KVM GPU Passthrough on MSI H97 Gaming 3

Hello Arch Community!

I recently stumbled upon Virtualization in Linux with GPU passthrough to be able to play games in a VM. After I read about it I began trying to set my system up but hit one obstacle after the other
Right now I tried a list of guides (https://www.reddit.com/r/pcmasterrace/comments/2z0evz/gpu_passthrough_or_how_to_play_any_game_at_near/ - the one that got me started, https://bbs.archlinux.org/viewtopic.php?id=162768 - which is basically the same guide, https://www.pugetsystems.com/labs/artic … 4-KVM-585/ - I tried Ubuntu after failing in Arch, http://apurv.me/vga-passthrough-using-k … ntu-14-04/ - and I tried blacklisting the Radeon driver). My setup consists of a Xeon E3 1231v3, a MSI H97 Gaming 3, an AMD HD 6870 (from MSI i think...Reference Design) and an old NVIDIA GT430. My goal would be to have the AMD card passed through but any achievements would be great for now!

I found out, that my GPU plugged into the first PCIe Slot can't be blacklisted since then my system stops booting at "starting version 219" and so far I couldn't figure out why. The Problem is, I can't just plug my card into my second slot since then it's in an IOMMU Group with both my onboard-Network card and my PCI WiFi card which would require me to isolate all of them. I read about the ACS downstream patch but I'm not sure whether I just failed to set it up correctly or it did not work for me.

Can someone help me with either splitting the IOMMU group or with blocking my first PCIe slot (only device in that group)?

Is an EFI Flash for my HD 6870 required to work? I read that you need an EFI supporting card for the vfio method but what about the pci-stub method. Does that work without me flashing my card?
