Goal

Popular Linux distro like Centos, Fedora, RHEL and, in the future, RHCOS are delivered as bootc images.

As part of the Red Hat portfolio, I'd like to have OpenShift Virtualization able to consume bootc images to better align with other products.

User Stories

• As a VM owner, I want to be able to import and boot a VM from an existing external bootc image, so that I can consume bootc releases of my preferred OSes.

• As an HyperShift user I'd like to be able to create a Kubevirt managed Hosted Cluster directly using the bootc image for RHCOS on my nodes (VMs).

Non-Requirements

• List of things not included in this epic, to alleviate any doubt raised during the grooming process.

Notes

• the bootc project is already delivering bootc-install-to-disk, bootc-install-to-filesystem, bootc-install-to-existing-root utilities. As the first step, can we simply rely on them in the CDI Importer to extract the bootc image to a PVC?
• bootc images CI is already implementing a test lane for bootc images based on libvirt where bootc install to-disk is used to extract the image content to a raw disk
