Table of Content
Welcome to our monthly roundup highlighting project news, community writings, and resources devoted to the KubeVirt project!
In this issue we cover the v1.9.0-beta.0 pre-release, the disclosure of CVE-2026-7374 affecting virt-handler, a notable sovereign cloud adoption story from Swisscom, and several practical guides on KubeVirt live migration and deployment on SUSE Linux Enterprise.
This series is intended to be an open-source resource for developers, platform engineers, storage experts, and anyone interested in learning more about the ins-and-outs of Day 1 and Day 2 operations of virtual machines in containers with KubeVirt.
Project News
21-May: KubeVirt v1.9.0-beta.0 Released by The KubeVirt Community
Among the notable changes surfaced in the release notes are continued improvements around device passthrough and PCI topology, fixes for VM restart race conditions, and general hardening across the KubeVirt control plane. Release artifacts are available on the kubevirt/kubevirt releases page and pre-built containers are published on Quay.
26-May: Critical virt-handler Security Issue Disclosed
CVE-2026-7374 describes a critical KubeVirt vulnerability affecting virt-handler. An authenticated user with edit access in a namespace may be able to replace a VM console Unix socket with a symlink to the host container runtime socket, allowing virt-handler to connect to an unintended privileged endpoint on the node.
Community Meetings and Discussions
The KubeVirt community continues to meet weekly on Wednesdays, with SIG Performance & Scale meetings on Thursdays and SIG Storage bi-weekly meetings on Mondays.
Special Interest Groups
4-May: SIG-Network Meeting
The discussion included addressing GitOps challenges related to VM network interface persistence, evaluating a proposal for secondary network bandwidth abstraction , planning a breaking change to align network hot-plug/unplug operations with defined rollout strategies, and the status of Dynamic Resource Allocation (DRA) integration.
13-May: SIG-Compute Meeting
Topics included managing feature gates for beta-to-stable transitions and addressing security configuration challenges for live migration features, specifically regarding user_faultfd and seccomp profiles.
Community Meetings
06-May: Focused on progress toward the 1.9 GA release, scheduled for July 22.
13-May: Addressed the technical requirement to bump Kubernetes dependencies to 1.36 and update the Go builder image.
27-May: Discussed a proposal for adding new annotations to vert-launcher pods to support third-party networking controllers during cross-cluster live migrations.
The KubeVirt YouTube channel and the KubeVirt Community Calendar list upcoming sessions and newly posted archives.
Community Tutorials, Demos, and Best Practices
12-May: Swisscom Highlights KubeVirt in Sovereign Cloud Architecture
Swisscom published a case study on building a sovereign cloud platform powered by open source Kubernetes, KubeVirt, and Kube-OVN. The post underscores how KubeVirt is being positioned as a serious foundation for real-world, multi-tenant, production platforms in regulated and nationally significant environments.
07-May: Using KubeVirt on SUSE Linux Enterprise, by Jim Fehlig and Vasily Ulyanov
SUSE published an official guide for running KubeVirt on SLES 15 SP7. The guide explains the core KubeVirt components, covers install and configuration flow, and walks through enabling capabilities such as live migration and HostDisk, along with adding Containerized Data Importer (CDI) for disk import workflows.
8-May: Karpenter, KubeVirt, and the Limits of Managed Kubernetes, with YongKang He (KubeFM)
YongKang He, founder of KSUG AI, explains which Kubernetes tools he is watching closely, where managed abstraction stops helping, and why cost visibility, guardrails, and operator judgment still matter.
12-May: Using KubeVirt to run OpenVMS within a Kubernetes Cluster
In this presentation, Brett Cameron & Liam Bainsfair, Chief Application Services Officer and Operating Systems Specialist at VSI present Achieving high-availability in new ways – using KubeVirt to run OpenVMS within a Kubernetes cluster at VSI’s OpenVMS Bootcamp.
Upcoming KubeVirt Events and Talks
