VFIO Passthrough on NixOS

VFIO Setup on NixOS

Disclaimer: Nobody else tested my setup so far, so this is a "works on my machine" scenario. I am not responsible for anything you break on your machine (although I'd not expect much harm).

Hardware

My system has the following hardware:

Serokell is hiring Nix DevOps Engineers

tl;dr Serokell is hiring Nix DevOps Engineers

Hi! We’re Serokell – a company with about 30 Haskellers working on a bunch of blockchain-related projects (like Cardano or TeachMePlease). We are hiring SREs and a Head of IT Operations that can work with Nix (yay Nix!) and know some Haskell. The job is fully remote.

How to set up distributed builds with nix

# If on Darwin, I recommend keeping nix stuff contained
mkdir -p /nix/etc/nix
ln -s /nix/etc/nix /etc/nix  # sysconfdir; can be overridden with $NIX_CONF_DIR

Nix UI

General notes

  • nix-channel and ~/.nix-defexpr are gone. We'll use $NIX_PATH (or user environment specific overrides configured via nix set-path) to look up packages. Since $NIX_PATH supports URLs nowadays, this removes the need for channels: you can just set $NIX_PATH to e.g. https://nixos.org/channels/nixos-15.09/nixexprs.tar.xz and stay up to date automatically.

  • By default, packages are selected by attribute name, rather than the name attribute. Thus nix install hello is basically equivalent to nix-env -iA hello. The attribute name is recorded in the user environment manifest and used in upgrades. Thus (at least by default) hello won't be upgraded to helloVariant.

    @vcunat suggested making this an arbitrary Nix expression rather than an attrpath, e.g. firefox.override { enableFoo = true; }. However, such an expression would not have a key in the user environment, unlike an attrpath. Better to require an explicit flag for this.

TBD: How to deal with search path clashes.
