32``commit``
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
39 completes.

85``block_resize``
86 Resize a block image while a guest is running. Usually requires guest
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.

392 This slows down emulation a lot, but can be useful in some situations,
393 such as when trying to analyse the logs produced by the ``-d`` option.
394 This only has an effect when using TCG, not with KVM or other accelerators.
395
396 If called with option off, the emulation returns to normal mode.

486``xp /``\ *fmt* *addr*
487 Physical memory dump starting at *addr*.
488
489 *fmt* is a format which tells the command how to format the
490 data. Its syntax is: ``/{count}{format}{size}``
491
492 *count*
493 is the number of items to be dumped.
494 *format*
495 can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
496 c (char) or i (asm instruction).
497 *size*
498 can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
499 ``h`` or ``w`` can be specified with the ``i`` format to
500 respectively select 16 or 32 bit code instruction size.
