What're the FLOSS technologies underlying OpenShift? Sounds like KVM?

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.

Probably kubevirt if I had to guess (which would then use KVM under the hood)

  • Yes you are correct, it is kubevirt and leveraging KVM as the hypervisor coupled with the QEMU/Libvirt userspace pieces.
