Openshift is Kubernetes+.
Openshift Virtualization Engine is kubevirt (aka kvm/libvirt).
That's a shame. We found a significant performance loss with kubevirt and nobody has ever really been able to explain it or make it go away. 15% throughput loss on an open source mq.

OKR for the open source kubernetes, kubevirt for the virtualisation part.
