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/trove-guest-image-2026.2-amd64.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.

About

Signed guest image for Trove, built from openstack/trove (pinned commit per series) with diskimage-builder: Ubuntu 24.04 minimal, the Trove guest agent and Docker CE. The database runs in a container the agent pulls at instance creation. Unlike upstream, the ubuntu user has no password: access is by SSH key only. Trove boots it, tenants never do.
