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.

LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
