Sounds like it'll probably work.  We know the driver domains stuff works, so 
there's no reason for this not to.

There's one caveat to using the PCI device driver domain stuff - if you give a 
domain access to a device, all processes in that domain can (if they try) 
acescs it directly.  This is due to the way we use x86 features to control IO 
port access and doesn't really matter as long as you trust the processes in 
the domains :-)  Changing this behaviour is a fairly small amount of code but 
we haven't needed it with dedicated driver domains.

Glad to hear it!  Give us 1-2 weeks to get Xen 2.0 finally released, then I'll 
get back to this code.   When I've got things into a sane state, I'll check 
them in to xeno-unstable and you can try it out...


On a related node, are you the brave chap who was trying to get a domain to 
drive its own monitor?  How did that go?  Did Ian's suggestion (about getting 
X to be less polite about virtual terminals) work?  It'd be really 
interesting to get this going...
