Darwinix is a flake designed for quickly spawning VMs on aarch64-darwin systems.
Currently, Darwinix supports creating a NixOS VM. You can spawn a NixOS VM using the following command:
nix run "github:matteo-pacini/darwinix#nixos"
This command will create the necessary VM files locally if they are not found (e.g., EFI, EFI varstore, disk, etc.) and then start the VM.
Futher arguments passed to the command invocation are sent to qemu-system-aarch64 directly, i.e.:
nix run "github:matteo-pacini/darwinix#nixos" -- -cdrom "/path/to/image.iso"
All VMS come with Internet and a CoreAudio-bound audio device. Copy-paste between host and guest is also supported.
QEMU needs to be compiled for the first run for this to work, as a few macOS 11.0+ functionalities are currently disabled in the official derivation.
RAM and CORES environment variables can be used to override the launch script defaults (half of the CPU cores, +1 if result is odd, and 1/4th of the available RAM.).
Example:
CORES=2 RAM=4 nix run "github:matteo-pacini/darwinix#nixos"
