Would this VT-d let us assign graphic cards to DomUs? Are we going to be able to switch between Dom0 and DomU while this card is being used?
We can talk some kind of "sharing" here, when DomU has the "screen", it uses the card, if not, Dom0. Or, somehow we should see the output of DomU in Dom0's screen, but with unmodified driver in the DomU.
Possible? or not yet even with VT-d?

And does Xen support AMD's IOMMU? I'm trying to decide on a hardware
to make some experiments with HVM and DMA transfers, but can't find
much information on which would be the best hardware onto which to try
it out. I get some information from presentations and stuff but am not
sure if they are still current or already outdated.
Thanks for your answer, it has already helped me.
