Is it possible to use VT-d to dedicate two nvidia graphics cards that support SLI (using a motherboard that also supports SLI and vt-d) to a guest OS, and use the nvidia driver in the guest to enable/use SLI? I noticed that Parallels supports nvidia 'SLI Multi-OS', not sure if it's what I'm looking for or not (and it only appears to be supported on a small number of Quadro cards)
