33 Commit changes to the disk images (if -snapshot is used) or backing files.
34 If the backing file is smaller than the snapshot, then the backing file
35 will be resized to be the same size as the snapshot. If the snapshot is
36 smaller than the backing file, the backing file will not be truncated.
37 If you want the backing file to match the size of the smaller snapshot,
38 you can safely truncate it yourself once the commit operation successfully

87 action to see the updated size. Resize to a lower size is supported,
88 but should be used with extreme caution. Note that this command only
89 resizes image files, it can not resize block devices like LVM volumes.

205 errors in the guest for applications that are reading/writing to the device.

471
472 *fmt* is a format which tells the command how to format the
473 data. Its syntax is: ``/{count}{format}{size}``
474
475 *count*
476 is the number of items to be dumped.
477 *format*
478 can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
479 c (char) or i (asm instruction).
480 *size*
481 can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
482 ``h`` or ``w`` can be specified with the ``i`` format to
483 respectively select 16 or 32 bit code instruction size.
