Description of problem:
Picked up 4.14-ec-4 (which uses cgroups v1 as default) and trying to create a cluster with following PerformanceProfile (and corresponding mcp) by placing them in the manifests folder,
apiVersion: performance.openshift.io/v2 kind: PerformanceProfile metadata: name: clusterbotpp spec: cpu: isolated: "1-3" reserved: "0" realTimeKernel: enabled: false nodeSelector: node-role.kubernetes.io/worker: "" machineConfigPoolSelector: pools.operator.machineconfiguration.openshift.io/worker: ""
and,
apiVersion: machineconfiguration.openshift.io/v1 kind: MachineConfigPool metadata: name: worker spec: machineConfigSelector: matchLabels: machineconfiguration.openshift.io/role: worker nodeSelector: matchLabels: node-role.kubernetes.io/worker: ""
The cluster often fails to install because bootkube spends a lot of time chasing this error,

This leads to worker nodes not getting ready in time, which leads to installer marking the cluster installation failed. Ironically, even after the cluster installer returns with failure, if you wait long enough (sometimes) I have observed the cluster eventually reconciles and the worker nodes get provisioned.
I am attaching the installation logs from one such run with this issue.
Version-Release number of selected component (if applicable):
4.14
How reproducible:
Often
Steps to Reproduce:
1. Try to install new cluster by placing PeformanceProfile in the manifests folder 2. 3.
Actual results:
Cluster installation failed.
Expected results:
Cluster installation should succeed.
Additional info:
Also, I didn't observe this occurring in 4.13.9.
