I gave this a try on my M3 MBP and seems to work well! I took the default flake template and tweaked slightly: {
description = "NixOS in MicroVMs";
nixConfig = {
extra-substituters = ["https://microvm.cachix.org"];
extra-trusted-public-keys = ["microvm.cachix.org-1:oXnBc6hRE3eX5rSYdRyMYXnfzcCxC7yKPTbZXALsqys="];
};
inputs.microvm = {
url = "github:microvm-nix/microvm.nix/pull/397/head";
inputs.nixpkgs.follows = "nixpkgs";
};
outputs = {
self,
nixpkgs,
microvm,
}: let
system = "aarch64-darwin"; # <-- switched to Darwin
in {
packages.${system} = {
default = self.packages.${system}.my-microvm;
my-microvm = self.nixosConfigurations.my-microvm.config.microvm.declaredRunner;
};
nixosConfigurations = {
my-microvm = nixpkgs.lib.nixosSystem {
system = "aarch64-linux"; # <-- explicitly set
modules = [
microvm.nixosModules.microvm
{
networking.hostName = "my-microvm";
users.users.root.password = "";
microvm = {
vmHostPackages = nixpkgs.legacyPackages.aarch64-darwin.pkgs; # <-- added as per the PR
volumes = [
{
mountPoint = "/var";
image = "var.img";
size = 256;
}
];
shares = [
{
# use proto = "virtiofs" for MicroVMs that are started by systemd
proto = "9p";
tag = "ro-store";
# a host's /nix/store will be picked up so that no
# squashfs/erofs will be built for it.
source = "/nix/store";
mountPoint = "/nix/.ro-store";
}
];
# "qemu" has 9p built-in!
hypervisor = "qemu";
socket = "control.socket";
};
}
];
};
};
};
}Running Full output:Building from a different configuration via the nix-darwin linux builder also works as expected: Flake:{
inputs = {
nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
microvm = {
url = "github:microvm-nix/microvm.nix/pull/397/head";
inputs.nixpkgs.follows = "nixpkgs";
};
};
outputs = inputs: {
nixosConfigurations.vm = inputs.nixpkgs.lib.nixosSystem {
system = "aarch64-linux";
modules = [
inputs.microvm.nixosModules.microvm
{
networking.hostName = "vm";
users.users.root.password = "";
microvm = {
hypervisor = "qemu";
socket = "control.socket";
vmHostPackages = inputs.nixpkgs.legacyPackages.aarch64-darwin.pkgs;
mem = 1024;
vcpu = 1;
shares = [
{
proto = "9p";
tag = "ro-store";
source = "/nix/store";
mountPoint = "/nix/.ro-store";
}
];
};
system.stateVersion = "25.11";
services.getty.autologinUser = "root";
}
];
};
};
}Full output:EDIT TO ADD: This also works as expected using nixbuild.net as a remote builder. |

Almost 1:1 copy of #373 with very minor changes, seems to work as expected :)
