The long-awaited version Proxmox Virtual Environment 9.0 is now available, marking a significant leap in its tFull transition to Debian 13 “Trixie” and the incorporation of the Linux 6.14 kernel.
This update not only brings improvements in performance and compatibility, but also redefines the management experience for both system administrators and corporate environments.
Main new features of Proxmox VE 9.0
With this new version, Proxmox VE 9.0 is based on a refreshed foundation that includes QEMU 10.0.2, LXC 6.0.4, OpenZFS 2.3.3, and Ceph Squid 19.2.3This ensures optimized support for virtualization, containers, and distributed storage, as well as increased stability in critical environments.
Uno of the most visible changes is incorporation of a web interface specifically designed for mobile devices, developed in Rust with the Yew framework. This new GUI It is automatically activated when accessed from a smartphone or tablet, providing a clear view of the status of virtual machines, tasks, storage, and resources. It also allows you to perform basic actions such as starting or stopping VMs, adjusting settings, and maintaining control even when away from the office.
More flexible and universal snapshots
Proxmox VE 9.0 introduces an improved system for creating snapshots in block-based storage, compatible with technologies such as iSCSI and Fibre Channel. The novelty lies in the use of volume chains, where Each snapshot stores only the changes relative to the primary diskThis functionality also extends to directory, NFS, and CIFS storage, increasing backup and recovery options.
Another of the new features presented in this new version of Proxmox VE 9.0 is the New HA affinity rules feature allows you to precisely control the placement of virtual machines and containers within a cluster. Now It is possible to group resources that depend on each other, such as an application server and its database on the same node to optimize latency, or distribute critical instances across different nodes to ensure fault tolerance.
SDN Fabric: Software-Defined Networking Made Easy
The Software-Defined Networking Stack now includes SDN Fabric, A tool that simplifies the creation and management of routed networks between nodesCompatible with OpenFabric and OSPF, this system is ideal for setting up Ceph clusters or VPN backbones, automatically managing routes and network card failures.
In addition to this, one of the most valued points is the Ability to migrate from Proxmox VE 8.x to 9.0 seamlessly, without downtime. This facilitates the adoption of the new version in production environments.
In the storage section, OpenZFS now allows adding disks to a RAID array. existing pool without having to recreate the pool or interrupt service. The system automatically redistributes data, optimizing available capacity.
Additional changes and optimizations
In addition to the major new features, Proxmox VE 9.0 incorporates improvements to its web interface, notification management, virtual machine performance, and container management. These include:
- Improved translation handling and support for new languages, including Czech and Arabic.
- Live migration with optional network connection status transfer (conntrack).
- LXC containers are now unprivileged by default, strengthening security.
- More detailed metrics for CPU, memory, and I/O usage, with greater granularity in historical charts.
- HA affinity rules are a new mechanism for controlling the placement of HA resources, such as HA-enabled virtual machines and containers, on nodes.
Node affinity rules require that HA resources be placed only on specific nodes.
Resource affinity rules require that a particular set of high availability (HA) resources always remain together on the same node or distributed across different nodes. - Increased the memory allocated to the virtual machine for single file restore.
- Fixed an issue where restoring a container backup from Proxmox Backup Server would fail if the backup contained a hard link.
