<p class="MsoNormal" style="margin-bottom:12.0pt">I've wondered exactly the same question -- or, put another way, why have the concept of a "subnet" at all; why not just have one or more network objects that have either a CIDR or set of IP ranges set on them,
along with certain flags like "shared". The way the API is right now seems needlessly complex.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">IMO, a tenant should be able to create a router for their networking, create one or more networks for their private addresses, configure the router's gateway to speak with the shared "public" network, and be done with it. The sheer number
of steps that is currently necessary to make in order to set up a simple private network for a tenant's VMs is cumbersome and smells of "implementation leaking into the API".<o:p></o:p></p>
