Hardware Accelerated Virtio Networking for NFV - Varun Sethi & Yashpal Dutta, Freescale

Network function virtualization (NFV) leverages standard IT virtualization to consolidate multiple network functions on to a standard platform.The network functions are essentially decoupled from specialized hardware appliances, allowing them to run purely in software, as virtual machines. Network I/O with in the virtual machine becomes extremely critical, especially where network functions handle high traffic rate.
Virtio networking offers a flexible mechanism for sharing I/O interface among virtual machines (also suitable for VM migration). Despite the flexibility, there are performance challenges with virtio (even Vhost-net) for virtual network functions.
In this presentation we discuss the performance issues encountered and how these were mitigated with hardware offloads while running IP forwarding as a virtual network function under KVM hypervisor with Vhost-net networking.
