Well, we can't change the default back, because that would not be secure.

There's xm block-configure which lets you switch CD-ROM files.

And there's a few things which could be done to further improve things:
- plumb through the monitor option to the domain config file and the
xend config file
- fix xm console so it can connect to the monitor pty
- add an xm send-key command
