The purpose of this document is to illustrate how to test vhost-user-net
in cloud-hypervisor with OVS/DPDK as the backend. This document was
tested with Open vSwitch v2.13.1, DPDK v19.11.3, and Cloud Hypervisor
v15.0 on Ubuntu 20.04.1 (host kernel v5.4.0).
tested with Open vSwitch v2.17.8, DPDK v21.11.4, and Cloud Hypervisor
v37.0 on Ubuntu 22.04.3 (host kernel v5.15.0).
