This may not help any but I have run into similar issues whenever I run 
certain services on dom0. Running the same service from a domu and working in 
reverse has always worked.

It all started for me when I noticed my dom0 couldn't see broadcast packets 
and therefore wouldn't respond to broadcast queries. I didn't bother going any 
further and the interest was limited.

I didn't like moving these services to a domu as they were central but 
admittedly it has helped prevent the dom0 from panicing as regularly ;)
