Proxmox Virtual Environment 8.3, the latest enterprise virtualization solution, offers a range of management tools and a user-friendly web interface to facilitate the deployment of open-source solutions in clustered and highly available setups. Based on Debian 12.8 (Bookworm) with the Linux kernel 6.8.12-4 as the stable default, users also have the option to use kernel 6.11. This version includes updates to key open-source technologies for virtual environments such as QEMU 9.0.2, LXC 6.0.0, and ZFS 2.2.6 with compatibility patches for Kernel 6.11.
One of the key enhancements in Proxmox Virtual Environment 8.3 is the alignment of the Software-Defined Networking (SDN) stack with the firewall. This integration allows users to create virtual zones and networks (VNets) and effectively manage complex networking configurations and multitenancy setups directly through the web interface. The SDN stack now works seamlessly with the firewall to automatically generate IP sets for VNets and virtual guests, simplifying the creation and maintenance of firewall rules. Additionally, the opt-in firewall based on nftables can filter forwarded network traffic at both the host and VNet level, enabling more granular control over network traffic.
Another notable improvement is the addition of a webhook target for the notification system. This feature enhances the flexibility of the notification system by enabling users to trigger HTTP requests for various events such as system updates, cluster node issues, or backup jobs. With customizable request headers and body content, users can seamlessly integrate the notification system with any webhook-compatible service.
The introduction of the ‘Tag View’ functionality for the resource tree provides users with a quick and customizable overview of their virtual guests grouped according to assigned tags. This feature enhances the visibility and organization of virtual guests within the Proxmox Virtual Environment.
Proxmox Virtual Environment 8.3 also introduces support for Ceph Squid (technology preview), enabling users to select their preferred Ceph version during the installation process. Additionally, container backups to Proxmox Backup Server now complete faster, thanks to improved efficiency in detecting unchanged files since the last backup snapshot.
The developers at Proxmox have streamlined the process of migrating from other hypervisors, making it easier to import files in Open Virtualization Format (OVF) and Open Virtualization Appliances (OVA) directly from file-based storage via the web interface. This simplifies the guest import process and facilitates the migration of VMs from other hypervisors like VMware guests.
Tim Marx, COO of Proxmox, highlighted the significant growth of the open-source project Proxmox VE, with an increase of 300,000 active hosts in recent months, totaling around 1.3 million. With the evolving business landscape and new pricing shifts in the market, Proxmox is well-positioned for further growth and to better serve its customers.
