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. > > Network mask is used in any case, I guess it can be dropped from > configuration in favour of using the address class as mask, is > that what you suggest? > No, hope the above paragraph made it more clear.
