Hello all,
Hi Sothy,
I followed the installion guide provided in the web site
https://github.com/openvswitch/ovs/blob/master/INSTALL.DPDK.md#ovstc
to install dpdk OVS.
I am rurnning Ubuntu 14.04 (kernel 3.13). It is a VM running VMware.
One intereface is enabled by VMXNET3.
It is not clear for me, are you trying to install OvS within the VM?
I used dpdk 16.04
Today I made clone of OVS (committ :bf32e3e2c029da18b5d6fd9210cb0ea12a1d0383).
The following are different configuration compared to above link.
sysctl -w vm.nr_hugepages=2048
Binded interface via igb_uio.
Then followed same configuration to start ovs-vsswitch with dpdk.
Can you please post the steps exactly that you followed? Which user you
were running as, etc? Can you also post how you expect packets to
arrive into the vm?
I am able to creatre bridge. When I create a port. It gives error message.
Please show the steps for this, too. The exact commands you used.
When I check ovs-vswitchd.log file,
There is warning that dpif_netlink|WARN|genric netlink family,
ovs_datapath does not exist. The openvswitch kernel module may be not
loaded.
This is definitely a problem. How did you start the ovs-vswitchd daemon?
This is not a problem Aaron, the ovs kernel module is not needed when
ovs is compiled with DPDK.
Then ERR: ERR|interface dpdk0 start error:operation not permitted.
The corresponding port is loaded by dpdk driver as shown in
dpdk_nic_bind --status.
After that I did sudo ovs-vsctl show. it show br and port details as well.
I am able to add one flow rule as well. But ovs bridge didnt get
packets from the interface.
Do you know why this error is popup? anyway to solve the problem?
Thank you very much
Best regars
Sothy

As Aaron wrote, having the exact commands is important to help you.
In addition I would recommend to use the test-pmd [1] application from
DPDK to check if the issue is also present in that case.
