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/centos-stream-10-20261106.0-x86_64.qcow2 instead.
