EAL: Error - exiting with code: 1 Cause: No probed ethernet devices - check that CONFIG_RTE_LIBRTE_IGB_PMD=y and that CONFIG_RTE_LIBRTE_EM_PMD=y and that CONFIG_RTE_LIBRTE_IXGBE_PMD=y in your configuration file Is that with IVSHMEM device or physical devices? I guess it is physical device problem? Thank you Sothy
