So I'd expect that it is hard for someone out there whatever you pick :-/ That said I'd not pick any default by dpdk.org. In my case I thin I just "left" the linkage discussions too early and by that forgot to implement RTE_EAL_PMD_PATH which I now did. If there are no PMDs at all or no matter how many PMDs where there it can't probe something the error messages might point a bit more towards the RTE_EAL_PMD_PATH. E.g. no drivers found, please make sure you have PMDs for your network devices in And if RTE_EAL_PMD_PATH is "" (=disabled) let them know that as well. And finally one might suggest trying with EAL option -d. To then give up and die - just with more words before :-) That might help. -- Christian Ehrhardt Software Engineer, Ubuntu Server Canonical Ltd
