Software Defined Networking in CloudStack
summary
CloudStack ships SDN as pluggable providers (about 8 implementations so far) that create logical switches and ports via controllers (not manual VLANs); initial work uses Nicira NVP with GRE tunnels, later adds VXLAN support and plugins for Big Switch, Midokura and others. Core mechanics use a network offering plus a network guru/element model where the guru asks an SDN API to prepare a network (returns a broadcast URI) and the element wires VM NICs to controller ports. Production use reports it works but feature parity, on‑ramp/off‑ramp and hypervisor integration remain challenges.
