Apple Virtualization NixOS ISO

Run NixOS ISO using Apple Virtualization framework (for example UTM)

  • local: Download ISO
    • 22.05 or build ISO: nix-build -A iso_minimal.aarch64-linux '<nixpkgs/nixos/release.nix>'
    • 22.11 Minimal 64-bit ARM
  • local: Mount hdiutil mount *.iso
  • local: Copy kernel and initrd: cp /Volumes/nixos-minimal-2?/boot/{Image,initrd} ..
  • local: Find and copy kernel params: less /Volumes/nixos-minimal-2?/EFI/boot/grub.cfg
  • local: Append console=hvc0 to params.
  • UTM: Create a new "drive". 16 GB is comfortable, 64 GB is plenty. Attach to your VM.
  • UTM: Attach the ISO.
