Steps to reproduce

Add to your configuration.nix

    # Enable Virtualbox
    virtualisation.virtualbox.host.enable = true;
    boot.kernelPackages = pkgs.linuxPackages // {
        virtualbox = pkgs.linuxPackages.virtualbox.override {
            enableExtensionPack = true;
            pulseSupport = true;
        };
    };
    nixpkgs.config.virtualbox.enableExtensionPack = true;

Switch to nixos unstable channel and run

nixos-rebuild boot --upgrade

Oh, boo, did Oracle re-release the extPack?! -.- I'll take a look when I have a moment
