一.故障现象：
[root@01 ~]# 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@01 ~]# rm -rf /etc/udev/rules.d/70-persistent-net.rules
[root@01 ~]# reboot ………………
[root@01 ~]# service network restart
Shutting down loopback insterface: [ OK ]
Bringing up loopback insterface: [ OK ]
Bringing up interface eth0: [ OK ]
[root@01 ~]#
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"
删除uuid ,物理地址
然后重启启动网卡尝试下
