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

  Probably kubevirt if I had to guess (which would then use KVM under the hood)
  • houseofzeus 2y ago
    Yes you are correct, it is kubevirt and leveraging KVM as the hypervisor coupled with the QEMU/Libvirt userspace pieces.

  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.

      Do you have the RH case number / Jira issue? I can take a look.

  https://github.com/kubevirt https://github.com/kubevirt specifically for OpenShift Virtualization
• whalesalad 2y ago
  everything ultimately boils down to kvm or qemu, usually
• jaitaiwan 2y ago
  OKR for the open source kubernetes, kubevirt for the virtualisation part.
