Thanx alot, Mark.
I am wondering if device management, like vga, would share the same
architecture as block device?
if that is the case, would vga be accessed by guest os directly?
if that is not the case, shall we have to base it on X11 system?
if all above is wrong, will u please give me some outline of the device
achitecture?

Yes, that's all correct.

A fully virtualised environment will be available for guests on a VT CPU, so
they won't *need* any modifications in order to run. However, for good IO
performance, you're likely to want to install Xen-aware device drivers which
will be compatible with the existing frontend/backend scheme.
Other fully virtualised environments (e.g. VMWare) also sometimes provide
higher-performance drivers that are aware of the environment. In Xen's case
we have Xen-aware drivers already but they need to be adapted to run in a VT
virtual machine
HTH,
