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

195 submitted against the host device underlying the disk. Once a drive has
196 been deleted, the QEMU Block layer returns -EIO which results in IO
197 errors in the guest for applications that are reading/writing to the device.

199 actions (drive options rerror, werror).

243 passwords are only significant up to 8 letters. eg::

462``xp /``\ *fmt* *addr*

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

1817``replay_break`` *icount*
1818 Set replay breakpoint at instruction count *icount*.
1819 Execution stops when the specified instruction is reached.
1820 There can be at most one breakpoint. When breakpoint is set, any prior
1821 one is removed. The breakpoint may be set only in replay mode and only
1822 "in the future", i.e. at instruction counts greater than the current one.
1823 The current instruction count can be observed with ``info replay``.

1849``replay_seek`` *icount*
1850 Automatically proceed to the instruction count *icount*, when
1851 replaying the execution. The command automatically loads nearest
1852 snapshot and replays the execution to find the desired instruction.
1853 When there is no preceding snapshot or the execution is not replayed,
1854 then the command fails.
1855 *icount* for the reference may be observed with ``info replay`` command.
