Hi Folks,

Based on Thursday's discussion and a chat with Irena, I took the liberty to add a summary and discussion points for SRIOV on Monday and onwards. Check it out https://wiki.openstack.org/wiki/Meetings/Passthrough. Please feel free to update it. Let's try to finalize it next week. The goal is to determine the BPs that need to get approved, and to start coding.

Sounds great! Let's do it on Thursday.

Hi Robert, all,
I would suggest not to delay the SR-IOV discussion to the next week.
Let’s try to cover the SRIOV side and especially the nova-neutron interaction points and interfaces this Thursday.
Once we have the interaction points well defined, we can run parallel patches to cover the full story.

Thanks a lot,

Hi Folks,

As the debate about PCI flavor versus host aggregate goes on, I'd like to move forward with the SRIOV side of things in the same time. I know that tomorrow's IRC will be focusing on the BP review, and it may well continue into Thursday. Therefore, let's start discussing SRIOV side of things on Monday.

Basically, we need to work out the details on:
        -- regardless it's PCI flavor or host aggregate or something else, how to use it to specify a SRIOV port.
        -- new parameters for —nic
        -- new parameters for neutron net-create/neutron port-create
        -- interface between nova and neutron
        -- nova side of work
        -- neutron side of work

We should start coding ASAP.
