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

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
