Tutorial: install and configure NixOS for nix-bitcoin on VirtualBox (macOS host)
---
## 1. VirtualBox installation (macOS)
The following steps are meant to be run on the machine you deploy from, not the machine you deploy to.
1. Download and install VirtualBox
Use the official Downloads page: [https://www.virtualbox.org/wiki/Downloads](https://www.virtualbox.org/wiki/Downloads)
Make sure that the installer you download shows a lock icon in the top right corner to make sure it is signed by Oracle.
2. Create Host Adapter in VirtualBox
```
vboxmanage hostonlyif create
```
## 2. Nix installation (macOS)
Follow the instructions from [Nix installation on debian](#2-nix-installation). You will may need to replace `gpg2` with `gpg`.
## 3. LinuxKit Nix installation
In order to build binaries for your linux (NixOS) virtual machine on a macOS host machine, you need to use [linuxkit-nix](https://github.com/nix-community/linuxkit-nix). It uses hyperkit to spin up a separate VM on which it builds binaries. An alternative solution is [nix-docker-build-slave](https://github.com/LnL7/nix-docker/blob/master/start-docker-nix-build-slave).
1. Installation
```
nix-env -i /nix/store/jgq3savsyyrpsxvjlrz41nx09z7r0lch-linuxkit-builder
nix-linuxkit-configure
```
You may want to use `nix-linuxkit-configure -c 4` to give the builder 4 CPUs.
2. Confirm that nix-linuxkit works
```
nix-build /Users/lev/.cache/nix-linuxkit-builder/example.nix
```
As the installer says, run a `nix-build` to make sure that you are able to build linux binaries. The `example.nix` is specifically configured to force a x86_64-linux build. Remove the generated `result` folder afterwards.
## 4. Nixops deployment (macOS)
Follow the instructions from [Nixops deployment on debian](#3-nixops-deployment). Add `--option system x86_64-linux` to the `nixops deploy` command in step 5 to force your system to use linuxkit-nix.
