LXC configuration.nix builds but does not install load

1

Running nixos-rebuild switch or

[root@nixos:~]# nixos-rebuild switch -I nixos-config=/etc/nixos/configuration.nix
building Nix...
building the system configuration...

[root@nixos:~]#

Does not do anything. I have created a configuration.nix using a guide but it does not work

{ modulesPath, config, pkgs, ... }:

  imports =
    [
      # Include the default lxc/lxd configuration.
      "${modulesPath}/virtualisation/lxc-container.nix"
      # Include the container-specific autogenerated configuration.
      ./terminal-base.nix
      #./lxd.nix - this has to be commented out from the system tarball
    ];

  # I had to suppress these units, since they do not work inside LXC
