@item block_resize

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.

@item drive_del @var{device}
99
@findex drive_del
100
Remove host block device.  The result is that guest generated IO is no longer
101
submitted against the host device underlying the disk.  Once a drive has
102
been deleted, the QEMU Block layer returns -EIO which results in IO
103
errors in the guest for applications that are reading/writing to the device.

121
@table @option
122
@item change @var{diskdevice} @var{filename} [@var{format}]
123
Change the medium for a removable disk device to point to @var{filename}. eg
124

    
125
@example
126
(qemu) change ide1-cd0 /path/to/some.iso
127

@var{format} is optional.
130

    
131
@item change vnc @var{display},@var{options}
132
Change the configuration of the VNC server. The valid syntax for @var{display}
133
and @var{options} are described at @ref{sec_invocation}. eg
134

    
135
@example
136
(qemu) change vnc localhost:1
137
@end example
138

    
139
@item change vnc password [@var{password}]
140

    
141
Change the password associated with the VNC server. If the new password is not
142
supplied, the monitor will prompt for it to be entered. VNC passwords are only
143
significant up to 8 letters. eg
144

    
145
@example
146
(qemu) change vnc password

@var{fmt} is a format which tells the command how to format the

358

    
359
@table @var
360
@item count
361
is the number of items to be dumped.
362

    
363
@item format
364
can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
365
c (char) or i (asm instruction).
366

    
367
@item size
368
can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
369
@code{h} or @code{w} can be specified with the @code{i} format to
370
respectively select 16 or 32 bit code instruction size.
