HXCOMM Use DEFHEADING() to define headings in both help text and texi
HXCOMM Text between STEXI and ETEXI are copied to texi version and
HXCOMM discarded from C version
HXCOMM DEF(command, args, callback, arg_string, help) is used to construct
HXCOMM monitor commands

@item block_resize
@findex 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.

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.

Change the configuration of a device.

@table @option
@item change @var{diskdevice} @var{filename} [@var{format}]
Change the medium for a removable disk device to point to @var{filename}. eg

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

@var{format} is optional.

@item change vnc @var{display},@var{options}
Change the configuration of the VNC server. The valid syntax for @var{display}
and @var{options} are described at @ref{sec_invocation}. eg

@example
(qemu) change vnc localhost:1
@end example

@item change vnc password [@var{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

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

Physical memory dump starting at @var{addr}.

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

@table @var
@item count
is the number of items to be dumped.

@item format
can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
c (char) or i (asm instruction).

@item size
can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
@code{h} or @code{w} can be specified with the @code{i} format to
respectively select 16 or 32 bit code instruction size.

@end table

Examples:
@itemize
@item
Dump 10 instructions at the current instruction pointer:
@example
(qemu) x/10i $eip

Send @var{keys} to the emulator. @var{keys} could be the name of the
key or @code{#} followed by the raw value in either decimal or hexadecimal
format. Use @code{-} to press several keys simultaneously. Example:
@example
sendkey ctrl-alt-f1
@end example

This command is useful to send keys that your graphical user interface
intercepts at low level, such as @code{ctrl-alt-f1} in X Window.
