All,
Here is the first draft:
https://wiki.fd.io/view/CSIT/vhostuser_test_scenarios
I did my best to capture all inputs as per this thread. But it’s hardly
readable yet - requires more TLC :)
See what you think - feel free to add/edit things directly on
FD.io<http://fd.io> wiki page.
Suggest to discuss next steps on csit weekly call tomorrow, details here:

All,
At last week's CSIT meeting, Maciek
(mkons...@cisco.com<mailto:mkons...@cisco.com>) offered to compile a summary
suggestions on this mailing list.

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.

All:
Soliciting opinions from people as to vhost-user testing scenarios and guest
modes in fd.io<http://fd.io/> CSIT testing of VPP - vhost-user.
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
