Description of problem:

The ramdisk logs we get from IPA only include the output of dmesg, which by default does not include most NetworkManager log messages. This makes it difficult to debug problems like https://issues.redhat.com/browse/OCPBUGS-55315 and https://issues.redhat.com/browse/OCPBUGS-30974 that seem to be caused by network config happening at the IPA stage of deployment. These could be configuration problems in the environment, but there's no way to tell.

Version-Release number of selected component (if applicable):

 One of the bugs listed above is for 4.18, but this likely applies to all releases.

How reproducible:

    Always, although the bugs in question are intermittent. NetworkManager logs are never included in the ramdisk logs though.

Steps to Reproduce:

    1. Deploy a cluster
    2. Look at the ramdisk logs from metal3.
    3.
    

Actual results:

    Very few NetworkManager logs

Expected results:

    All NetworkManager logs
