## Installing a playground VM I've used gnome-boxes from my current Fedora laptop for running playground vm's. Settings: ISO: nixos-minimal Hard drive: 32GB RAM: 2GB EFI: Enable Expose port 22 to allow ssh into vm (host port 3022, guest 22) ```sh # set temp root passwd sudo su passwd ``` `sshd` is already running, so you can now ssh into the vm remotely for the rest of the setup. `ssh root@127.0.0.1 -p 3022` ```sh # Partitioning parted /dev/sda -- mklabel gpt parted /dev/sda -- mkpart root ext4 512MB -8GB parted /dev/sda -- mkpart swap linux-swap -8GB 100% parted /dev/sda -- mkpart ESP fat32 1MB 512MB parted /dev/sda -- set 3 esp on # Formatting mkfs.ext4 -L nixos /dev/sda1 mkswap -L swap /dev/sda2 mkfs.fat -F 32 -n boot /dev/sda3 # Mounting disks for installation mount /dev/disk/by-label/nixos /mnt mkdir -p /mnt/boot mount /dev/disk/by-label/boot /mnt/boot swapon /dev/sda2 # Generating default configuration nixos-generate-config --root /mnt ``` From this config copy the bootstrap configuration and fetch the hardware configuration. ```sh scp -P 3022 nixos/hosts/bootstrap/configuration.nix root@127.0.0.1:/mnt/etc/nixos/configuration.nix scp -P 3022 root@127.0.0.1:/mnt/etc/nixos/hardware-configuration.nix nixos/hosts/nixosvm/hardware-configuration.nix ``` Then back to the VM ```sh nixos-install reboot nixos-rebuild switch ``` Set the password for the user that was created. ```sh passwd truxnell ``` Also grab the ssh keys and re-encrypt sops Login as user, copy nix git ```sh mkdir .local cd .local git clone https://github.com/szinn/nix-config.git cd nix-config ``` Apply config to bootstrapped device First time around, MUST APPLY with name of host in ./hosts/ This is because `.. --flake .` looks for a `nixosConfigurations` key with the machines hostname The bootstrap machine will be called 'nixos-bootstrap' so the flake by default would resolve `nixosConfigurations.nixos-bootstrap` Subsequent rebuilds can be called with the default command as after first build the machines hostname will be changed to the desired machine ```sh nixos-rebuild switch --flake .# ```
