16:04:34 <acm> #info Al Morton
16:05:13 <srao> #info Timestamps to Log-files- Should we?
16:06:46 <srao> #info Adding timestamps doesn't hurt. Consolidation of logs can be taken in future.

16:07:20 <srao> #info Testapi Container running in Pod-12.
16:07:55 <srao> #info Add this config file: OPNFV_URL= http://10.10.120.22:8000/a
16:08:09 <srao> #info add this into config file: OPNFV_URL= http://10.10.120.22:8000/api/v1
16:08:28 <srao> #info Include this when running the test: --opnfvpod intel-pod12
16:11:06 <srao> #info Started to explore Cedric's XTesting - create ansible for Vsperf. Will update the team next week.
16:14:14 <srao> #info Started experimenting with newer versions of OVS-DPDK-VPP
16:14:36 <acm> #info Need to discuss gRPC & REST limits with Cedric.
16:15:17 <srao> #info DPDK 18.11, OVS 2.10, VPP 18.1.2
16:18:10 <srao> #info Hari: We have to remove these flags '--burst=64 -i --txqflags=0xf00 ', if we move to DPDK 18.11
16:20:38 <srao> #info: Support for libvirt. We have to move from qemu-system-x86_64 command to libvirt.
16:21:44 <srao> #info Why it helps to move to libvirt: (a) For short-duration we may not see any issues, however for longer durations there will be performance degradation.
16:21:49 <acm> #info qemu will eventually cause a few packets to drop with VPP
16:22:10 <acm> #info  estimate of 3 weeks development time
16:23:00 <srao> #info Why it helps to move to libvirt: (b) CPU pinning would be relatively easier
16:23:04 <acm> #info if we move to libvirt, the XML will tell qemu how to start, handled much more efficiently
16:24:02 <srao> #info Christian - With DPDK 18.11 We may have to enable legacy-memory option (--legacy-mem)
16:24:05 <acm> #info DPDK 18.11  might have to add legacy memory option, otherwise will see drops
16:24:30 <srao> #info Hari: --burst=64 i is still included, whereas disable-hw-vlan is not
