      workaround:

      Don't use ensX format.

      add net.ifnames=0 biosdevname=0 to GRUB_CMDLINE_LINUX

      [root@acs ~]# vi /etc/default/grub
      :
      GRUB_CMDLINE_LINUX="vconsole.keymap=jp106 crashkernel=auto vconsole.font=latarcyrheb-sun16 rhgb quiet net.ifnames=0 biosdevname=0"
      :
      [root@acs ~]# grub2-mkconfig -o /boot/grub2/grub.cfg

      And
      Edit /etc/sysconfig/network-scripts/ifcfg-ensX

      ensX-> ethX

      [root@acs ~]# reboot
