Created attachment 1239009 [details] Neutron managed OVS-DPDK networking Description of problem: NFV System hardware reference architecture has two pairs of NIC ports. 1 pair is dedicated for Mgmt, storage and pxe traffic. And, other pair is dedicated for guest VM traffic (both tenant traffic and fip traffic). We do want to allows VNF workload use either tenants network types - VxLAN network or provider VLANs. Secondly, we don't have additional NICs to configure External Network on separate interface. Both neutron and ODL managed networking needs this mixed tenant network type support over OVS-DPDK networking. The diagram illustrated in the attachment gives finer details or use case Additional info: See the attachment.

We can also use Linux bonding interfaces for the management interfaces, shared with the compute node OpenStack API services, and dedicate the other interfaces to OVS-DPDK.
