Hi There,
I downloaded the master branch from github and tried to setup OVS with DPDK
mode under Ubuntu16.04 kernel_4.4.0-21-generic. However I encountered below
error while I was trying to add a dpdk port to the OVS bridge.
Is this an issue if you run ovs-vswitchd without --detach option ? (ie
not as detached process) ?.
Thanks,

I followed the
INSTALL.DPDK.md<https://github.com/openvswitch/ovs/blob/master/INSTALL.DPDK.md>
but this error was consistently hit on Ubuntu16.04. Previously we tried OVS on
Ubuntu14.04 but it looked fine without this failure. Did you see any similar error on
your side or any comments about the failure?
Thanks a lot in advance!
Best Regards,
Alex
