• "You must install the cluster by using bare metal infrastructure, either on-premise or through a supported cloud partner, with Red Hat Enterprise Linux CoreOS workers. "

My understanding was only the control or master nodes have dependency of Red Hat Enterprise Linux CoreOS. Is the highlighted workers in training document correct ? Or is it just the wordings which is confusing for me ? Based on my understanding worker or compute node can have either RHEL CoreOS or RHEL 8.6 and later,

@Ravi_Shanker You are right : https://docs.redhat.com/en/documentation/openshift_container_platform/4.8/html-single/architecture/i...

However, it is recommended to use all cluster machines with RHCOS.

On referring the document for "OpenShift Container Platform 4.14 - OpenShift Virtualization installation, usage, and release notes" 

Realized that OpenShift Virtualization indeed requires RHCOS worker nodes -
