Not a peep in there.  Not even a there, there.

 xl create test.cfg

 ls -al /var/log/xen/xen-hotplug
  ls: cannot access /var/log/xen/xen-hotplug: No such file or directory

I haven't made any local modifications.  At least not intentionally.

Here's the vif-bridge script ==> http://pastebin.com/9nHESsqS

It's opensuse.

I already have.  Well, I tried.  Both on their mailing list
(opensuse-virtual), and cc'ing this thread to one of their developers
seemingly active on this mailing list.

So far the only reponses have been - there - from someone on Fedora16
seeing the same problem, and - here - from non-suse types, such as
yourself, trying to help.  Other than asking for their help, I don't
know how to convince them to help.  I can only work with the assistance
of folks that'll talk to me about the problem.

I don't understand the question.  Is there some specific detail I can
give you ?  Is it the value of 'domu' you're after?

Does the script pastebin above answer that for you?
