During the summit session on the the VMWare driver roadmap, a topic of
validating the passed configuration prior to starting services came up
(see  for more detail on how it's connected to that specific topic).
Several ideas were thrown around during the session mostly documented in
There are a few more cases when something like this could be useful (see
bug  and related patch ), and I was wondering if a slightly
different approach might be useful. For example use an already existing
validation hook in the service class  to call into a validation
framework that will potentially stop the service with proper
logging/notifications. The obvious benefit would be that there is no
pre-run required from the user, and the danger of running a
misconfigured stack is smaller.
Since there is already a blueprint raised based on the etherpad - I
am bringing this up here so that we can agree on the approach, before
raising another one to solve the same problem.
