centos虚拟机复制后网络重启出错解决

参考：http://blog.csdn.net/xluren/article/details/38986667

执行service network restart后出现如下错误

FAILED:

Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization.

产生原因

Bringing up interface eth0:  Device eth0 does not seem to be present, delaying initialization.产生原因一般是由于在linux下的虚拟机的修改，clone等操作。

解决方法：

1.修改Centos虚拟机克隆机的HWADDR为ifconfig -a的MAC地址 
形如：HWADDR=00:0C:29:90:A7:23，编辑ifcfg-eth0文件，将HWADDR值改为ifconfig -a中对应的mac地址，如下：

[root@c1node01 ]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

2.然后再做以下操作 

[root@c1node01 ~]# rm -rf /etc/udev/rules.d/70-persistent-net.rules 

[root@c1node01 ~]# reboot 

……………… 
[root@c1node01 ~]# service network restart
