What does the log say about? (e.g. xend.log, xend-debug.log,
domain-builder-ng.log)

Can you identify the network scripts? If so you may better debug them
by putting this three sentences before anything gets executed:

#!/bin/bash
## Some comment...
exec 3> /var/log/temporal.log
export BASH_XTRACEFD=3
set -x

If the scripts are bash scripts, that will log every command executed
to the specified log file, and we will be able to trace each
networking command executed and better debug the problem.
