Only one listed. What is more odd is that I am not seeing arps being returned so this issue seems to be at layer 2. Any other ideas?

I can get quantum to assign the second IP address to the instance but when trying to do anything to that second IP, traffic is blocked by something. I have verified that iptables is updated on the hypervisor and I can see flows in OVS inbound but no replies. I can even see the traffic making it to the instance as well via tcpdump and also see the replies going out for the initial ARP as well from inside the instance. The ARP never seems to make it into OVS as a flow. Is Quantum missing a configuration for a flow somewhere or is there something more I should look for? Does it work for anyone else or did I hit a bug?

It shows up in quantum port-list as well as quantum net-list and is able to route traffic in and out of my vlan'd network. I have a requirement to assign another fixed IP (not floating) from a new vlan to the same virtual interface on the instance. When I create another subnet in quantum, that works. How do I assign an ip address from the new subnet to the same openvswitch port via quantum?
