Alpha: KubeVirt support is currently in Alpha. Use at your own risk.

Overview

KubeVirt extends Kubernetes to support running virtual machines (VMs) alongside containerized workloads. It addresses the needs of teams that have adopted Kubernetes but still have VM-based workloads that cannot be easily containerized. With KubeVirt, VMs and containers share the same scheduling, networking, and storage infrastructure — managed through the same Kubernetes APIs. The Generic Ephemeral VM and Crossplane EC2 workload templates depend on KubeVirt being installed.

How It Works

Cluster Service — Installed once per cluster by an administrator. Once active, the cluster gains the ability to run virtual machines alongside containers. Workload templates like Generic Ephemeral VM depend on KubeVirt being installed first.

Prerequisites

  • Kernel-level virtualization support on cluster nodes (/dev/kvm must be accessible on nodes that will run VMs)
  • For nested virtualization (e.g. running VMs inside cloud VMs), the host hypervisor must support it
  • Sufficient node resources — VMs typically require dedicated CPU and memory allocations

Installation

  1. Open Terra and navigate to the Plugin Marketplace
  2. Search for "KubeVirt"
  3. Click Install
  4. Fill in the configuration fields below
  5. Click Confirm to deploy

Configuration

Install-Time Fields

Field Details
version select · Required · Default: v1.7.0
KubeVirt version to install
nested_virtualization boolean · Required · Default: false
Enable nested virtualization support (required when running VMs inside cloud VMs or hypervisors that support it)

Notes

  • This plugin is included in the KubeVirt Bundle — you can install KubeVirt and the Generic Ephemeral VM workload template together in one step from Terra
  • KubeVirt is Alpha in this plugin — production deployments should validate behaviour in a staging environment first
  • This plugin is editable — you can update the version and nested virtualization setting after install via Terra
  • Nested virtualization must be supported and enabled at the host hypervisor level; enabling this flag without host support will cause VMs to fail to start
  • After installing KubeVirt, install the Generic Ephemeral VM workload template to begin launching VMs from Genesis

  KubeVirt technology addresses the needs of development teams that have 
  adopted or want to adopt Kubernetes but possess existing Virtual Machine-based 
  workloads that cannot be easily containerized. More specifically, the technology 
  provides a unified development platform where developers can build, modify, and 
  deploy applications residing in both Application Containers as well as Virtual Machines 
  in a common, shared environment. (This is currently in Alpha. Use at your own risk.)
