[root@acs ~]#


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
