# Test VM for the Hallo Nix Flake
To build and start a test VM, in this directory, with a copy of Nix that supports flakes, run:
```shell
nix build .#nixosConfigurations.testvm.config.system.build.vm -j8
./result/bin/run-nixos-vm
```
(An amd64 system is needed for now; otherwise you need to edit `outputs.nix`.)
