So I’m on the look for a new motherboard, since the second PCIx16 slot died on my current board.
I google’d a bit for some decent motherboards and found the MSI Z270 Gaming Pro Carbon, and proceeded to order it. There is just one thing, however. It places both of my GPUs in the same IOMMU group, hindering in my tracks to a perfect setup.
I’ve tried to apply the ACS patch to fix this, but I’m some trouble with that. It seems to mess with libvirt, causing it freeze and never boot my Windows VM.
So in short, does anyone have any recommendations for a motherboard with decent IOMMU groupings with graphics cards plugged in? I’m using an RX 550 for the host and a GTX 1070 for Windows guest.
