Hello Thomas, Sorry I haven't reached out faster, I was travelling.
Please have a look at vppsb/vhost-test It includes a standalone script which provides VPP and VM configuration for PVP tests. - Runs testpmd in the VM - Supports various CPU configuration for VPP - Can run with or without gdb, debug or release Not committed yet: - Supports VM restart - Support for VPP restart - Support for multiple additional (dead) vhost interface I did that outside of the context of CSIT so people can: - Look at it and see what are the optimisations that are used - Use it without CSIT I will keep using and improving it because I use it for my own development and testing purposes. Rest of this inline.

I will forward to this mailing list as well as summarize any additional feedback. I asked some people that happen to be here at OVSCON as well as some Red Hat and Intel people. I am also including some people that are involved in upstream vhost-user work in DPDK. So far, I have the following feedback with an attempt to condense feedback and to keep the list small. If I left out anything, let me know. In addition to the PVP tests done now with small packets. Testpmd in guest is OK for now. 1 Add multiple VMs (How many?) Makes sense to me. 2 is enough (4 would be good number). 2 Both multi-queue and single-queue Yes. Ideally, 1-2-4 queues. With different number of workers (0 workers, i.e. single VPP thread, 1 worker, queues*2 workers). 3 Tests that cause the equivalent of multiple flows in OVS. Varying variety of traffic including layer 2 and layer 3 traffic. Yes. Should test with L2 and L3. 4 Multiple IF's (Guest or Host or Both?) Possibly. But more importantly, I think, we need to have VM restart and interface restart (delete - create). OpenStack integration generates a significant amount of delete-recreate of vhost interface. The following might not be doable by 17.01 and if not consider the following as a wish list for future: 1 vxLan tunneled traffic 2 VPP in guest with layer 2 and layer 3 vRouted traffic. 3 Additional Overlay/Underlay: MPLS --TFH -- Thomas F Herbert SDN Group Office of Technology Red Hat _______________________________________________ vpp-dev mailing list vpp-dev@lists.fd.io<mailto:vpp-dev@lists.fd.io> https://lists.fd.io/mailman/listinfo/vpp-dev
