I noticed some test pods are not scheduled:

The test uses a busybox container requesting "10m" CPU (i.e. 10 milliCPUs), which SHOULD fit any node in an idle OCP cluster (note this is serial test and nothing else should be running).
I filed https://github.com/kubernetes/kubernetes/pull/82245 to remove any CPU requirements, maybe it helps.
This is not a release blocker. It is passed https://prow.k8s.io/view/gcs/kubernetes-jenkins/logs/ci-kubernetes-e2e-gci-gce-serial/1182066659620294656 Update the status to Verified This job failed with same problem today (Oct/14): https://prow.svc.ci.openshift.org/view/gcs/origin-ci-test/logs/release-openshift-ocp-installer-e2e-azure-serial-4.2/86 Test passed in, https://prow.svc.ci.openshift.org/view/gcs/origin-ci-test/logs/release-openshift-ocp-installer-e2e-azure-serial-4.3/191 https://prow.svc.ci.openshift.org/view/gcs/origin-ci-test/logs/release-openshift-ocp-installer-e2e-azure-4.3/191 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
