The steps on each node are: - create appropriate ifcfg-XXX files - stop NetworkManager - disable NetworkManager - enable network - start network You probably want to do the last 4 steps in one long command or else you will loose connectivity after stopping NetworkManager if you are not using a console.</blockquote><div> My current ifcfg-em1 is : [root@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" </div><div>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.
