| lakerzhou2 | hongbin, can zun create container by specifying a neutron port instead of network-id via kuryr? | 17:37 |
| lakerzhou2 | hongbin, currently nova only support creating VM with SR-IOV port, which was created already. Networkid is not good enough here, because VM-1 can connect to Nework-N (VLAN) via regular binding using libvirt, VM-2 can connect to the same network-N via direct binding (SR-IOV) even on the same host | 17:41 |
| hongbin | lakerzhou2: i think that is a good idea | 17:44 |
| hongbin | lakerzhou2: this feature sounds like part of the network-api BP: https://blueprints.launchpad.net/zun/+spec/network-rest-api , mkrai , see the requirement above | 17:46 |
| hongbin | lakerzhou2: what is the API sound look like from your perspective ? | 17:55 |
| lakerzhou2 | hongbin, give me a few minutes please, i will get back to you | 17:56 |
| hongbin | lakerzhou2: sure, i need to go out to get a coffee as well | 17:56 |

| lakerzhou2 | hongbin, nova boot vm1 --nic port_id=$port_id ... For zun, we should support 1) multiple endpoints; 2)attaching adding endpoints. I read somewhere docker container can only connect to one network at creation time, but container can attach to multiple network after creation | 18:12 |
| lakerzhou2 | *attaching additional endpoints* | 18:12 |
| lakerzhou2 | Hongbin, the question is what kuryr can support. The document (maybe out dated) saying kuryr listens to /NetworkDriver.CreateEndpoint then will fetch port from neutron to match endpoint options (CIDR). | 18:19 |
| lakerzhou2 | Hongbin, In SRIOV case, we should add a new endpoint option (e.g. PciPassthrough=direct for example). | 18:25 |
| lakerzhou2 | Hongbin, Kuryr will have to bind the port according to its endpoint option - for SR-IOV port, default veth pair binding is not good | 18:26 |
| hongbin | lakerzhou2: i see | 18:26 |
| hongbin | lakerzhou2: for the nic option and the dynamic attaching endpoints, i think those are good ideas | 18:28 |
| hongbin | actually, i will write it down to the whiteboard of the BP | 18:28 |
| hongbin | lakerzhou2: another problem is how to specify a neutron port when creating the container? | 18:29 |
| hongbin | lakerzhou2: the last problem is how to do the neutron port binding i guess | 18:30 |
| lakerzhou2 | hongbin, I am trying to document all of these thoughts in spec. I am thinking to specify network as we do today, then add additional endpoint options. | 18:31 |
| hongbin | lakerzhou2: yes, then kuryr has to understand that endpoint options i guess | 18:32 |
| lakerzhou2 | hongbin, there are kuryr dependency for sure if we use kuryr driver. But most challenge part for me is neutron port binding. | 18:33 |
| hongbin | lakerzhou2: kuryr is designed to be pluggable for port binding AFAIK | 18:34 |
| lakerzhou2 | Hongbin, network creation, SR-IOV port creation are out-of the scope of kuryr and Zun | 18:34 |
| hongbin | lakerzhou2: here is a list of drivers: https://github.com/openstack/kuryr/tree/master/kuryr/lib/binding/drivers , i imagine another driver is needed | 18:34 |
| lakerzhou2 | Hongbin, I was trying to read kuryr codes till 2am last night, still don't know how to do the binding for SR-IOV port | 18:35 |
| lakerzhou2 | hongbin, veth pair binding is quite simple. I think the only change in kuryr is the create_host_iface() | 18:36 |
| hongbin | lakerzhou2: i am not familiar with this part as well... | 18:36 |
| *** nicolasbock has quit IRC | 18:38 | |
| hongbin | lakerzhou2: perhaps we could go to the #openstack-kuryr channel, and ping the kuryr ptl | 18:38 |
| lakerzhou2 | hongbin, my plan is to walk through all the scenario and work with kuryr or neutron ppl to get it done later. For now, we will document it as a dependency. | 18:38 |
| hongbin | lakerzhou2: ack | 18:38 |
| lakerzhou2 | Hongbin, sure, the earlier the better | 18:38 |
| lakerzhou2 | hongbin, do you know PTL of kuryr? | 18:39 |
| hongbin | lakerzhou2: i know | 18:39 |
| hongbin | lakerzhou2: let me ping me right now | 18:39 |
| lakerzhou2 | hongbin, thanks, I am join the channel now | 18:39 |
| hongbin | lakerzhou2: it is the evening time for him right now, not sure if he is still here | 18:40 |
| lakerzhou2 | hongbin, no worries. I can ping him later. Basically, I believe we should use kuryr in stead of another remote driver. And there are some work required at kuryr side. Hopefully not big (not big as far as I can see). | 18:43 |
| hongbin | lakerzhou2: ack | 18:44 |
| lakerzhou2 | hongbin, thanks for the discussion, I will go back to my doc. It takes way more time than I thought. But I am half way through. | 18:45 |
| hongbin | lakerzhou2: np | 18:47 |
