Here is a small tip not to say so much nonsense, my environment is the CentOS operating system, and then I do not want to frequent unattended installation too troublesome, I would like to add a new virtual host will use the Clone this function.

Then I have a new customer long a device, very fast, but the network card can not be started, will report an error:

Device eth0 does not seem to be present, delaying initialization

The reason is that you this new virtual machine is a passenger, the network card above the MAC address is the customer machine tools, so we want to generate a new belongs to our own MAC address. The operation is simple, three steps:

First step: Vi/etc/sysconfig/network-scripts/ifcfg-eth0

HWADDR=00:0C:29:9A:2E:C3 #将这一行删除掉 (I generally even uuid= "26598398-7fe0-4099-8b9d-7a161838ec7c" This line also deleted)

Step Two: Rm-rf/etc/udev/rules.d/70-persistent-net.rules #此文件绑定了网卡和mac地址

Step Three: Reboot #重启操作系统

At this point, the system restarts to restart the network card.

PS: (If your network card has not been started, look at the network card parameters Onboot=yes is not changed from No to Yes)
