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
解决克隆 Linux虚拟机后修改后的机器的ip、mac、uuid失败的问题
