KubeVirt is an open-source virtualization add-on for Kubernetes that enables you to run and manage traditional Virtual Machines (VMs) directly within your Kubernetes clusters. It seamlessly integrates VMs into the Kubernetes ecosystem, allowing you to manage both containerized and virtualized workloads using the same familiar tools and APIs.

• **Virtualization API:** KubeVirt extends the Kubernetes API with custom resource definitions (CRDs) for defining and managing VMs, treating them as first-class citizens alongside pods and other Kubernetes objects.
• **Unified Management:** KubeVirt allows you to manage VMs and containers through a single unified interface, simplifying operations and promoting consistency.
• **High Performance:** KubeVirt leverages the underlying virtualization capabilities of the host infrastructure, providing near-native performance for VMs running within Kubernetes.
• **Storage Integration:** KubeVirt supports various storage options, including persistent volumes, for storing VM disks and data.
• **Networking Integration:** VMs can be seamlessly integrated into Kubernetes networking, allowing for communication between VMs and pods.
• **Live Migration:** KubeVirt supports live migration of VMs between nodes in the cluster, minimizing downtime during maintenance or upgrades.

• **Unified Platform:** KubeVirt provides a single, unified platform for managing both containerized and virtualized workloads, simplifying operations and reducing complexity.
• **Flexibility:** You can choose the most appropriate workload type (VM or container) for each application, depending on its requirements and characteristics.
• **Portability:** KubeVirt enables the seamless migration of existing VM-based workloads to Kubernetes, unlocking the benefits of container orchestration and cloud-native technologies.
• **Scalability:** KubeVirt leverages Kubernetes's inherent scalability, allowing you to easily scale up or down your VM-based workloads as needed.
• **Cost Efficiency:** By running VMs on Kubernetes, you can potentially achieve better resource utilization and cost savings compared to traditional virtualization platforms.

While KubeVirt primarily operates through Kubernetes YAML manifests, here's a simplified example of a VirtualMachine definition:

```yaml apiVersion: kubevirt.io/v1 kind: VirtualMachine metadata:

 name: my-vm

 running: true
 template:
   spec:
     domain:
       resources:
         requests:
           memory: 1Gi
       devices:
         disks:
         - name: my-disk
           disk:
             bus: virtio
           volumeName: my-volume
     volumes:
     - name: my-volume
       persistentVolumeClaim:
         claimName: my-pvc

This manifest defines a VirtualMachine named “my-vm” with 1GB of memory, attached to a persistent volume claim named “my-pvc.”
