Re: [Xen-users] 3D acceleration

[Anthony Liguori <aliguori@xxxxxxxxxx>]

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.
