I’m using a Xena tester, with the following PVP script:

https://github.com/chaudron/ovs_perf

The config I use is:

~/ovs_perf/ovs_performance.py -d -l testrun_log.txt \
    --tester-type=xena --tester-address 10.19.188.64 --tester-interface 6,1 \
    --ovs-address $DUT \
    --ovs-user root --ovs-password $DUT_PW \
    --dut-vm-address 192.168.122.164 \
    --dut-vm-user root --dut-vm-password root \
    --virtual-interface tapVM \
    --dut-vm-nic-pci=0000:00:02.0 \
    --dut-vm-nic-queues=1 \
    --physical-interface eno1 \
    --physical-speed=10 \
    --stream-list=10,100,1000 \
    --packet-list=64,256,1024 \
    --warm-up --warm-up-no-fail --warm-up-time=5 \
    --skip-pv-test \
    --flow-rule-type=port \
    --testpmd-startup-delay=8 \
    --no-bridge-config
