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.

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

461 *fmt* is a format which tells the command how to format the
462 data. Its syntax is: ``/{count}{format}{size}``
463
464 *count*
465 is the number of items to be dumped.
466 *format*
467 can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
468 c (char) or i (asm instruction).
469 *size*
470 can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
471 ``h`` or ``w`` can be specified with the ``i`` format to
472 respectively select 16 or 32 bit code instruction size.

1813``replay_break`` *icount*
1814 Set replay breakpoint at instruction count *icount*.
1815 Execution stops when the specified instruction is reached.
1816 There can be at most one breakpoint. When breakpoint is set, any prior
1817 one is removed. The breakpoint may be set only in replay mode and only
1818 "in the future", i.e. at instruction counts greater than the current one.
1819 The current instruction count can be observed with ``info replay``.

1832 Remove replay breakpoint which was previously set with ``replay_break``.
1833 The command is ignored when there are no replay breakpoints.

1845``replay_seek`` *icount*
1846 Automatically proceed to the instruction count *icount*, when
1847 replaying the execution. The command automatically loads nearest
1848 snapshot and replays the execution to find the desired instruction.
1849 When there is no preceding snapshot or the execution is not replayed,
1850 then the command fails.
1851 *icount* for the reference may be observed with ``info replay`` command.
