I appreciate the feedback.

I read about that on libvirt.org but chose not to make any changes 
since the Xen server already works with the same config I have on the 
KVM server.  I understood libvirt to be a layer that lets one compatible 
tool work with many different hypervisors, so I didn't think I'd need to 
change my libvirt config to work with KVM if it already works with Xen. 
  That might be a bad assumption, though, and I'm not wedded to it.  :)

I did that and will take the discussion there.

Thanks,
