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.

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

125 @end example
127 @var{format} is optional.

134 (qemu) change vnc localhost:1
135 @end example
137 @item change vnc password [@var{password}]
139 Change the password associated with the VNC server. If the new password is not
140 supplied, the monitor will prompt for it to be entered. VNC passwords are only
141 significant up to 8 letters. eg

359 is the number of items to be dumped.
361 @item format
362 can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
363 c (char) or i (asm instruction).
365 @item size
366 can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
367 @code{h} or @code{w} can be specified with the @code{i} format to
368 respectively select 16 or 32 bit code instruction size.
