Proxmox VE

Creates a cloud-init template (VM 9000) on local-lvm. The local storage needs the Import content type (default on new Proxmox VE 9.1 installs). Adjust the storages, bridge and SSH key path to your setup.

In the web UI: Datacenter > Storage, edit local and add Import to its content; then on that storage, Import > Download from URL with the URL above and the SHA-256 checksum, and pick the downloaded file as the import source when adding the VM disk. On Proxmox VE 8, download the file with wget and use import-from=/root/almalinux-10-10.2-20261109.0-x86_64.qcow2 instead.

Keep images up to date

Automation should not scrape this page. The catalog index lists the latest version of every image with versioned URLs, SHA-256 and SHA-512 digests, sizes, firmware and the cosign identity; the version history of this image lists every published release. OpenStack operators using openstack-image-manager can point it at the ready-made definitions:

osism openstack-image-manager
curl -fsSo oic-images.yml https://images.openimages.cloud/osism/images.yml
openstack-image-manager --cloud admin --images oic-images.yml --latest

About

Cloud-init-ready, signed AlmaLinux 10 qcow2 image built from the official AlmaLinux GenericCloud release, verified against the upstream checksum list. Like RHEL 10 it needs an x86-64-v3 CPU (Haswell or newer) exposed by the hypervisor CPU model.
