[ovs-discuss] OVS+DPDK issue on Ubuntu 16.04

Hi,
I beg a pardon but I'm not entirely clear what you mean with "... mount the
Intel 10gig ..."
Anyway what I've seen most often is that people struggle with some core
parts of the setup and then get refused by OVS trying to add the DPDK port.
What you report "...we are not able to add dpdk0 port to ovs bridge..."
sounds very similar.

In the past all questions I got only needed to check logs, identify the
issue in base ovs+dpdk setup and then things started to work for them.
Please take a look at
http://askubuntu.com/questions/786510/using-openvswitch-with-dpdk-in-ubuntu-16-04/789203#789203

If it helps you please give it an upvote and let me know.
I might consider adding this as a troubleshooting section to the
serverguide if this really is a common case.

Kind Regards,
Christian
