I totally agree that configuring the network directly on the hosts
should be avoided.

I think I misunderstood the issue of Rickard - I thought he has issues
configuring network for the engine itself. 
But (after reading your last email with your suggestions) the question
is how to define logical networks in engine and deploy config on hosts
(if this is the case please don't do any configuration manually with an
editor.)
