Chapter 1. About OpenShift Virtualization
Learn about OpenShift Virtualization’s capabilities and support scope.
1.1. What you can do with OpenShift Virtualization
OpenShift Virtualization is an add-on to OpenShift Container Platform that allows you to run and manage virtual machine workloads alongside container workloads.
OpenShift Virtualization adds new objects into your OpenShift Container Platform cluster by using Kubernetes custom resources to enable virtualization tasks. These tasks include:
- Creating and managing Linux and Windows virtual machines
- Connecting to virtual machines through a variety of consoles and CLI tools
- Importing and cloning existing virtual machines
- Managing network interface controllers and storage disks attached to virtual machines
- Live migrating virtual machines between nodes
An enhanced web console provides a graphical portal to manage these virtualized resources alongside the OpenShift Container Platform cluster containers and infrastructure.
OpenShift Virtualization is designed and tested to work well with Red Hat OpenShift Data Foundation features.
When you deploy OpenShift Virtualization with OpenShift Data Foundation, you must create a dedicated storage class for Windows virtual machine disks. See Optimizing ODF PersistentVolumes for Windows VMs for details.
You can use OpenShift Virtualization with the OVN-Kubernetes, OpenShift SDN, or one of the other certified default Container Network Interface (CNI) network providers listed in Certified OpenShift CNI Plugins.
1.1.1. OpenShift Virtualization supported cluster version
OpenShift Virtualization 4.10 is supported for use on OpenShift Container Platform 4.10 clusters. To use the latest z-stream release of OpenShift Virtualization, you must first upgrade to the latest version of OpenShift Container Platform.
