  Follow, if possible guide, but keep backward compatibility :-)

  The only risk I see right now, is about the XML format, I raised the
point here in Ottawa (OLS) and the answer texto was 
  "we don't see why libvirt XML format should be different from Xen one"
my own biased viewpoint is that I don't see why Xen upcoming XML format
should be different from libvirt one, but there is some hopes :-)

  I raised the issue publicly, got the previous answer, I'm afraid they
didn't look at it yet, and could not get any technical answer at this 
point, but we have a statement to this effect. The best you can do
is also give feedback to the Xen guys to this intent :-)
