标签:kvm network ifconfig eth0 mac地址
在KVM里安装的CentOS Linux系统。断电后重启系统,网络突然不通。
ifconfig -a|more没有看到eth0.。然后重启网络服务,报错如下:
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:
1.首先,打开/etc/udev/rules.d/70-persistent-net.rules
vi /etc/udev/rules.d/70-persistent-net.rules:
然后记录下来eth1网卡的mac地址。
2.打开/etc/sysconfig/network-scripts/ifcfg-eth0
vi /etc/sysconfig/network-scripts/ifcfg-eth0:
把DEVICE="eth0" 改成 DEVICE="eth1" ,
把eth0的当前HWADDR地址改成已经记录下来eth1网卡的mac地址。HWADDR="XX:XX:XX:XX:XX:XX".
3.最后,重启网络
service network restart
或者
/etc/init.d/network restart
这样,网络服务就正常了。
