Hello guys,
I'm trying to make a two headed machine with kvm and vga passthrough following this guide http://turlucode.com/qemu-kvm-on-arch-l … ide/#tab-1. According to the guide I have to install linux-vfio kernel because i have two gtx 970's.
The problem is that when i try to boot into the kernel I get a blackscreen and can't do anything about it. Any ideas?
Greetings,
Gl3nn
edit: found it. For everyone else who is having this problem you need to install nvidia-dkms and the linux-headers with Yaourt.

You don't have to install linux-vfio because you have two 970's. The only reason you might need that kernel is if you have IOMMU grouping problems (which is why that step explicitly says 'if needed' and includes commands to check that).
I'm running two 970's as well and I've never needed any custom kernels or custom kernel patches to accomplish GPU passthrough.
Note, there is a whole article about this on the Arch wiki as well; https://wiki.archlinux.org/index.php/PC … h_via_OVMF

Yes that's correct sorry for leaving that out. I indeed need the patch for the iommu grouping problem.

It's bad enough that guide doesn't mention there are plenty of alternatives for yaourt.
Please don't make it worse by advocating yaourt for things pacman is responsible for.
nvidia-dkms is in repos.
Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

Could you explain why yaourt is worse then pacman?

Every time someone uses Yaourt, God kills a kitten.
But seriously, it is a tool. But, like all tools -- Tesla Autopilots, firearms, chainsaws, surface planers, Linotype -- if you don't know what you are doing and don't understand the basics, things are not going to end well.
There are also better tools for the job. https://wiki.archlinux.org/index.php/AUR_helpers . Hint: more green, the better.
