FD.io Mini Summit - Towards a Single Virtualized Data Path for VPP: Vhost Deep Dive and Analysis - Zhihong Wang

Sign up or log in to save this to your schedule and see who's attending!

There're 2 vhost implementations in VPP currently: vhost-dpdk and vhost-vpp. This situation leads to a convergence path to achieve the best data path between host and guest.
A careful analysis has been done to compare the feature sets and performance of the 2. Also there're great efforts going on to enhance the integration of vhost-dpdk to VPP, because currently it rewrites most functions instead of calling those functions from vhost-dpdk, therefore changes in vhost-dpdk won't go directly into VPP, and the extra integration overhead is seen in VPP.

This session delivers a full comparison between vhost-dpdk and vhost-vpp, and updates the recent efforts in vhost-dpdk development and VPP integration. We propose vhost-dpdk as the single vhost for VPP, because it provides better performance and richer function support. More importantly, this aligns well with DPDK and FD.io integration mode.
