虚拟机克隆 发现service network restart 启动失败
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]
解决办法一：
首先，打开/etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示：
# vi /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 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8f:89:9
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:1
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
记录下，eth1网卡的mac地址00:0c:29:50:bd:17
接下来，打开/etc/sysconfig/network-scripts/ifcfg-eth0
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
将 DEVICE="eth0" 改成 DEVICE="eth1" ,
将 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址 HWADDR="00:0c:29:50:bd:17"
最后，重启网络
# service network restart
或者
# /etc/init.d/network restart
正常了。
方法二：
步骤
1、
vi /etc/sysconfig/network-scripts/ifcfg-eth0
ifcfg-eth0的配置文件里保存了以前的MAC地址，就把这一行删除掉在重启网卡
2、
rm -rf /etc/udev/rules.d/70-persistent-net.rules 删除后重启机器
