The PMD start function is failing, unfortunately that error does not 
tell that much information.

I would suggest you to enable the debug of the vmxnet3 PMD in DPDK, set 
CONFIG_RTE_LIBRTE_VMXNET3_DEBUG_INIT=y in the config/common_base file of 
DPDK, then recompile DPDK and OvS.

Please try once again and send the terminal output, I hope we can get a 
more information of what is going on with that log.

Another thing to do would be to bind the NICs to the uio_pci_generic and 
VFIO modules, just to be sure that the issue is also present there.
