关于virulbox克隆了centos6.0最小化安装后如何使网卡能够上网

Posted 2020-10-31

解决办法：

 

So here’s how we fix it:

1. Remove the kernel’s networking interface rules file so that it can be regenerated

    

   # rm -f /etc/udev/rules.d/70-persistent-net.rules

    

2. Restart the VM

    

   # reboot

    

3. UPDATE your interface configuration file

    

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

   Remove the MACADDR entry or update it to the new MACADDR for the interface (listed in this file: /etc/udev/rules.d/70-persistent-net.rules).

   Remove the UUID entry

   Save and exit the file

4. Restart the networking service

    

   # service network restart

    

Happy cloning!

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"

修改IP地址，删除mac地址（HWADDR），删除UUID项。
然后重启启动网卡尝试下
