    },

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

SRST
``exit_preconfig``
  This command makes QEMU exit the preconfig state and proceed with
  VM initialization using configuration data provided on the command line
  and via the QMP monitor during the preconfig state. The command is only
  available during the preconfig state (i.e. when the --preconfig command
  line option was in use).

SRST
``block_resize``
  Resize a block image while a guest is running.  Usually requires guest
  action to see the updated size.  Resize to a lower size is supported,
  but should be used with extreme caution.  Note that this command only
  resizes image files, it can not resize block devices like LVM volumes.

    },

SRST
``drive_del`` *device*
  Remove host block device.  The result is that guest generated IO is no longer
  submitted against the host device underlying the disk.  Once a drive has
  been deleted, the QEMU Block layer returns -EIO which results in IO
  errors in the guest for applications that are reading/writing to the device.
  These errors are always reported to the guest, regardless of the drive's error
  actions (drive options rerror, werror).

SRST
``change`` *device* *setting*
  Change the configuration of a device.

  ``change`` *diskdevice* *filename* [*format* [*read-only-mode*]]
    Change the medium for a removable disk device to point to *filename*. eg::

      (qemu) change ide1-cd0 /path/to/some.iso

    *format* is optional.

    *read-only-mode* may be used to change the read-only status of the device.
    It accepts the following values:

    retain
      Retains the current status; this is the default.

    read-only
      Makes the device read-only.

    read-write
      Makes the device writable.

  ``change vnc`` *display*,\ *options*
    Change the configuration of the VNC server. The valid syntax for *display*
    and *options* are described at :ref:`sec_005finvocation`. eg::

      (qemu) change vnc localhost:1

  ``change vnc password`` [*password*]

    Change the password associated with the VNC server. If the new password
    is not supplied, the monitor will prompt for it to be entered. VNC
    passwords are only significant up to 8 letters. eg::

      (qemu) change vnc password
      Password: ********

  Physical memory dump starting at *addr*.

  *fmt* is a format which tells the command how to format the
  data. Its syntax is: ``/{count}{format}{size}``

  *count*
    is the number of items to be dumped.
  *format*
    can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
    c (char) or i (asm instruction).
  *size*
    can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
    ``h`` or ``w`` can be specified with the ``i`` format to
    respectively select 16 or 32 bit code instruction size.

  Examples:

  Dump 10 instructions at the current instruction pointer::

    (qemu) x/10i $eip
    0x90107063:  ret

SRST
``expire_password [ vnc | spice ]`` *expire-time*
  Specify when a password for spice/vnc becomes
  invalid. *expire-time* accepts:

  ``now``
    Invalidate password instantly.
  ``never``
    Password stays valid forever.
  ``+``\ *nsec*
    Password stays valid for *nsec* seconds starting now.
  *nsec*
    Password is invalidated at the given time.  *nsec* are the seconds
    passed since 1970, i.e. unix epoch.

  "in the future", i.e. at instruction counts greater than the current one.

  Automatically proceed to the instruction count *icount*, when

  snapshot and replays the execution to find the desired instruction.
  When there is no preceding snapshot or the execution is not replayed,
  then the command fails.
  *icount* for the reference may be observed with ``info replay`` command.
