Hi.  The ERR log above likely means that you reached the maximum
number of DPDK ports.  Most likely, your DPDK is built with default
max_ethports, which is 32, and your system has more devices.
You need to increase the value and re-build DPDK (and OVS afterwards),
or reduce the number of devices.

Best regards, Ilya Maximets.
