37 Commit changes to the disk images (if -snapshot is used) or backing files.
38 If the backing file is smaller than the snapshot, then the backing file will be
39 resized to be the same size as the snapshot. If the snapshot is smaller than
40 the backing file, the backing file will not be truncated. If you want the
41 backing file to match the size of the smaller snapshot, you can safely truncate
42 it yourself once the commit operation successfully completes.

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

192 actions (drive options rerror, werror).

214 @end example

218 @var{read-only-mode} may be used to change the read-only status of the device.
219 It accepts the following values:
221 @table @var
222 @item retain
223 Retains the current status; this is the default.
225 @item read-only
226 Makes the device read-only.
228 @item read-write
229 Makes the device writable.
230 @end table
232 @item change vnc @var{display},@var{options}
233 Change the configuration of the VNC server. The valid syntax for @var{display}

236 @example
237 (qemu) change vnc localhost:1
238 @end example
240 @item change vnc password [@var{password}]
242 Change the password associated with the VNC server. If the new password is not
243 supplied, the monitor will prompt for it to be entered. VNC passwords are only
244 significant up to 8 letters. eg
