231. vm2vm vhost-user/virtio-user test plan

231.1. Description

This test plan includes split virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test, and packed virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable path test. This plan also check the payload of packets is accurate. For packed virtqueue test, need using qemu version > 4.2.0.

231.2. Prerequisites

Enable pcap lib in dpdk code and recompile:

--- a/config/common_base
+++ b/config/common_base

 #
 # Compile software PMD backed by PCAP files
 #
