解决克隆 Linux虚拟机后修改后的机器的ip、mac、uuid失败的问题

So here’s how we fix it:

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

 

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

 

Restart the VM

 

# reboot

 

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

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
