Proxmox VE 9.0 Released with Major Networking, Storage, and Mobility Upgrades
Proxmox Virtual Environment (Proxmox VE) 9.0 was officially released on August 5, 2025, introducing a series of important improvements for server and data center administrators. Based on Debian 13 “Trixie” and running the Linux kernel 6.14.8-2, the new version delivers significant advances in performance, security, and flexibility.

- SDN Fabrics: build complex topologies such as spine-leaf with OpenFabric and OSPF support.
- New HA affinity rules: greater control over VM and container distribution across high-availability clusters.
- Revamped mobile interface: now powered by Rust + Yew for a smoother mobile browser experience.
- General improvements in security, performance, and hardware compatibility.
