Let me rephrase that to be more explicit. Certain organizations, for various reasons, require people in the process chain to actually make dns changes... No amount of automation can easily address that issue. Hopefully that can change in time. But stuff as simple as letting users launch vm's can be a hard enough enough sell, without requiring automated access to change dns.

That being said, thats a cool patch. I wish I could use it. :) Hopefully some day.

Thanks,
Kevin

We also have work going on now to automate the addition and update of
DNS entries as VMs come and go [1].  Please have a look and provide
feedback.
