Re: [Xen-users] Getting ready for a computer build for IOMMU virtualization, need some input regarding sharing multiple GPUs among VMs

For GTX480 to Quadro 6000 you can an find an short description  I wrote here (not well documented).

Everything is a bit new for me. My understanding is a bit limited. So I wrote it as I understood

The hardware mod part is quite well documented here:
http://www.eevblog.com/forum/chat/hacking-nvidia-cards-into-their-professional-counterparts/

It's a fairly epic thread, but well worth a read. Relevant if you are
looking to mod a GTX680/690/770 into a Quadro K5000 or Grid K2.

If you are looking to mod a GTS450/GTX470/GTX480, you can do so with by
changing the strapping bits and device ID in the BIOS. I haven't gotten
around to writing it up yet, unfortunately. I will post here when I have.
