一.故障现象：

[root@c1node01 ~]# service network restart

Shutting down loopback insterface:                                                       [   OK  ]

Bringing up loopback insterface:                                                            [   OK  ]

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

解决办法：

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

[root@c1node01 ~]#

二.另一种方法

造成这样的原因，是因为在虚拟机（Vmware）中移动了Centos系统对应的文件，导致重新配置时，网卡的MAC地址变了，输入ifconfig -a,找不到eth0

·······

安装完一个centos虚拟机，又拷贝一份，开机后网卡无法正常启动，报错：Device eth0 does not seem to be present, 
delaying initialization

解决：# mv /etc/sysconfig/network-scripts/ifcfg-eth0 
sysconfig/network-scripts/ifcfg-eth1

vim 
sysconfig/network-scripts/ifcfg-eth1

修改DEVICE="eth0" 
为DEVICE="eth1"

可删掉uuid、物理地址

然后重启启动网卡尝试下

三.比第一种更深入一点
