Integration test is done with a NixOS VM that is created with:

```bash nixos-rebuild build-vm --flake .#testvm

QEMU_OPTS="-netdev bridge,id=hn0,br=intern -device e1000,netdev=hn0" ./result/bin/run-i2s-test-vm ```

The QEMU_OPTS depend on your system, in this example, the VM is attached to local bridge intern.
