It turned out that the latest DPDK I can manually compile on the

After looking at the table you pointed me, my best option was
OvS 2.14.9 with DPDK-v19.11.13.

the only error I saw in 'ovs-vsctl show' was related to the dpdk port. The

Regarding the "ring error", I'm fine with having it, as long as DPDK is able to

always the case).

OVS with DPDK support I'm receiving a build error related to libmnl not

Hello all,
I've started to look at the OVS-DPDK vxlan tunneling feature as well as the
different examples in openvswitch.org.
I have a few questions/notes on which I would be glad to have your opinion and
thoughts.
1. When configuring port as type vxlan the remote_ip option is a must.

Hi,
We recently tested ovs-dpdk, but we met some bandwidth issue. The bandwidth
from VM to VM was not close to the physical NIC, it's about 4.3Gbps on a
10Gbps NIC. For no dpdk (virtio-net) VMs, the iperf3 test can easily
reach 9.3Gbps. We enabled the virtio multiqueue for all guest VMs. In the
Hi all,
I am able to get expected performance using ovs dpdk on a single socket
system.
But on a system with 2 NUMA nodes, the throughput is less than expected.
The system has 8 physical cores each socket with hyperthreading enabled. So
total 32 cores.
Only one physical 10G interface is being
Hi,
I managed to solve this performance issue. I got improved performance after
turning off the mrg_rxbuf and increasing the rx and tx queue sizes to 1024.
Thanks,

Hi,
We figured out that the packet processing appliance within VM (which reads
from raw socket on the dpdk vhost user interface) requires more packets per
second to give higher throughput. Else its cpu utilization is idle most of
the times.
We increased the "tx-flush-interval" from default 0 to

Hi Onkar,
Thanks for shedding some light.
I don't think your difference in performance will have to do your
OvS-DPDK setup. If you're taking the measurements directly from the
iperf server side you'd be going through the "Internet". Assuming you
don't have a dedicated connection there, things

Thanks for your email. Your setup isn't very clear to me, so a few

Hi,
I have been experimenting with OVS DPDK on 1G interfaces. The system has 8
cores (hyperthreading enabled) mix of dpdk and non-dpdk capable ports, but
the data traffic runs only on dpdk ports.
DPDK ports are backed by vhost user netdev and I have configured the system
so that hugepages are
