DV: sorry, wrong webclient.

DP: Would a patch be accepted that makes this configurable for *all*
implementations? So that by after configuration a file is saved, and is
queried after the platform specific implementation doesn't list the 
domain as defined?

List Defined domains:
  - Query current implementation
  - If defined merge all non available domains.

In principle what I want to see is that if a domain is not defined in 
the specific hypervisor, the domain file can be queried. I know I can 
implement this behavior in my own code, but I really thing this would be 
a cool thing for more people.
