I modified em1 to:

IPV6INIT=yes
BOOTPROTO=dhcp
#HWADDR="c8:1f:66:c6:d5:fc"
Try enabling HWADDR= and set it to the proper MAC address.
NM_CONTROLLED=no
TYPE=Ethernet
NAME="em1"
Example that works for me:
DEVICE=eth0
HWADDR=68:11:34:19:63:a3
TYPE=Ethernet
BOOTPROTO=dhcp
NAME=eth0
ONBOOT=yes
NM_CONTROLLED=no
[root@rhsdev1 network-scripts]# service network restart
Restarting network (via systemctl): Job for network.service failed. See

*So in short, disabling NM and enabling/restarting network isn't working
as my network service is getting into error state
That can be caused by multiple things. Make sure the MAC address is
correct and make sure there are no routes lingering around before
starting the network service (they should be deleted before starting the
network service). Also https://access.redhat.com/solutions/26543
You can check the MAC address with:
# ip address show
You can check the routes with:
# ip route show
And delete where appropriate with:
# ip route del ....
Maybe it takes a while before things settle down after NetworkManager is
stopped. You could try to insert a "sleep 1" in your command before
starting the network service and see if that makes any difference.
