I'm afraid there's no easy way to trigger events on network create or
delete directly via libvirt at this time. 

One possible alternative you could try is to use udev. I see udevadm
triggers events ...

KERNEL[1263327559.060277] remove   /devices/virtual/net/virbr0 (net)
UDEV  [1263327559.107126] remove   /devices/virtual/net/virbr0 (net)
KERNEL[1263327570.179500] add      /devices/virtual/net/virbr0 (net)
UDEV  [1263327570.219653] add      /devices/virtual/net/virbr0 (net)
