@item --force-share (-U)

If specified, @code{qemu-img} will open the image in shared mode, allowing

other QEMU processes to open it in write mode. For example, this can be used to

get the image information (with 'info' subcommand) when the image is used by a

running guest.  Note that this could produce inconsistent results because of

concurrent metadata changes, etc. This option is only allowed when opening

images in read-only mode.



@item --backing-chain

will enumerate information about backing files in a disk image chain. Refer

below for further description.
