I get the following error:

And in the logs:

I don't know anything about mellanox but I think you may not be linked
properly to the dpdk library. Does your library include all the other
libraries in libintel_dpdk.a if you built dpdk for combined libraries,
CONFIG_RTE_BUILD_COMBINE_LIBS=y. Also, did you build ovs to link in the
dpdk libraries. ./configure --with-dpdk=$DPDK_BUILD
Also, did you bind your mellanox nic to the dpdk PMD before starting
OVS. Fairly detailed instructions are in README.DPDK.md.
Also, which version of ovs are you using. The top of master now supports
dpdk 2.0.0. OVS seems to be trying to create a vhost device.
--TFH
It seems like the dpdk0 can't be created.
How does ovs assign the dpdkX to physical port? is there some parameter i
can pass? any chance it has some Intel specific code?
Any ideas what prevent it from being created?
There is a good chance i am missing something very basic so if this is the
case sorry in advance for that! thanks in advance!
Some more info:
