Migrating our workflow to macOS, you could have a NixOS configuration defined The first issue that needed to be fixed is the lack of a simple interface forīuilding and running NixOS VMs on macOS. Linux host, multiple changes to the status quo are needed to make itĬomfortable to work on them on macOS, presented in the following sections. Since the conventional means of working on NixOS configurations relies on a Same mechanism as other NixOS VMs, so it doesn’t work on macOS out of the boxĮither. Them, interact with them and check their state. You just provide it with a piece of NixOSĬonfiguration for all machines that you need and it provides a neat API to run NixOS provides a powerful framework for testing different nixos-rebuild by default makes theĪssumption that the local machine is Linux and links to Linux Bash and QEMUīinaries, so you can’t run it locally. However, on macOS none of that will work. Virtualisation.vmVariant that imports the virtualisation/qemu-vm.nix module It uses a NixOS configuration variant from It to run as a daemon on your host by using the attribute ofĪny NixOS configuration. You can even rely on it to wrap some services into a VM and configure Into the VM and boots the VM straight from it, with no additional image It is very lightweight because it mounts your /nix/store directory directly You to verify if the configuration works without affecting any actual system. To generate a script that will start a local QEMU virtual machine. When you are running Linux locally, you can easily run nixos-rebuild build-vm You might want to start deploying NixOS to remote machines. Now that you can build and run packages for your target Linux system, As for linuxkit-nix,īlog post a great overview of how it is lacking inĭifferent areas.
#MACOS LINUX VIRTUAL MACHINE INSTALL#
Most of these options require you to install some app that will manage VMs for It in Docker’s VM or linuxkit-nix to spawn a minimal Linux VM VirtualBox, UTM, Parallels or vmWare, or using nix-docker to run
Opt for the latter, reaching for either running a complete Linux VM in If you have a powerful enough machine, you might want to Some other machine (in the cloud, some datacenter, or under your desk), or in a
Therefore, you have to set up a remote builder, either on Practically speaking, this means thatĪ derivation for any of them requires a Linux machine with Nix to be Machine, be it to a remote server, VM or container, you most likely end up in
MacOS is a great desktop environment, but as soon as you move beyond your I’llĭescribe some major use cases for it below. That are used for developing and testing it require running it in VMs. However NixOS is based on Linux and so many pieces Like many members of the Nix community – more than 25% according to the NixĬommunity survey – I rely on macOS to provide me a stable To make it easier for myself (and others). My first minor achievement in this area, and it struck me that I have neverĭescribed why exactly I run virtual machines (VMs) on my laptop and why I want
My colleague at Tweag, Dominic Steinitz, asked me this question after I shared Why would I want to run a NixOS virtual machine on macOS? MacOS and how we can make this task easier. In this post I want to explore the current issues with developing parts of NixOS on
