Virtualisation.host does not exist

Help

I have a flake like the below that I have created after reading this Tweag blog post and consulting the macos-builder flake, and the nixos-vm-on-macos flake.

    Based on https://github.com/YorikSar/nixos-vm-on-macos/blob/24025c73634e580045744c169be1be167b12fe50/flake.nix
  '';
  inputs.nixpkgs.url = github:NixOS/nixpkgs/nixos-22.05;
  #inputs.flake-utils.url = github:numtide/flake-utils;

  outputs = { self, nixpkgs, flake-utils }: {
    nixosModules = {
      vm = { modulesPath, ... }: {
        imports = [ 
          "${modulesPath}/virtualisation/qemu-vm.nix" 
        ];

        system.stateVersion = "22.05";
        
        # Configure networking
        networking.useDHCP = false;
        networking.interfaces.eth0.useDHCP = true;

        # Create user "test"
        services.getty.autologinUser = "test";
        users.users.test.isNormalUser = true;

        # Enable passwordless ‘sudo’ for the "test" user
        users.users.test.extraGroups = ["wheel"];
        security.sudo.wheelNeedsPassword = false;

        # Make it output to the terminal instead of separate window
        virtualisation.graphics = false;

        programs.nbd.enable = true;
      };
    };

    nixosConfigurations.darwinVM = nixpkgs.lib.nixosSystem {
      system = "aarch64-linux";
      modules = [
        self.nixosModules.vm
        { 
          virtualisation.host.pkgs = nixpkgs.legacyPackages.aarch64-darwin;
        }
      ];
    };

    packages.aarch64-darwin.darwinVM = self.nixosConfigurations.darwinVM.config.system.build.vm;
    packages.aarch64-darwin.default = self.packages.aarch64-darwin.darwinVM;
  };
}

When I execute nix run #.darwinVM, I get The option virtualisation.host does not exist.. What am I missing?

I figured it out!
The option is not available in the nixos-22.05 input - the above flake works when I use nixpkgs-unstable instead.
