Comment 3 for bug 1651727

Hello. Thanks for the information.

Let's try following scenario:
- Enable CPU pinning for Nova-compute, specify CPU list in nova.conf
- Isolate CPUs for nova in /etc/default/grub (reboot requires)
- Create flavor with 2 vCPUs and HugePages
- Spawn 2 VMs

Then you can use taskset command to run Iperf3 client/server on specific vCPU.
Also make sure that OVS pmd threads are not affected by nova vcpu pinning.

But generally speaking I can assume that this issue is not related to networking-ovs-dpdk. For more useful information you probably should take discussion in DPDK-users or OVS-discuss mailing lists.
