Proxmox VE 9.2 Is Here: What’s New in This Release?
Proxmox VE 9.2 has been announced by Proxmox! What new features have been added to this open source virtualization platform? Find out in this article.
First of all, note that Proxmox VE 9.2 is based on Debian Trixie 13.5, and more importantly, this release is built on Linux kernel 7.0. Several important packages have also been updated: QEMU 11.0, LXC 7.0, ZFS 2.4, Ceph Squid 19.2.3 and Ceph Tentacle 20.2.1.

Cluster: Dynamic Load Balancer
The main new feature in Proxmox VE 9.2 is the addition of the Dynamic Load Balancer, a dynamic load balancer that is added directly to the cluster resource scheduler (a component called Cluster Resource Scheduler). Instead of relying on static metrics, it uses real-time resource usage (from nodes and guest machines) to determine where a resource should run (on which node) at a given t.
In addition, Proxmox says this new built-in load balancer can automatically migrate virtual machines managed by the HA stack to reduce imbalances between nodes. HA behavior and sensitivity can be adjusted through dedicated settings.
For cluster maintenance, Proxmox says it has added two commands to "arm" or "disarm" high availability (HA) at cluster level: disarm-ha and arm-ha.
What's new in SDN networking
The SDN layer in Proxmox VE gets several improvements in version 9.2, including the following:
- Native support for WireGuard and BGP,
- BGP/EVPN filtering based on route maps and prefix lists,
- OSPF route redistribution for fabrics,
- Enhanced configuration options for the EVPN controller,
- Support for IPv6 underlay for EVPN.
Managing custom CPU models
A new section has been added to the Proxmox administration interface, available here: Datacenter > Guest Resources/Hardware. It lets you create, edit, and delete custom CPU models directly from your browser. A CPU flag selector for VMs shows the flags supported on each cluster node (which can help avoid compatibility issues...).
As a reminder, custom CPU models make it possible to precisely tailor the virtual processor exposed to virtual machines based on a specific set of features.
Windows 2023 certificates: a modernized EFI enrollment process
Another improvement concerns Windows environments, especially the Microsoft and Windows 2023 certificate enrollment process. This ties in with the new Secure Boot certificates, namely Windows UEFI CA 2023 and Microsoft KEK CA 2023.
Proxmox highlights the following improvements:
- Beyond the command line: in addition to using the CLI command
qm enroll-efi-keys, the enrollment process can now be completed entirely through the web interface and API. - Proactive alerts: when a VM starts, users are now warned if Microsoft certificate enrollment is missing for EFI disks.
To learn more, I invite you to check the full changelog on the Proxmox website. Proxmox VE 9.2 is now available as an ISO image on the official website (see this page). If you already have a Proxmox VE server, the update is available through the APT package manager.
