The KubeVirt User Guide repository on GitHub provides comprehensive documentation and instructions for users who are interested in deploying, managing, and operating virtual machines (VMs) within Kubernetes clusters using the KubeVirt project. KubeVirt is an open-source tool that extends Kubernetes capabilities to include VM management, thus allowing users to run both containers and VMs in a single cluster environment. This hybrid approach leverages the strengths of containerization for microservices and virtual machines for legacy or full-stack applications.

The user guide repository is structured to cater to various audiences including developers, system administrators, and operators who are new to KubeVirt as well as those looking for advanced features and configurations. It offers a step-by-step approach, starting with an introduction to KubeVirt, explaining its components, architecture, and key concepts such as VM lifecycle management, storage options, networking, and security features.

For newcomers, the repository provides installation instructions that include prerequisites, setup guides, and deployment methods tailored for different environments. It covers topics like enabling the KubeVirt feature gate, setting up persistent volumes, configuring network interfaces, and using command-line tools such as `virtctl` to manage VMs. The guide also emphasizes best practices for securing VM deployments, integrating with cloud-native workflows, and ensuring high availability.

The repository includes detailed documentation on creating, starting, stopping, and deleting virtual machines using YAML definitions and the KubeVirt CLI. It guides users through customizing their VM configurations by detailing various disk types (e.g., directory, block, PVC), networking interfaces, and resource allocations like CPU and memory. Advanced topics such as live migration, snapshotting, and cloning are also covered, enabling users to manage their virtualized workloads more flexibly and efficiently.

In addition to user-focused documentation, the repository contains insights into developing with KubeVirt. It offers guidance on contributing code, testing, and using development tools. There are sections dedicated to API usage, understanding the underlying code structure, and building custom operators that extend KubeVirt’s functionality.

The KubeVirt User Guide is an evolving resource maintained by a community of contributors who work collaboratively to ensure it remains up-to-date with the latest features and best practices. It provides a comprehensive knowledge base for anyone looking to explore or deploy virtual machines in Kubernetes environments, making it an invaluable asset for organizations transitioning from traditional VMs to cloud-native architectures while still needing support for legacy applications.

Overall, the repository reflects KubeVirt’s commitment to integrating virtualization with container orchestration, promoting flexibility and scalability in modern IT infrastructures. By bridging the gap between containers and VMs, KubeVirt empowers organizations to embrace a unified infrastructure model that accommodates diverse workloads.
