NetworkManager ships an empty configuration file (or better: with only comments). This is intended.

The default on rhel-8 is already "plugins=ifcfg-rh" (which is the same as "plugins=ifcfg-rh,keyile") (while on Fedora 33+ it is "plugins=keyfile,ifcfg-rh").

The setting in NetworkManager.conf is commented out to show what the default is. Uncommenting it, has little effect.


Except, if would have an effect if you had

  /usr/lib/NetworkManager/conf.d/10-some.conf
  > [main]
  > plugins=something

then having 

  /etc/NetworkManager/NetworkManager.conf
  > [main]
  > plugins=ifcfg

would make a difference.


Run `sudo NetworkManager --print-config` to see the configuration.

This fix updated the configfile for you 
https://github.com/openshift/machine-config-operator/commit/a2815aa4993954ec6f30785c8c0a1d0a79109a4b
and it was merged to 4.7

Comment 15 Tim Rozet 2021-03-24 17:55:46 UTC
The above fix was merged a few days ago into 4.7: https://github.com/openshift/machine-config-operator/pull/2426

So it makes sense it suddenly started working for you. But you probably need the cloned-mac-address fix as well.
