Hi Pat, Thanks for educating me about VDP. Based on what you wrote, it sounds like it might indeed by useful for the VM attach/detach protocol. One concern is that you seem to say the VSI ID can be one of a list of things you mention that sound promising, but can it support multiple of these? For example, the encap/decap device may want to know a Virtual Network's UUID and the VM's MAC and the VM's IP.
