This sounds reasonable, but I'm wondering if old XenD support the
lookup-based on name ?
Yes, I had thought about this as well. Guess it depends on how old we
are talking about. It exists in Xen 3.1.x and newer. I wonder if we
should even care about Xen 3.0.x. The upstream tree hasn't been touched
in 3 years.
