# Declarative Home Assistant VM configuration using NixVirt.
|

# This is the permanent, declarative solution to managing your VM.

#
|
||||
# To use this, you must:
|
||||
# 1. Add NixVirt to your flake.nix inputs.
|
||||
# inputs.nixvirt = {
|
||||
# url = "github:NixOS/nixvirt";
|
||||
# inputs.nixpkgs.follows = "nixpkgs";
|
||||
# };
|
||||
# 2. Import this file and the nixvirt module in your main NixOS configuration:
|
||||
# imports = [
|
||||
# ./modules/vms/haos-vm.nix
|
||||
# inputs.nixvirt.nixosModules.default # Provides the options below
|
||||
# ];
|
||||
# 3. Remove the old `services.homeassistant-vm` block from your configuration.
|
||||
# 4. Ensure `virtualisation.libvirtd.qemu.ovmf.enable = true;` is set.
