+# Incus NixOS VM
+
+Provision a NixOS KVM virtual machine on an [Incus](https://linuxcontainers.org/incus/) host. The image is pulled from [images.linuxcontainers.org](https://images.linuxcontainers.org) and cached on the host.
+
+NixOS does not support cloud-init. This template uses `nixos-rebuild switch` via `incus exec` to configure the workspace user and start the Coder agent. The rebuild only runs on first boot; subsequent starts rotate the agent token and restart the service directly.
+
+## Prerequisites
+
+### 1. Install Incus on the VM host
+
+Follow the [Incus installation guide](https://linuxcontainers.org/incus/docs/main/installing/) for your distro. On Debian/Ubuntu:
+
+```sh
+sudo apt-get install incus
+sudo incus admin init
+```
+
+### 2. Run the Coder provisioner on the same machine
+
+This template uses the local Incus socket, so the Coder provisioner must run on the same machine as Incus. See [provisioner daemons](https://coder.com/docs/admin/provisioners).
+
+### 3. Ensure the host has KVM
+
+```sh
+ls /dev/kvm
+```
+
+If the device is missing, enable virtualisation in your BIOS/UEFI or, in a nested setup, pass through the `kvm` module.
+
+### 4. Create a storage pool (if needed)
+
+```sh
+incus storage create default btrfs
+incus storage list
+```
+
+### 5. Push the template
+
+```sh
+# amd64 host:
+coder templates push incus-nixos --directory . --variable arch=amd64
+
+# arm64 host:
+coder templates push incus-nixos --directory . --variable arch=arm64
+```
+
+The `storage_pool` variable defaults to `default`. Override if needed:
+
+```sh
+coder templates push incus-nixos --directory . \
+  --variable arch=arm64 \
+  --variable storage_pool=fast-nvme
+```
+
+The `nixos_channel` variable controls which NixOS channel is used for `nixos-rebuild`. It must match the image version (default: `nixos-25.11`).
+
+## Usage
+
+1. Create a workspace from this template and choose CPU, memory, and disk.
+2. Connect via `coder ssh <workspace>` or use VS Code in the browser via the [VS Code extension](https://coder.com/docs/user-guides/workspace-access/vscode).
+3. Install packages declaratively by editing `/etc/nixos/coder.nix` and running `sudo nixos-rebuild switch`.
+
+## Notes
+
+- `code-server` is not installed by this template. The Coder agent is started as a plain systemd service. Install editors via nix packages in `coder.nix`.
+- The first workspace start takes several minutes while `nixos-rebuild switch` runs. Subsequent starts are fast.
+- Advanced Incus remotes (targeting a separate host over the network) are not supported by this template. See the `incus-vm` template for guidance on adding remote support.
