Description Fernando F. Mancera 2022-06-07 13:51:21 UTC

This is a clone of https://bugzilla.redhat.com/show_bug.cgi?id=2077605 for RHEL 9.1

In OpenShift, we rebased on RHEL 8.6 and saw failures to install with ovn-kubernetes.  Oddly, this only happens on Azure some of the time.

However,  what appears to happen after restarting NetworkManager very rapidly after getting a lease, we DHCP again but the interface never gets the IP.  The logs say "ip4: set state fail (was pending, reason: check-ip-state)" -- what is check-ip-state?

I will attach a while journal, but the timeline I've pieced together looks like this:
