The upstream capk ubuntu images can be created using the image-builder project. https://github.com/kubernetes-sigs/image-builder

to build new images, checkout the image-builder project. Then navigate to the images/capi folder. The makefile in this directory can help build an image for cluster-api-provider kubevirt

Example command

PACKER_FLAGS="--var 'kubernetes_rpm_version=1.26.0-0' --var 'kubernetes_semver=v1.26.0' --var 'kubernetes_series=v1.26'  --var 'kubernetes_deb_version=1.26.0-00' --var 'disk_size=10240'" make build-kubevirt-qemu-ubuntu-2004

New images for k8s 1.27, 1.28, 1.29 and 1.30 are needed. To verify the latest image works, update the capk e2e tests to use the latest image (1.30) once that container disk is uploaded.

Ask rhn-engineering-dvossel if you need permissions to upload to the quay.com/capk repo
