Re: [Xen-users] 3D acceleration

Is it possible to use my motherboard's integrated graphics for dom0 and my
x1900 video card for a guest?  If so, how would I set this up?

There's been more than one discussion thread on this subject, and the
summary answer is:
- It's possible to do with a para-virtualized driver in the guest - that is,
a driver that takes the calls for graphics commands and passes them to Dom0,
where a "real" graphics driver executes the actual intention of the call. 
 
It is not trivial to write such a driver, but it's nowhere near as hard as
it would be to try to get a very advanced native driver to work in a guest
environment.
 
Of course, if you have two different graphics cards in the machine, Dom0 can
be given one card, and one of the guest domains can be given the other card,
thus you can use the native driver straight off (at least in fully
virtualized mode). 
 
Can you do this one card?  Just have dom0 not have a video card, and pass
the only video card to domU?  That's how I run all my servers anyway, and
it'd be awesome to use hardware acceleration on a "desktop domU"...
