of course. My proposal is related to our user usage of the system. Today
ovirt user, who wants to define a network subnet, has to type the subnet
per host (per network), I think the user should only define it once on
the logical network entity in the Data Center.
Propagating the value to all hosts is needed but it should be our
internal implementation detail.

No, hope the above paragraph made it more clear.
