Based on start/shutdown of the host or starting/stopping libvirtd. I
just wrote a script to start with systemd but as there is that autostart
functionality in libvirtd this might not be the best solution.

networks with autostart set will be started when libvirtd is started if 
they are seen to be inactive, but they will never be stopped by libvirt. 
libvirtd is designed so that it can be restarted at any time without 
disrupting any active guest or network, and doing an auto-shutdown of 
the network would go against that.

Also, when using libvirt's hook scripts, you need to keep in mind that 
the scripts cannot call back into libvirt (e.g. using virsh) as that 
would create a deadlock.

None of that really answers your question, but hopefully it at least 
gives you a better idea of what you've got to work with :-)

You are right ;) I guess making my initialization hook fault-tolerant
towards missing cleanup plus the systemd script should fit for me.
