Howdy,

The following patch allows the change monitor command to be used with 
vnc, serial, and parallel devices.  It depends on my previously posted 
patches.

The patch implements:

1) A vnc "null" display
2) The ability to reopen character devices
3) Appropriate tab expansions for devices

This patch is quite useful for management tools as it allows much more 
flexibility in allowing the user to configure running instances.

Regards,

Anthony Liguori
