Bug Description

OS is Kilo.

A VM assigned multiple interfaces.

After successfully booted. The server_show command result (attached) will show each interface's add, version and mac on the addresses attributes.

However, the security_groups show a list of security_groups being applied to the VM, not which interface.

It is possible to have different security_groups assigned to interface based on the network an interface attached to.

We need to enhance the security_groups, like the addresses field to indicating which interface, the security_groups belong to.

Here is a return from a server-show command:

So this is fun. Nova-network only applies security groups per VM, neutron does it per port.

I think the correct fix is to stop returning the security groups at all, it's basically a neutron proxy, which we are trying to deprecate.

In reality this will be easier once we have finally removed nova-network, as it's currently useful for nova-net people.

Either way, this needs a new microversion and as such needs a spec to approve that change. It's probably going to roll into a remove network proxy API spec.
