Fedora20将网卡名字改回eth0

近由于项目原因，自己安装了个Fedora20虚拟机环境，忽然发现Fedora20这个版本里的网卡名字有点怪怪的，不是传统的eth0，改成了ens33，觉得有必要改回来。上网搜索了一下，把这个别扭的ens33改成了eth0，看着顺眼多了。

记录操作步骤如下：

The easiest way to restore the old way Kernel/modules/udev rename your ethernet interfaces is supplying these kernel parameters to Fedora 19:

net.ifnames=0
biosdevname=0

To do so follow this steps:

Edit /etc/default/grub
At the end of GRUB_CMDLINE_LINUX line append "net.ifnames=0 biosdevname=0"
Save the file
Type "grub2-mkconfig -o /boot/grub2/grub.cfg"
Type "reboot"

If you didn't supply these parameters during the installation, you will probably need to adjust and/or rename interface files at /etc/sysconfig/network-scripts/ifcfg-*.

Up to Fedora 18, just biosdevname=0 was enough.

As an example, in a certain machine, in a exhaustive research, I got:

-No parameters: NIC identified as "enp5s2".
-Parameter biosdevname=0: NIC identified as "enp5s2".
-Parameter net.ifnames=0: NIC identified as "em1".
-Parameter net.ifnames=0 AND biosdevname=0: NIC identified as "eth0".
