| hongbin | kevinz: listening | 04:00 |
| kevinz | hongbin: Today someone asked me about the mascot. I guess we can put the mascot to the wiki page or github readme | 04:01 |

| lakerzhou | Hi Hongbin | 18:18 |
| hongbin | lakerzhou: hi, you have some time ? want to learn from you about the nfv use cases | 18:18 |
| lakerzhou | Hongbin, I got your comments about snapshot, will have a new patch today | 18:19 |
| hongbin | lakerzhou: ack | 18:19 |
| lakerzhou | Hongbin, sure, I have time now to discuss | 18:19 |
| hongbin | lakerzhou: i wanted to drive zun to satisfied the nfv use cases | 18:20 |
| hongbin | lakerzhou: i am triying to figure out the steps to achieve the goal | 18:20 |
| hongbin | lakerzhou: i mainly wonder what are the steps to go there and how to do that one by one | 18:21 |
| lakerzhou | the main concern of NFV is performance/security. VNFs usually require multiple network | 18:21 |
| pksingh | just consuming some intelligent discussion in passive mode :) | 18:21 |
| lakerzhou | VNFs require support of CPU pinning, NUMA, hugepage | 18:22 |
| hongbin | i see | 18:23 |
| lakerzhou | so this in turn requires physical resource constraints for scheduling | 18:23 |
| hongbin | for example ? | 18:24 |
| lakerzhou | some policy related scheduling is also required for HA purpose, for example affinity and anti-affinity | 18:24 |
| hongbin | i see | 18:25 |
| lakerzhou | now, cpu-pining and numa can be done through flavor | 18:25 |
| lakerzhou | but I don't have knowledge of what is future nova scheduling implementation for such requirement | 18:25 |
| hongbin | i see | 18:26 |
| lakerzhou | basically, in flavor, you can define if a NFV requires CPU pinning or not | 18:26 |
| hongbin | i see | 18:26 |
| lakerzhou | only certain compute nodes can provide cpu-pinning capability | 18:26 |
| lakerzhou | so nova scheduling will do the match | 18:27 |
| hongbin | i see | 18:27 |
| hongbin | so from the features point of view, cpu pinning and numa would be the two features to add ? | 18:28 |
| lakerzhou | once the scheduling part is done, VNF pinned to specified CPUs or NUMA nodes. This is especially important for fast data packet handling through DPDK. | 18:28 |
| hongbin | i see | 18:29 |
| lakerzhou | which is commonly used by VNFs (and the host, e.g. OVS-DPDK) | 18:29 |
| *** pksingh has quit IRC | 18:29 | |
| lakerzhou | SR-IOV is also an alternative for DPDK, but it is less portable | 18:29 |
| hongbin | i see | 18:30 |
| lakerzhou | in another word, we need to provide flexible networking options, e.g. SR-IOV and OVS-DPDK | 18:31 |
| hongbin | i see | 18:31 |
| hongbin | i need to learn more about these two things :) | 18:31 |
| lakerzhou | DPDK support for container networking can be challenging now, even for intel virtual driver. I did not follow up in the past 6 months also. The old driver could not do this yet for docker container. | 18:32 |
| hongbin | i see | 18:33 |
| hongbin | this one: http://dpdk.org/ | 18:35 |
| hongbin | does nova support either SR-IOV or OVS-DPDK | 18:36 |
| lakerzhou | it is mainly neutron feature | 18:37 |
| lakerzhou | nova do the scheduling part | 18:37 |
| hongbin | i see | 18:37 |
| lakerzhou | I have another meeting scheduled in 5 minutes | 18:37 |
| hongbin | sure | 18:38 |
| lakerzhou | but we can continue the discussion later. | 18:38 |
| hongbin | i guess i got the initial information to start with :) | 18:38 |
| hongbin | sure | 18:38 |
| hongbin | i will try to summarize what we discussed in an etherpad | 18:38 |
| hongbin | then we can revisit it from time to time | 18:38 |
| hongbin | https://etherpad.openstack.org/p/zun-nfv-use-cases | 18:39 |
| lakerzhou | great, I hope we can generalize the sandbox to VM or baremetal | 18:39 |
| lakerzhou | sounds good, I will add more to the etherpad | 18:39 |
