I like the request for Graphics in DomU. How do you want to run a
Xen-System on a laptop maybe? The Dom0-Kernel shouldn't have ANY contact
with the users itself due to security reasons. (too much software that
could be possible security holes)

Another point is: When you run a Xen-System that runs at home to solve
several issues at once (internal file server, firewall, music
station/browser/whatever) you are very fast at the point that you CAN
use the PC in console mode (xm console DomU-Name) But that is a security
 hole per default because you need to be admin to do that. So basically
if you want to run a xenified server that should NOT be a dedicated one
(without monitor) you get serious trouble if you want to use that
computer as a "normal" PC as well.  When you can't remap the graphic
card, you don't have "normal consoles" or "normal X-Window" that is
secure enough to esure, that it can't harm the other VMs running...

So having an option that remaps the graphic card and hands it over to a
VM that then takes over the whole graphic output (dom0 only reachable
using SSH or serial console or something) would make quite some sense
security wise  ;)
