Highlights

  • New major release based on the great Debian Trixie.
  • Seamless upgrade from Proxmox VE 8.4, see Upgrade from 8 to 9.
  • VM snapshots on thick-provisioned LVM storages with snapshots as volume chains (technology preview).A new property on thick-provisioned LVM storages enables support for snapshots as volume chains. With this setting, taking a VM snapshot persists the current virtual disk state under the snapshot's name and starts a new volume based on the snapshot. This enables VM snapshots on shared thick-provisioned LVM storages, as they are often used on LUNs provided by a storage box via iSCSI/Fibre Channel.
  • High-Availability (HA) rules for node and resource affinity. HÀ affinity rules are a new mechanism to control the placement of HA resources, such as HA-enabled VMs and containers, on nodes. Node affinity rules mandate that HA resources should only be placed on particular nodes. Resource affinity rules mandate that a particular set of HA resources should always stay together on the same node or spread out to different nodes.
  • Fabrics for the Software-Defined Networking (SDN) stack. Fabrics are routed networks of interconnected peers. The SDN stack now supports creating OpenFabric and OSPF fabrics of Proxmox VE nodes. Fabrics can be used for a full-mesh Ceph cluster or act as an underlay network for Virtual Private Networks (VPN).
  • Modernized mobile web interface. The mobile interface allows a quick overview over guests, tasks, storages, and other resources. It also allows basic maintenance tasks, such as starting and stopping virtual guests. The overhauled mobile interface is written in Rust and based on the Yew framework and the Proxmox Yew widget toolkit.
  • ZFS now supports adding new devices to existing RAIDZ pools with minimal downtime.
