This updates the documentation for commiting snapshot images. Specifically, this highlights what happens when the base image is either smaller or larger than the snapshot image being committed. In the case of the base image being smaller, it is resized to the larger size of the snapshot image. In the case of the base image being larger, it is not resized automatically, but once the commit has completed it is safe for the user to truncate the base image.

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).

@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
