PCI Passthrough

Warning: unfinished (but successfull!)

I did PCI passthrough on Archlinux and Debian with the old PCI-stub method (this was pre-4.0 era). And later I did PCI passthrough on the 4.1+ kernels on Arch and Ubuntu (16.10 I think?).

This is my attempt at doing the same on Nixos.

Requirements

NixOS on Fedora

Please note that these instructions are not offically supported or condoned by Nix and are not guaranteed to always work, but from my testing everything seems to work perfectly fine.

These steps may not be required if NixOS/nix#2374 is resolved.

SELinux

These commands are required for both Fedora Workstation and Fedora Silverblue
