  Well, I'm afraid it may be a specific property of the interface to xend
used, I honnestly don't know why this worked, this wasn't expected.
  I would not rely on it, and also depending on the available interfaces
virDomainLookupByName and virDomainLookupByID could be really expensive
or really cheap, they don't have the same properties, also IDs can change
for example if you do save and restore operations of a domain.
