This article walks you through configuration of OVS with DPDK for inter-VM application use cases. Create an OVS vSwitch bridge with two DPDK vhost-user ports, each connected to a separate VM, then use a simple iperf3 throughput test to evaluate performance.
The networking world is rife with buzz words like SDN, NFVs, Cloud, and Virtualized everything for network switches, routers, firewalls, load balancers, web servers, and other communication functions. Commodity NICs can replace expensive, specialized hardware devices for much less cost and can easily be reconfigured as requirements change. When you are ready for SDN/NFV, where to start, what to...
SRIOV mode allows partitioning of SR-IOV capability on Ethernet NIC resources logically, and expose them to a virtual machine as a separate PCI function called a “Virtual Function”.
SR-IOV enables configuration of a single physical network port to provide virtual functions (VFs) to a set of virtual machines (VMs). Learn how to configure SR-IOV by following the steps in this article.
