Uhm, apart from the fact that the page clearly states this is a "hack", 
so it's far from being a best practice (although surely easy and 
interesting!), AFAICT this might help with adding rules to the NAT 
table, which was the first part of my question, but does not help with 
the network restart issue because hook scripts are only called upon 
libvirt events: libvirt daemon start/stop, guest start/stop...

Did I understand correctly?

Indeed, looks like this would be overkill for my needs.

Thank you!
