In general dom0 doesn't have much insight into the internals of other
guest OSes, which is what you would need in order to be able to match
network sockets to processes.

The Xen Introspection project (AKA xenaccess?) might have some of the
building blocks you need to make something like this work though. I'm
afraid I don't know any more about that project than its existence.

The other alternative would be an in guest daemon which collects and
exports this data, e.g. into xenstore.
