I cannot confirm this for every use case, but I've done some recent testing with VFIO on an old kernel for an unrelated patch, and I noticed that if I used kernel 3.6, all my physical ports were assigned the same IOMMU group (as opposed to different ones with a more recent kernel). So I think it's a safe bet to at least try and test this on your side :) Thanks, Anatoly
