Hi!

Then you'll be happy to here that this functionality is moving
outside Xen and into a 'driver domain' in the new IO model.
Do you mean that (in a very simple view) Xen will take care of memory
and domain management and another domain (domain 0?) will take care of
every other piece of hardware like IDE, SCSI and NICs?
This would be very cool but, as I understand. Xen requires "hardware"
drivers to be event based, so the guest OS in domain 0 would need a
giant patch... Right?
And Xen will end up with a) the Xen core, b) "hardware domain" guest OS
patch and c) general guest patches. Now we have a) and c), only... :-)
Making the core small is very good, but enlarging the rest - the "guest"
universe - is not so good...
Maybe I didn't understand your sentence :-) Can you explain a bit more,
please? :-)
Thanks,
Nuno Silva
