Error:No suitable device found: no device found for connection "System eth0"解决方法

现象描述：
最近在克隆centos6系统机虚拟机迁移完成后，在克隆或者迁移的系统启动网卡报错然后就百度了下：报错信息：Error:No suitable device found: no device found for connection "System eth0"解决方法：删除/etc/udev/rules.d/70-persistent-net.rules文件，重启系统。如果上面的不起作用vim 编辑文件 /etc/udev/rules.d/70-persistent-net.rules ；对比下物理地址和网卡的标识，然后需要将eth0配置为文件更改成和该文件一致：
如：网络在启动的时候会去配置文件 /etc/udev/rules.d/70-persistent-net.rules 读取相应的信息，如：# PCI device 0x8086:0x100e (e1000) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:fb:0c:96", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"# PCI device 0x8086:0x100e (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:fb:0c:8c", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
vim etc/sysconfig/network-script/ifcfg-eth0
