网络地址转换（NAT）模式下，将虚拟机的网卡enp0s3转换为eth0

    cd /etc/sysconfig/network-scripts
    cp ifcfg-enp0s3 ifcfg-enp0s3.bak
    mv ifcfg-enp0s3 ifcfg-eth0

    vim ifcfg-eth0
    更改: NAME=eth0, DEVICE=eth0, ONBOOT=yes

 cp /etc/default/grub /etc/default/grub.bak
 vim /etc/default/grub

GRUB_CMDLINE_LINUX的最后，加上 net.ifnames=0 biosdevname=0 的参数:
GRUB_CMDLINE_LINUX=”rd.lvm.lv=rootvg/usrlv rd.lvm.lv=rootvg/swaplv crashkernel=auto vconsole.keymap=us rd.lvm.lv=rootvg/rootlv vconsole.font=latarcyrheb-sun16 rhgb quiet net.ifnames=0 biosdevname=0”

grub2-mkconfig -o /boot/grub2/grub.cfg

reboot
