In fact I'm not even sure how this helps solve the quoted problem of
detecting libvirtd restarts.

 1. virt-viewer has a connection to libvirtd PID 123
 2. virt-viewer listens for events from libvirtd PID 123
 2. libvirtd PID 123 stops
 3. libvirtd PID 456 starts
 4. libvirtd PID 456 emits started events for virNetwork

How exactly is virt-viewer supposed to be able to use the
virNetwork events to detect libvirtd restarts ? They are
being  emitted by a libvirtd daemon that virt-viewer is
not even connected to.

Regards,
Daniel
