Cloud Hypervisor has implemented a No AI code policy to decline contributions that may involve AI-generated content, aiming to mitigate legal risks and ensure compliance with licensing. Despite this precaution, concerns have been raised about the effectiveness of this policy, as contributors may still inadvertently incorporate AI assistance in their code. The latest version also expands the support for virtual CPUs and includes enhancements for running Windows 11 guests.

Flintlock is a community-driven service for creating and managing microVMs on host machines, supporting Cloud Hypervisor and Firecracker VMMs. Initially developed by Weaveworks for Kubernetes clusters, it is now useful for a variety of lightweight virtualization needs, with features for lifecycle management and metrics exposure. Contributions and feedback are encouraged from the community.

The article presents Katakate's k7, a self-hosted infrastructure designed for creating lightweight virtual machine (VM) sandboxes to safely execute untrusted code. It supports a command-line interface, API, and Python SDK, leveraging technologies like Kubernetes, Kata, and Firecracker for efficient VM management. Currently in beta, it offers features for serverless applications, CI/CD runners, and blockchain execution, while being open-source under the Apache-2.0 license.
