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/-persistent-net.rules
[root@c1node01 ~]# reboot
………………
[root@c1node01 ~]# service network restart
Shutting down loopback insterface: [ OK ]
Bringing up loopback insterface: [ OK ]
Bringing up interface eth0: [ OK ]
