Comment 2 for bug 1046358

Yes, this should work.

We actually intentionally did not implement this in the code, as we have another model for doing the same thing: rather than telling nova all of the network config you want, you create a quantum port with a particular config (e.g., IP address, etc.), and then pass that port in when booting a VM using --nic port=id=XYZ. The goal here is that we didn't want the set of options that you pass to --nic to explode to include everything that quantum will support in the future. That would be a mess for the nova folks.

Given that nova already supported to the v4-fixed-ip flag pre-quantum, there's a reasonable argument that we should try and support that flag just for backward compat.
