Vagrant and Virtualbox fail to run in a systemd unit

Help

I want to autostart a vagrant/virtualbox machine when I access a port on localhost. The vagrant machine is a development environment for web development.

Until now I have

{ pkgs, ... }: {
  virtualisation.virtualbox.host.enable = true;
  users.extraGroups.vboxusers.members = [ "lucc" ];
  environment.systemPackages = [ pkgs.vagrant ];
  systemd.user.sockets.vagrant.listenStreams = [ "8880" ];
  systemd.user.services.vagrant = {
    path = with pkgs; [ vagrant virtualbox curl ];
    script = "vagrant up --provision --no-tty --no-color";
    serviceConfig.WorkingDirectory = "/bla/bla/bla";
  };
}

With the first three lines I can manage the vagrant machine manually from the shell so this is good.

The user socket also correctly triggers the service when I access http://localhost:8880, so I think this is also good.

The problem seems to be the vagrant.service, when I start it it complains that it can not find virtualbox:

...

Dec 17 11:11:25 localhost systemd[1718]: vagrant.service: Main process exited, code=exited, status=1/FAILURE

But when I execute the start script from the systemd unit in my shell it runs jist fine.

How can I make vagrant + virtualbox work in a systemd unit? Or alternatively how can I autostart my vagrant + virtualbox machine on a NixOS system as soon as I access the port localhost:8880?

It is probably related to security wrappers and user groups.

  1. Add /run/wrappers/bin to path
  2. Make sure the user is in the vboxusers group (seems to be already)

With

script = ''
export PATH=/run/wrappers/bin:$PATH
vagrant up --provision --no-tty --no-color
'';

the error is exactly the same.
