在CORE中，执行 /root/.core/configs/m-MPE-manet.imn
但是，不能正常初始化。
查看日志文件 /var/log/core-daemon.log ，内容如下，有RTNETLINK错误。
解决办法，参考 http://blog.csdn.net/zahuopuboss/article/details/8678570

如果有报错
RTNETLINK answers: No such file or directory

需要安装kernel-modules-extra
使用uname -r查看内核版本
使用命令 yum install kernel-modules-extra-`uname -r`进行安装
