今天克隆的虚拟机,当需要多台虚拟机的时候,试用克隆真是方便,不过遇到了
Device eth0 does not seem to be present 的问题,在网上找到遇到同样问题的解决方法,
很顺利的解决,记录之:

ifconfig…没有看到eth0.。然后重启网卡又报下面错误。

故障现象:

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]

CentOS Linux解决Device eth0 does not seem to be present

解决办法:
 
 
首先,打开/etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示:

# vim /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.
# PCI device 0×1022:0×2000 (pcnet32)
SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==”08:00:27:7e:8c:e7″, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth0″
# PCI device 0×1022:0×2000 (pcnet32)
SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==”08:00:27:30:c2:57″, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth1″

记录下,eth1网卡的mac地址08:00:27:30:c2:57

接下来,打开/etc/sysconfig/network-scripts/ifcfg-eth0

# vim /etc/sysconfig/network-scripts/ifcfg-eth0

将 DEVICE=”eth0″ 改成 DEVICE=”eth1″ ,
将 HWADDR=”08:00:27:7e:8c:e7″ 改成上面的mac地址 HWADDR=”08:00:27:30:c2:57″

 

这里需要用到vim的复制y  粘贴p

 

如果当前正处于编辑模式,需要先按下ESC键,再按下键盘上的ctrl+v键(一般状态只需要按下 ctrl+v),此时编辑框内的最下方将出现“可视 块”的提示字样。

使用方向键移动光标,选择矩形区域内的文字。

按下 y 键,复制所选文本。

用方向键移动光标到需要粘贴的位置处,再按下 p 键粘贴。

 

 

最后,重启网络

# service network restart
或者

# /etc/init.d/network restart

正常了,搞定
