66
Resize a block image while a guest is running.  Usually requires guest
67
action to see the updated size.  Resize to a lower size is supported,
68
but should be used with extreme caution.  Note that this command only
69
resizes image files, it can not resize block devices like LVM volumes.

140
Remove host block device.  The result is that guest generated IO is no longer
141
submitted against the host device underlying the disk.  Once a drive has
142
been deleted, the QEMU Block layer returns -EIO which results in IO
143
errors in the guest for applications that are reading/writing to the device.

161
@item change @var{diskdevice} @var{filename} [@var{format}]
162
Change the medium for a removable disk device to point to @var{filename}. eg
163

    
164
@example
165
(qemu) change ide1-cd0 /path/to/some.iso

@var{format} is optional.
169

    
170
@item change vnc @var{display},@var{options}
171
Change the configuration of the VNC server. The valid syntax for @var{display}
172
and @var{options} are described at @ref{sec_invocation}. eg
173

    
174
@example
175
(qemu) change vnc localhost:1
176
@end example
177

    
178
@item change vnc password [@var{password}]
179

    
180
Change the password associated with the VNC server. If the new password is not
181
supplied, the monitor will prompt for it to be entered. VNC passwords are only
182
significant up to 8 letters. eg
183

    
184

@var{fmt} is a format which tells the command how to format the
410
data. Its syntax is: @option{/@{count@}@{format@}@{size@}}
411

    
412
@table @var
413
@item count
414
is the number of items to be dumped.
415

    
416
@item format
417
can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
418
c (char) or i (asm instruction).
419

    
420
@item size
421
can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
422
@code{h} or @code{w} can be specified with the @code{i} format to
423
respectively select 16 or 32 bit code instruction size.
