Re: [libvirt] [PATCH 3/3] virNetServerRun: Notify systemd that we're accepting clients

Systemd does not forget about the cases, where client service needs to wait for daemon service to initialize and start accepting new clients. Setting a dependency in client is not enough as systemd doesn't know when the daemon has initialized itself and started accepting new clients. However, it offers a mechanism to solve this. The daemon needs to call a special systemd function by which the daemon tells "I'm ready to accept new clients". This is exactly what we need with libvirtd-guests (client) and libvirtd (daemon). So now, with this change, libvirt-guests.service is invoked not any sooner than libvirtd.service calls the systemd notify function.
