description KubeVirt Overview

KubeVirt allows users to run virtual machines within a Kubernetes environment. It integrates virtualization with containerization, providing a single platform for managing both containers and VMs. This is useful for applications requiring traditional VM infrastructure alongside modern cloud-native deployments. Developers and operations teams utilizing Kubernetes benefit from this combined capability.

help KubeVirt FAQ

Why would I use KubeVirt instead of just regular Kubernetes containers?

KubeVirt is designed to run existing traditional Virtual Machines alongside containerized applications within a Kubernetes environment. This is highly beneficial for organizations looking to modernize their infrastructure without having to immediately rewrite legacy applications that require full VM operating systems.

How does KubeVirt run virtual machines inside Kubernetes?

KubeVirt delivers VM functionality to Kubernetes by using KVM (Kernel-based Virtual Machine) on the cluster's worker nodes. It treats virtual machines as native Kubernetes objects, allowing you to manage them using standard `kubectl` commands.

Is KubeVirt a project backed by major tech companies?

KubeVirt was originally developed by Red Hat to bridge the gap between virtualization and cloud-native technologies. It is now a graduated project within the Cloud Native Computing Foundation (CNCF).

Can I migrate my existing VMware VMs to KubeVirt?

Yes, you can migrate existing virtual machine disk images into the KubeVirt ecosystem, though it usually requires converting the disks to a compatible format like `qcow2`. Once imported, these VMs can run alongside your standard containerized applications.
