  2. 2p1nic vs 1p1nic (mackonstan, 17:14:54)
    1. Alec - proposal to add 1p1nic topologies (mackonstan, 17:15:08)
    2. OpenStack ML2/VPP/VLAN will use dot1q-l2bdbase-eth-2vhost-1vm (mackonstan, 17:15:18)
    3. OpenStack ML2/VPP/VLAN will use dot1q-l2bdbase-eth-2vhost-1vm (mackonstan, 17:15:22)
    4. adding following baseline topologies (mackonstan, 17:21:17)
    5. 1p1nic-dot1q-l2bdbase-eth-2vhost-1vm (mackonstan, 17:21:28)
    6. *** 1p1nic-ethip4vxlan-l2bdbase-eth-2vhost-1vm (mackonstan, 17:22:06)
    7. scale topology cases: 2p1nic-ethip4vxlan-l2bdscale-<n>flows-eth-<m>vhost-<o>vm-parallel (mackonstan, 18:11:21)
    8. ACTION: All - to agree on the most applicable combinations of <n>, <m>,<o> (mackonstan, 18:11:43)

    11. ACTION: Irene_ - working on optimizing and tuning testpmd in VM to work with 2vCPUs - 1vCPU for main testpmd app, and 1vCPU for pmd threads. Expecting progress on this next week, will send email to [csit-dev]. (mackonstan, 18:13:19)
    12. need to standardize on testpmd startup parameters (mackonstan, 18:13:48)
    13. ACTION: Irene: will send list of parameters optimized for using vpmd with virtio, and script examples (mackonstan, 18:13:57)
    14. review and update (nested) VM image building for vhost tests - starting point being existing CSIT VM image building: Ubuntu, Centos (mackonstan, 18:14:43)
    15. ACTION: team of volunteers (?): Carsten, PMikus, Alec, Thomas, Irene, Maciek (mackonstan, 18:14:53)
    16. Thomas - For baselining the system - Replace VPP with 2x testpmd for xconnecting 2x Phy-to-Vhost (mackonstan, 18:15:23)
    17. requires a new DPDK patch for enabling vhost in testpmd - <add-link> (mackonstan, 18:15:35)
    18. Irene currently testing manually in Intel labs - can help with onboarding into CSIT. (mackonstan, 18:16:21)
    19. All agreed to cover remaining open points and details over email thread on csit-dev. No need for another TWS call. Will be tracking progress and coordinating using CSIT comms means: csit-dev@lists.fd.io, #fdio-csit, CSIT weekly calls every Wednesday. Maybe another technical TWS call in January per Thomas suggestion. (mackonstan, 18:18:28)
