Comment 2 for bug 1519748

From Kennan in the MailList:
Hi HouMing,
I checked the heat templates again, and check with heat developers.
For heat stack creation now, it can not directly use existed network when create new stack. which means, it need create a new net and subnet.
So for fixed_network, the name is still need. just like when you create network in neutron, you need network and subnet.

I think right now, so for magnum point of view what can be controlled is, 1. network name related properties settting. 2. subnetwork related properties. like CIDR.

So for fixed_network, give it still what role should be.

Add a new fixed_subnet for that.

Of course, this can also be discussed in weekly meeting if needed.
