Proxmox VE 9.0: Revolutionising Open-Source Virtualisation

Proxmox VE 9.0 Overview

Proxmox Virtual Environment (VE) 9.0 represents a significant milestone in open-source virtualisation technology, released on August 5, 2025. This major update brings a modernised core built upon Debian 13 "Trixie", ensuring a robust foundation for the platform with enhanced security, improved hardware support, and the latest package versions. As a Proxmox Silver Partner in Hong Kong and China, Octotech Consultant Ltd is proud to introduce this cutting-edge platform to our clients, offering expert implementation, consulting, and support services to help you leverage its full potential.

This release continues Proxmox's 20-year tradition of innovation in open-source server solutions, providing enterprises with a powerful alternative to proprietary virtualization platforms. With over 1.6 million hosts worldwide and translation into more than 31 languages, Proxmox VE has established itself as a leading virtualization platform that enables organizations of all sizes to build cost-effective, flexible software-defined data centers without vendor lock-in.

Key Features and Enhancements

Debian 13 "Trixie" Foundation and Updated Components

At the core of Proxmox VE 9.0 lies Debian 13 "Trixie", providing a stable and secure foundation for the entire virtualization platform. This update includes a newer Linux kernel 6.14.8-2, which enhances hardware compatibility and overall system performance. The platform also incorporates the latest versions of essential virtualization technologies:

  • QEMU 10.0.2 for advanced machine emulation and virtualization
  • LXC 6.0.4 for container management
  • ZFS 2.3.3 with support for adding new devices to existing RAIDZ pools with minimal downtime
  • Ceph Squid 19.2.3 for scalable storage solutions

These updates ensure that Proxmox VE 9.0 delivers improved performance, enhanced security, and better hardware support compared to previous versions.

Snapshots for Thick-Provisioned LVM Shared Storage

One of the most significant advancements in Proxmox VE 9.0 is the long-awaited support for snapshots on thick-provisioned LVM shared storage. This feature is particularly valuable for enterprise users with Fibre Channel (FC) or iSCSI SAN environments, as it enables:

  • Volume chain snapshots that only record differences to parent snapshot volumes
  • Enhanced storage management capabilities without relying on clustered file systems
  • Storage-independent snapshot solutions that work regardless of hardware vendor
  • Support for directory, NFS, and CIFS storages with similar snapshot functionality

This implementation provides a powerful solution for customers with traditional SAN infrastructure, closing the gap that previously existed in storage management capabilities.

New Fabrics Feature for Software-Defined Networking (SDN)

Proxmox VE 9.0 introduces a groundbreaking SDN Fabrics feature that simplifies the configuration and management of complex routed networks. This enhancement includes:

  • Support for multiple paths between nodes with automatic failover across Network Interface Cards (NICs)
  • Robust two-layer spine-leaf architectures for improved network redundancy and performance
  • Dynamic routing protocols including OpenFabric and OSPF support
  • Simplified management of dynamically routed networks suitable for Ethernet VPN (EVPN) underlay or full-mesh networks for Ceph

This feature enables administrators to construct highly complex and scalable network architectures with minimal effort, addressing critical enterprise networking demands.

Affinity Rules in High Availability (HA) Clusters

The new HA resource affinity rules in Proxmox VE 9.0 provide fine-grained control over resource placement in HA clusters, ensuring:

  • Optimal performance for critical workloads through precise VM placement control
  • Enhanced resiliency during HA failovers with strategic resource distribution
  • Minimized latency for interdependent applications by keeping related resources together
  • Maximum redundancy for mission-critical services by distributing instances across different nodes

Administrators can now precisely define how virtual machines and other HA resources are distributed across a cluster, significantly improving control over complex, interconnected applications

Enhanced Mobile Interface

The Proxmox VE mobile interface has undergone a comprehensive redesign using a Rust-based Yew framework, resulting in:

  • Improved mobile accessibility to essential management functions
  • Quick service overviews and basic configuration capabilities
  • Streamlined virtual guest management including starting and stopping operations
  • Modernized user experience that maintains functionality on mobile devices

This enhancement makes it easier than ever for administrators to manage their virtual environments directly from mobile browsers.
