SmartNIC DPU Enablement in OpenStack with OVN
summary
OpenStack and OVN patches move OVN/OVS control plane onto DPU hosts using PCIe VPD discovery in Nova, Neutron binding and devlink representative‑port lookup; demo uses NVIDIA BlueField-2 with ConnectX6 offload and shows an accelerated instance scheduled to the DPU host, VF attached and flows programmed into silicon (visible as flows offloaded). Implementation changes Nova, Neutron, OVN and Libvirt, uses standard PCI/devlink interfaces and lands in OVN 22.03 / Open vSwitch yoga — the end-to-end demo works.
