@item block_resize

67
Resize a block image while a guest is running.  Usually requires guest
68
action to see the updated size.  Resize to a lower size is supported,
69
but should be used with extreme caution.  Note that this command only
70
resizes image files, it can not resize block devices like LVM volumes.

@item drive_del @var{device}
100
@findex drive_del
101
Remove host block device.  The result is that guest generated IO is no longer
102
submitted against the host device underlying the disk.  Once a drive has
103
been deleted, the QEMU Block layer returns -EIO which results in IO
104
errors in the guest for applications that are reading/writing to the device.

123
@item change @var{diskdevice} @var{filename} [@var{format}]
124
Change the medium for a removable disk device to point to @var{filename}. eg
125

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

@var{format} is optional.
131

    
132
@item change vnc @var{display},@var{options}
133
Change the configuration of the VNC server. The valid syntax for @var{display}
134
and @var{options} are described at @ref{sec_invocation}. eg
135

    
136
@example
137
(qemu) change vnc localhost:1
138
@end example
139

    
140
@item change vnc password [@var{password}]
141

    
142
Change the password associated with the VNC server. If the new password is not
143
supplied, the monitor will prompt for it to be entered. VNC passwords are only
144
significant up to 8 letters. eg
145

    
146
@example
147
(qemu) change vnc password

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

359

    
360
@table @var
361
@item count
362
is the number of items to be dumped.
363

    
364
@item format
365
can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
366
c (char) or i (asm instruction).
367

    
368
@item size
369
can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
370
@code{h} or @code{w} can be specified with the @code{i} format to
371
respectively select 16 or 32 bit code instruction size.

forever.  @var{action-if-connected} specifies what should happen in
1240
case a connection is established: @var{fail} makes the password change
1241
fail.  @var{disconnect} changes the password and disconnects the
1242
client.  @var{keep} changes the password and keeps the connection up.
1243
@var{keep} is the default.
