Since libvirt-guests script/service can operate on various URIs and we do support both socket activation and traditional services, the ordering should be specified for all the possible sockets and services.

Also remove the Wants= dependency since do not want to start any service. We cannot know which one libvirt-guests is configured, so we'd have to start all the daemons which would break if unused colliding services are not masked (libvirtd.service in the modular case and all the modular daemon service units in the monolithic scenario). Fortunately we can assume that the system is configured properly to start services/sockets that are of interest to the user. That also works with the setup described in https://libvirt.org/daemons.html .

To make it even more robust we add the daemon service into the machine units created for individual domains as it was missing there.

Surely these two variables need to be swapped.

Otherwise looking good. Michal
