Rhel 7.2 installations.
rhel/centos installer creates simple network-scripts for existing adapters. They don't start automatically.
NetworkManager sees them with names
On Centos it's enough to delete the network scripts created by the installer to make NM create and activate in-memory connections with dhcp:
rm -f /etc/sysconfig/network-scripts/ifcfg-enp*
After reboot the connections appear in
Wired connection n and activate.
But on Rhel I don't see them in nmtui after deleting the scripts. The list is empty.
Why do I need this? Because it's a virtual machine and adapter names may change when I move it to another host.
