[font=Helvetica, "]redhat7虚拟机默认安装之后，虚拟机网卡名称为eno16777728或者eno16777736,如下所示：
[font=Helvetica, "]

[font=Helvetica, "]1、修改/etc/sysconfig/grub或者/etc/default/grub，它们是一个文件，改谁都可以，需要添加参数，
[font=Helvetica, "] 给GRUB_CMDLINE_LINUX参数中增加net.ifnames=0 biosdevname=0。

[font=Helvetica, "]vim /etc/sysconfig/grub
[font=Helvetica, "]GRUB_CMDLINE_LINUX="rhgb quiet net.ifnames=0 biosdevname=0"

[font=Helvetica, "]

[font=Helvetica, "]接下来，生成系统引导文件
[font=Helvetica, "]grub2-mkconfig -o /boot/grub2/grub.cfg

[font=Helvetica, "] 2、修改网卡名称
[font=Helvetica, "] mv /etc/sysconfig/network-scripts/ifcfg-eno16777728 /etc/sysconfig/network-scripts/ifcfg-eth0
[font=Helvetica, "]vi /etc/sysconfig/network-scripts/ifcfg-eth0
[font=Helvetica, "] device=eth0
[font=Helvetica, "] name=eth0
[font=Helvetica, "] 一般这两步完成了，重启虚拟机，验证网卡即可，
[font=Helvetica, "]但是我这里需要第三步.
[font=Helvetica, "]

[font=Helvetica, "] 3、更改/etc/udev/rules.d/70-persistent-ipoib.rules，
[font=Helvetica, "]将其中的NAME="eno16777728"改为eth0
[font=Helvetica, "]vi /etc/udev/rules.d/70-persistent-ipoib.rules
[font=Helvetica, "]SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:12:95:65", NAME="eth0" reboot,
