Hi Peter, Traffic generation used to be gated by a phase that tries to make sure packets are flowing in both directions at low rate (used to be 100pps). This means that as soon as we seen packets flowing in both directions, traffic generation at requested rate will start. Is that not sufficient in your case?
I’d like to note that we had some gating issues for multi-chain support – where the traffic generation was started too early due to a flaw in the gating logic (https://jira.opnfv.org/projects/NFVBENCH/issues/NFVBENCH-56?filter=allissues) But this has been fixed recently by using an algorithm that actually checks the src MAC or returning frames. So perhaps you ran into the same issue? The important point in your case is to understand how soon traffic can be blasted after the first packet comes back in each direction. Typically forwarders that use MAC learning only need the first packet to go through to guarantee optimal forwarding conditions. If your SUT requires a pause, this can be added to NFVbench relatively easily.

When I start the test, NFVBench is blasting traffic immediately and not setting up a flow, as a result there incur some initial losses as the flows are being added to the kernel and dpdk. My question is it possible to postpone the start of measurement with a few sec after traffic generation started?

This VM has VPP L3 routing included and that can be enabled/configured using the cloud-init file. How well it will perform will really depends on your virtio network emulation (for example if you use OVS, it will likely not go very fast and start dropping packets very early). Anyway, I can only help you to some extent as this stretches beyond what NFVbench handles.

With the latest versions of NFVbench, the testpmd VM image is included in the docker container itself (that way we make sure NFVbench always uses the right version of the VM image). May I ask why you want to access this VM image? To use it you will need to pass the proper config file to configure the forwarding dest MAC addresses (this is taken care of by NFVbench through openstack). If use openstack you do not need to manually get the qcow2 image and upload because it is done by NFVbench when using the PVP and PVVP chain types. If you still need the VM qcow2 file, you can simply copy it out from the container using “docker cp” command.
