# HG changeset patch

# Node ID 91555131e235f814e68179dc5ffd6b698be882be

libxenlight: implement cdrom insert/eject
This patch implements functions in libxenlight to change the cdrom in
a VM at run time and to handle cdrom eject requests from guests.
This patch adds two new commands to xl: cd-insert and cd-eject; it
also modifies xl to handle cdrom eject requests coming from guests
(actually coming from qemu).
