KubeVirt's Evolution: Governance, Features, and Community Growth

Maintaining a healthy open source project amid competing company interests is hard. KubeVirt addresses this with its Enhancements (VEP) process and SIG governance, inspired by Kubernetes’ KEP framework, to enable transparent, community-driven development.
In this session, we’ll explain how KubeVirt adapted these practices, walk through the VEP lifecycle from proposal to graduation, and show how it enables collaboration across companies. Using the VirtualMachinePool feature as a real-world example, we’ll highlight how an NVIDIA engineer and a Red Hat core contributor worked together to deliver IaaS-style VM lifecycle management in Kubernetes.
Attendees will gain practical strategies for fostering effective open source collaboration and see how VEP is evolving to support new challenges, including AI/high-performance workloads and multi-hypervisor support, as KubeVirt moves toward CNCF graduation.
Join us to see how Kubernetes-inspired governance drives innovation and growth.

Measuring KubeVirt Performance and Scale with KWOK

KubeVirt’s sig-scale publishes the project’s scale and performance data after every release and now we want to share some new data and techniques: using simulation with KWOK. In this talk, we’ll explore how Kubevirt leverages KWOK (Kubernetes Without Kubelet) to simulate thousands of Nodes and VirtualMachineInstances (VMIs). We’ll demonstrate how this large-scale simulated environment enables stress testing of the Kubevirt control plane. Furthermore, we will share how kubevirt sig-scale evaluates the control plane behavior under extreme scale to help uncover scalability limits and performance bottlenecks as well as benefits of leveraging other simulation techniques like the virtual kubelet.

This session also covers simulated load generation, collection and aggregation of performance metrics, and visualization of data trends across releases to detect scalability and performance regressions.
