This is a series of posts to demonstrate how to install OKD 3.11 on oVirt and what you can do with it. Part I – How to install OKD 3.11 on oVirt How to install OKD 3.11 on oVirt (4.2 and up) Installing OKD or Kubernetes on oVirt has many advantages, and it’s also gotten a lot easier these days. Admins and users who want to take container platform management for a spin, on oVirt, will be encouraged by this. Few of the advantages are: Virtualizing the control plane for Kubernetes – provide HA/backup/affinity capabilities to the controllers and allowing […]

When running a virtualization workload on oVirt, a VM disk is ‘natively’ a disk somewhere on your network-storage.
Entering containers world, on Kubernetes(k8s) or OpenShift, there are many options specifically because the workload can be totally stateless, i.e
they are stored on a host supplied disk and can be removed when the container is terminated. The more interesting case is stateful workloads i.e apps that persist data (think DBs, web servers/services, etc). k8s/OpenShift designed an API to dynamically provision the container storage (volume in k8s terminology).
See the resources section for more details. […]
Hosted engine has seen a lot of progress and evolution, and today it is is the de facto recommended way to to deploy your oVirt Engine. But since that special Hosted Engine High Availability (HA) cluster itself needs management, we worked on making that be managed by the hosted engine itself, too.
Recent oVirt versions made it lot more easier to deploy hosted-engine, first by introducing the appliance and cloud-init customization
phase, next with VM configuration being stored on the shared storage and making the VM itself manageable from the UI itself. A few more under-the-hood changes resulted in storing […]
