NO_SUPPORT isn't really the best error code to use here - that's intended
for public API calls which aren't implemented by a driver. 

Our reporting of XML configurations which aren't valid is pretty rubbish
as we don't have a standard error code - people have been making it up as
we go along.

I think we should add a new error code:

  VIR_ERR_CONFIG_UNSUPPORTED

whcih we can then standardize on for this kind of thing

Regards,
Daniel
