Thank you both for your contributions!

If a bug is found and fixed in extnet,
http://www.ovirt.org/VDSM-Hooks/network-nat would have to be updated as
well.

It would be more elegant to ship an additional script with an independent
custom property, say "ovs_portgroup". This script would run after extnet
does, and would add the portgroup attribute to to the proper element.

Who's posting this to gerrit first?
