All,
We didn’t have much time to discuss the vhostuser use cases on CSIT
project call earlier today.
On the call we also didn’t have all the interested parties that were
providing feedback to date.
Hence agreed to hold a separate Tech WorkStream call to cover this.
Quick check on #fdio-csit irc, this Friday AM PST seems to work for folks.
What about 08:00-09:00 PST this Friday?
0900-10:00 PST would be better for me.
If yes, I will post meeting details here:

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

All,
At last week's CSIT meeting, Maciek (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
