Thanks Somik, One question: in the "Quantum-Dashboard workflow today", what determines how many vNICs a VM is given?
In general, I see a couple key areas for improvement in the network workflow: - Be able to use the Dashboard to create a network with a specified subnet. Under the covers, this would create the Quantum network, and a Melange subnet. - When creating a VM, you should be able to specify the # of VIFs for that VM. Each VIF could optionally specify a quantum network to be connected to and a Melange subnet to get an IP from. This provides the flexibility to make interesting network topologies, because you no longer have the requirement that every VM for a project is connected to the same set of networks. This flow is similar to what I prototyped with the "simple quantum orchestrator" here: http://wiki.openstack.org/QuantumOVSDemo One interesting point to discuss is whether L2 networks and subnets should be tightly coupled in a GUI or not. I can certainly think of cases where you might not want them to be coupled, but in the common case they are.
