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

Remove host block device. The result is that guest generated IO is no longer
|
|
submitted against the host device underlying the disk. Once a drive has
|
|
been deleted, the QEMU Block layer returns -EIO which results in IO
|
|
errors in the guest for applications that are reading/writing to the device.
|
|
These errors are always reported to the guest, regardless of the drive's error
|
|
actions (drive options rerror, werror).

@example

(qemu) change ide1-cd0 /path/to/some.iso
|

@var{format} is optional.

@var{read-only-mode} may be used to change the read-only status of the device.
|

It accepts the following values:
|

@table @var
|
|
@item retain
|
|
Retains the current status; this is the default.
|
|
|

|
|
Makes the device read-only.
|

|
|
Makes the device writable.
|

@end table
|

and @var{options} are described at @ref{sec_invocation}. eg
|
|
|
|
@example
|
|
(qemu) change vnc localhost:1
|
|
@end example
|
|
|
|
@item change vnc password [@var{password}]
|
|
|
|
Change the password associated with the VNC server. If the new password is not
|
|
supplied, the monitor will prompt for it to be entered. VNC passwords are only
|
|
significant up to 8 letters. eg
|
|
|
|
@example
|
|
(qemu) change vnc password
|
|
Password: ********
