Description of problem:
Problem was found during the triage of tickets https://issues.redhat.com/browse/AITRIAGE-4003 https://issues.redhat.com/browse/AITRIAGE-3996 Common factors between these two tickets are that they are from the same customer and the cluster is installed with the following features Configured features: OVN network type, Proxy, Requested hostname, SNO In both cases The cluster operator "openshift-controller-manager" fails to come up and when the pod logs are queried, there is no log content. I have given some more details in the "reproduction" section below.
Software version: OpenShift 4.11
Please see the description above, I am unsure of what the exact triggers of this issue are as we don't have enough data to say with certainty.

Actual results:
The cluster operator "openshift-controller-manager" fails to come up and when the pod logs are queried, there is no log content.
Looking at the pod
omg get pods -n openshift-controller-manager NAME READY STATUS RESTARTS AGE controller-manager-fwkz7 0/1 Pending 0 1h28m
The YAML of the pod contains the following error...
containerStatuses:
- image: quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:fead5da1351abee9e77f5c46247c7947d6f9cf76b5bf7a8b4905222fe2564665
imageID: ''
lastState: {}
name: controller-manager
ready: false
restartCount: 0
started: false
state:
terminated:
exitCode: 137
finishedAt: null
message: The container could not be located when the pod was terminated
reason: ContainerStatusUnknown
startedAt: null
An attempt to acquire pod logs reveals that there are no logs available for the pod. So it's hard to determine why the pod would not stay up.
The cluster operator "openshift-controller-manager" should come up and stay up
Additional info: I have attached the must gather from the AITRIAGE tickets so that further investigation may take place
