It's kernel bug. I got same message in Redhat 6.3 and 6.4. After install a custom 3.4 kernel, everything is fine. Ubuntu 12.04 with 3.2 kernel is fine too. ------------------ 原始邮件 ------------------ 发件人: "dvr"; 发送时间: 2013年6月24日(星期一) 晚上7:53 收件人: "dev"; 主题: [dpdk-dev] The packages needed on CenOS hi,all I installed andconfigured DPDK follow the steps described in DPDK Getting Started Guide. but when I perfom the testpmd ,the following error message appers: No probed ethernet devices - check that CONFIG_RTE_LIBRTE_IGB_PMD=y and CONFIG_RTE_LIBRTE_IXGBE_PMD=y in your configuration file. How could this happen? I see that there are some packages needed when using Fedora 14, but the system I used is CenOS the kernel-version is :2.6.32-279.el6.x86_64 Is there any package I need to install on this system? Thank very much for any replay!< /div> Regards Maria
