout. Converts the medium to a streamable format and dumps it to the given output. --formatThe format of the destination image. --variantThe medium variant for the destination. --output The output filename.
