On a recent Channel 9 video about virtualization, some Microsoft reps said they were working with 3d card makers to develop virtualizable graphics cards specifically to enable 3d effects in guest machines.

There are some practical sharing issues to have more than 1 guest be 3d accelerated (transparently). It's entirely possible that we'll see a single guest have 3d support but if virtualization-friendly cards are in the works, I'd imagine we wouldn't see much until then.

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). --

    Hi all!

    Is it likly that xen/windows/supported hardware will ever support
    full 3d acceleration of the guest os? I expect that this would be
    hard to achieve and I would love to help if I were capable! Just a
    thought anyway..

    Thanks,

    Alan
