The new beta release of the popular virtualization environment based on Debian 13 “Trixie” is now available for download. It features significant improvements in networking, storage, and Ceph.
The Proxmox development team has announced the launch of the beta version of Proxmox Virtual Environment 9.0 (Proxmox VE 9.0). This next generation of their open-source virtualization platform is based on Debian 13 “Trixie” and includes a modern Linux kernel 6.14.8-1, along with key updates in virtualization, storage, and networking.
Although it is a testing version, it can already be downloaded from official repositories for testing and installation. However, developers recommend not using this beta in production environments and advise backing up before any updates.
Highlights of Proxmox VE 9.0 Beta
Some of the main improvements and new features include:
- Ceph Squid 19.2 as the default version, with extended support for distributed storage clusters.
- Software-defined networks (SDN Fabrics) for advanced architectures like two-layer spine-leaf or full-mesh Ceph configurations.
- Snapshots for shared LVM thick-provisioned volumes, compatible with iSCSI and Fibre Channel connections in SAN cabinets.
- ZFS 2.3, introducing RAID-Z expansion, for more flexible storage management.
- Multiple improvements to the graphical user interface (GUI) and API, simplifying management and automation.
- Overall performance and stability enhancements based on community feedback.
Requirements and Compatibility
The beta version is intended for developers, testers, and administrators eager to evaluate new features. It can:
- Be installed directly on Debian 13 “Trixie”
- Be upgraded from Proxmox VE 8.4, following a specific path that involves updating Ceph Reef to Squid before migrating to Proxmox 9
- Be upgraded from the beta to the stable release once it is published, through the
aptchannels
