My current ifcfg-em1 is :

[root at rhsdev1 network-scripts]# cat ifcfg-em1
# Generated by dracut initrd
DEVICE="em1"
ONBOOT=yes
NETBOOT=yes
UUID="fd67c34e-9aad-44b7-a980-b5288ad3c442"
IPV6INIT=yes
BOOTPROTO=dhcp
HWADDR="c8:1f:66:c6:d5:fc"
TYPE=Ethernet
NAME="em1"

I did this:

# systemctl stop NetworkManager.service ; chkconfig NetworkManager off;
systemctl restart network.service ; chkconfig network on

Note: Forwarding request to 'systemctl disable NetworkManager.service'.
rm '/etc/systemd/system/multi-user.target.wants/NetworkManager.service'
rm '/etc/systemd/system/dbus-org.freedesktop.NetworkManager.service'
rm '/etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service'
Job for network.service failed. See 'systemctl status network.service' and
'journalctl -xn' for details.

I modified em1 to:

[root at rhsdev1 network-scripts]#  cat ifcfg-em1

ONBOOT=yes
NETBOOT=yes
