解决克隆 centos虚拟机后修改克隆后的机器的ip、mac、uuid失败的问题 – 四喜 – 博客园

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
