Fedora 39 (EOL 2024-11-26), Fedora 40 (EOL 2025-05-13), and Fedora 41 (EOL 2025-12-15) are all out of support and no longer receive security updates. This bumps the kubevirt CI test matrix to currently supported releases, distributing tests across Fedora 42 (supported until 2026-05-13) and Fedora 43 (supported until 2026-12-09) to keep multi-version coverage. - Add fedora-43 image entry to the kubevirt image-builder - Rename fedora39-* tests to fedora43-* (4 tests) - Rename fedora40-* tests to fedora43-* (2 tests) - Rename fedora41-* tests to fedora42-* (4 tests) - Update .gitlab-ci/kubevirt.yml testcase names - Regenerate docs/developers/ci.md All 10 existing Fedora test configurations (kube-router, calico-selinux, calico-swap-selinux, crio with/without SELinux enforcing, docker-calico, flannel-crio-collection-scale) are preserved.

KubeVirt Image Builder
Build and push KubeVirt VM disk images to quay.io for Kubespray CI testing.
How It Works
The Ansible playbook downloads upstream cloud images, converts them to qcow2, resizes (+8G), wraps each in a Docker image based on kubevirt/registry-disk-v1alpha, and pushes to quay.io/kubespray/vm-<os-name>:<tag>.
Prerequisites
- Docker,
qemu-img, Ansible - Push access to quay.io/kubespray (robot account
kubespray+buildvmimages)
Image Definitions
All OS images are defined in roles/kubevirt-images/defaults/main.yml.
Each entry specifies:
| Field | Description |
|---|---|
filename |
Downloaded file name |
url |
Upstream cloud image URL |
checksum |
Checksum for download verification |
converted |
true if the source is already qcow2, false if conversion is needed |
tag |
Docker image tag (usually latest) |
Usage
Build and push all images
cd test-infra/image-builder/
make docker_password=<quay-robot-token>
Add a new OS image
-
Add a new entry to
roles/kubevirt-images/defaults/main.yml:new-os-name: filename: cloud-image-file.qcow2 url: https://example.com/cloud-image-file.qcow2 checksum: sha256:<hash> converted: true tag: "latest" -
Build and push the image:
make docker_password=<quay-robot-token> -
Submit a PR with the
defaults/main.ymlchange so CI can use the new image. See #12379 for an example.
CI Validation
Build only
cd test-infra/image-builder/
make validate
This validation path runs locally and uses BuildKit, so it does not depend on SSH access to the remote builder host or a Docker daemon.
Build only for one image
cd test-infra/image-builder/
make validate-single image_name=ubuntu-2404
Runtime Variables
kubevirt_images_push(default:true): whenfalse, skip docker login/push/logout.kubevirt_images_selected(default:[]): list of image keys to build. Empty list builds all images.kubevirt_container_builder(default:docker): usebuildkitfor local CI validation without Docker daemon access.
