Thanks.

A few more questions. Does the VGA emulation require VT-x? (Qemu has 
been around for a while, so I suspect not.) Could the xen console 
changes be removed and a consistent model for the console be used? (I'd 
guess the console was done the way it was because something was needed 
and it was easiest to do it the way it is done, but is it necessary now 
that the emulation code is available?) If there is a requirement that 
the text mode console talk via a xen channel to the xen tools, can it be 
done in addition to the emulation?
