Overlay tunneling provides isolation without using VLANs, and allows VMs to communicate at L2 even when the computes nodes they are on are not on the same physical L2 network. In the Folsom release of Quantum, both the OVS plugin and Nicira NVP plugin include support for this type of overlay tunneling. Dan > > Suggestions?
