Adding: this is about gnunet-service, previously not published. I can't
continue with git service due to the reasons you will see in the
reminder I've sent about it in the thread.

Do I have to add a networking bridge in GuixSD for the VM to work?
Currently nscd in the VM is discovered at 10.0.2.2 and the VM gets
10.0.2.15. If so, can you either point me to documentation or what I
have to search for or provide some quick instructions how I set this up
on GuixSD?
