That is normal in newer Xen setup. veth are not created. vifs are only
created when there's a domU running. This is different from older Xen
setup, where it would create vif-veth pair in dom0.

  hmm, yep I see that in 3.4.2 veth and vif were created by default but in xen 4.0 I dont see veth and/or vif  being created.

Is there any documentation for above or related in Xen 4.0 ?

I'm guessing you don't have network backend support built on dom0.
Which dom0 kernel did you use? How did you build it?
   I build and package it myself. dom0: 2.6.32-13 kernel.   How do I enable the backend support ?
