我尝试过以下方法：

> ifconfig -a：不显示新的NIC信息或MAC.
>删除/etc/udev/rules.d/70-persistent-net.rules并重新启动.
>尝试使用真正的HwAddr创建一个新的ifcfg-eth2文件,但仍然显示：

Bringing up interface eth2:  
 Device eth2 does not seem to be present,delaying initialization. [Failed]

> rmmod ixgbe; modprobe ixgbe
> dmesg的输出：

这些都不起作用.
但我相信如果我格式化/重新安装操作系统它将完美地工作.
我在以前的服务器上遇到同样的问题.
如何在不重新安装操作系统的情况下解决此问题？

注意：这是在另一个全新安装的CentOS 6.5服务器上运行的相同NIC模型：
