Hi,
During the Kilo summit, the folks in the pci passthrough and SR-IOV groups
discussed what we’d like to achieve in this cycle, and the result was
documented in this Etherpad:
https://etherpad.openstack.org/p/kilo_sriov_pci_passthrough
To get the work going, we’ve submitted a few design specs:
Nova: Live migration with macvtap SR-IOV
https://blueprints.launchpad.net/nova/+spec/sriov-live-migration
Nova: sriov interface attach/detach
https://blueprints.launchpad.net/nova/+spec/sriov-interface-attach-detach
Nova: Api specify vnic_type
https://blueprints.launchpad.net/neutron/+spec/api-specify-vnic-type
Neutron-Network settings support for vnic-type
https://blueprints.launchpad.net/neutron/+spec/network-settings-support-vnic-type
Nova: SRIOV scheduling with stateless offloads
https://blueprints.launchpad.net/nova/+spec/sriov-sched-with-stateless-offloads
Now that the specs deadline is approaching, I’d like to bring them up in here
for exception considerations. A lot of works have been put into them. And we’d
like to see them get through for Kilo.
Regarding CI for PCI passthrough and SR-IOV, see the attached thread.
thanks,
Robert

Hi Steve,
Regarding SR-IOV testing, at Mellanox we have CI job running on bare metal
node with Mellanox SR-IOV NIC. This job is reporting on neutron patches.
Currently API tests are executed.
The contact person for SRIOV CI job is listed at driverlog:
https://github.com/stackforge/driverlog/blob/master/etc/default_data.json#L
1439
The following items are in progress:
- SR-IOV functional testing
- Reporting CI job on nova patches
- Multi-node setup
It worth to mention that we want to start the collaboration on SR-IOV
testing effort as part of the pci pass-through subteam activity.
Please join the weekly meeting if you want to collaborate or have some
inputs: https://wiki.openstack.org/wiki/Meetings/Passthrough
BR,
Irena

Subject: [Nova][Neutron][NFV][Third-party] CI for NUMA, SR-IOV, and other
features that can't be tested on current infra.
Hi all,
We had some discussions last week - particularly in the Nova NFV design
session [1] - on the subject of ensuring that telecommunications and
NFV-related functionality has adequate continuous integration testing. In
particular the focus here is on functionality that can't easily be tested on
the public clouds that back the gate, including:
- NUMA (vCPU pinning, vCPU layout, vRAM layout, huge pages, I/O device
locality)
- SR-IOV with Intel, Cisco, and Mellanox devices (possibly others)
In each case we need to confirm where we are at, and the plan going
forward, with regards to having:
1) Hardware to run the CI on.
2) Tests that actively exercise the functionality (if not already in
existence).
3) Point person for each setup to maintain it and report into the
third-party meeting [2].
4) Getting the jobs operational and reporting [3][4][5][6].
In the Nova session we discussed a goal of having the hardware by K-1 (Dec
18) and having it reporting at least periodically by K-2 (Feb 5). I'm not
sure if similar discussions occurred on the Neutron side of the design
summit.
SR-IOV
======
Adrian and Irena mentioned they were already in the process of getting up
to speed with third party CI for their respective SR-IOV configurations.
Robert are you attempting similar with regards to Cisco devices? What is the
status of each of these efforts versus the four items I lifted above and
what do you need assistance with?
NUMA
====
We still need to identify some hardware to run third party CI for the
NUMA-related work, and no doubt other things that will come up. It's
expected that this will be an interim solution until OPNFV resources can be
used (note cdub jokingly replied 1-2 years when asked for a "rough" estimate
- I mention this because based on a later discussion some people took this
as a serious estimate).
Ian did you have any luck kicking this off? Russell and I are also
endeavouring to see what we can do on our side w.r.t. this short term
approach - in particular if you find hardware we still need to find an owner
to actually setup and manage it as discussed.
In theory to get started we need a physical multi-socket box and a virtual
machine somewhere on the same network to handle job control etc. I believe
the tests themselves can be run in VMs (just not those exposed by existing
public clouds) assuming a recent Libvirt and an appropriately crafted
Libvirt XML that ensures the VM gets a multi-socket topology etc. (we can
assist with this).
Thanks,
Steve
