Generally, I agree with you. But it's a little tricky.
There are different types of SR-IOV NICs and what will work for some vendor may be broken for another.
I think that both current SR-IOV networking flavors: Embedded switching (Intel, Mellanox) and Cisco VM-FEX should be verified for relevant nova patches.
What tests do you think it should run for nova side?

Thanks,
Irena

Hi,
If I understand correctly the only way that this work is with nova and neutron running. My understanding would be to have the CI running with this as the configuration. I just think that this should be a prerequisite similar to having validations of virtualization drivers.
Does that make sense?
Thanks
Gary

Hi Gary,
I understand your concern. I think CI is mandatory to ensure that code is not broken. While unit tests provide great value, it may end up with the code that does not work...
I am not sure how this code can be checked for validity without running the neutron part.
Probably our CI job should be triggered by nova changes in the PCI area.
What do you suggest?

Thanks, the concern is for the code in Nova and not in Neutron. That is, there is quite a lot of PCI code being added and no way of knowing that it actually works (unless we trust the developers working on it :)).
Thanks

Hi Gary,
Mellanox already established CI support on Mellanox SR-IOV NICs, as one of the jobs of Mellanox External Testing CI (Check-MLNX-Neutron-ML2-Sriov-driver<https://urldefense.proofpoint.com/v1/url?u=http://144.76.193.39/ci-artifacts/94888/13/Check-MLNX-Neutron-ML2-Sriov-driver&k=oIvRg1%2BdGAgOoM1BIlLLqw%3D%3D%0A&r=eH0pxTUZo8NPZyF6hgoMQu%2BfDtysg45MkPhCZFxPEq8%3D%0A&m=OFhjKT9ipKmAmkiQpq6hlqZIHthaGP7q1PTygNW2RXs%3D%0A&s=13fdee114a421eeed33edf26a639f8450df6efa361ba912c41694ff75292e789>).
Meanwhile not voting, but will be soon.

BR,
Irena

Gary,

Cisco is adding it in our CI testbed. I guess that mlnx is doing the same for their MD as well.

Hi,
At the moment all of the drivers are required CI support. Are there any plans regarding the PIC support. I understand that this is something that requires specific hardware. Are there any plans to add this?
Thanks
Gary
