KubeVirt is a virtual machine management add-on for Kubernetes. The aim is to provide a common ground for virtualization solutions on top of Kubernetes.

Note: KubeVirt is a heavy work in progress.


Virtualization extension for Kubernetes

At its core, KubeVirt extends Kubernetes by adding additional virtualization resource types (especially the VM type) through Kubernetes's Custom Resource Definitions API. By using this mechanism, the Kubernetes API can be used to manage these VM resources alongside all other resources Kubernetes provides.

The resources themselves are not enough to launch virtual machines. For this to happen the functionality and business logic needs to be added to the cluster. The functionality is not added to Kubernetes itself, but rather added to a Kubernetes cluster by running additional controllers and agents on an existing cluster.

The necessary controllers and agents are provided by KubeVirt.

As of today KubeVirt can be used to declaratively

  • Create a predefined VM
  • Schedule a VM on a Kubernetes cluster
  • Launch a VM
  • Stop a VM
  • Delete a VM



To start using KubeVirt

Try our quickstart at kubevirt.io.

See our user documentation at docs.kubevirt.io.

To start developing KubeVirt

To set up a development environment please read our Getting Started Guide. To learn how to contribute, please read our contribution guide.

You can learn more about how KubeVirt is designed (and why it is that way), and learn more about the major components by taking a look at our developer documentation:


If you got enough of code and want to speak to people, then you got a couple of options:

Submitting patches

When sending patches to the project, the submitter is required to certify that they have the legal right to submit the code. This is achieved by adding a line

Signed-off-by: Real Name <email@address.com>

to the bottom of every commit message. Existence of such a line certifies that the submitter has complied with the Developer's Certificate of Origin 1.1, (as defined in the file docs/developer-certificate-of-origin).

This line can be automatically added to a commit in the correct format, by using the '-s' option to 'git commit'.
