VIENNA, Austria – November 23, 2023 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") today announced the release of version 8.1 of Proxmox Virtual Environment, its open-source server virtualization management platform. This version comes with several new features, support for Secure Boot, a Software-defined Network stack, a new flexible notification system, and many further enhancements and bug fixes.
Proxmox VE 8.1 is based on Debian 12.2 (“Bookworm”), but uses a newer Linux kernel 6.5 as stable default, and includes updates to the latest versions of leading open-source technologies for virtual environments like QEMU 8.1.2 and LXC 5.0.2. It comes with ZFS 2.2.0 including the most important bugfixes from 2.2.1 already. The virtualization platform adds support for Ceph Reef 18.2.0 and continues to support Ceph Quincy 17.2.7.
Highlights in Proxmox Virtual Environment 8.1
- Support for Secure Boot: This version is now compatible with Secure Boot. This security feature is designed to protect the boot process of a computer by ensuring that only software with a valid digital signature launches on a machine. Proxmox VE now includes a signed shim bootloader trusted by most hardware's UEFI implementations. This allows installing Proxmox VE in environments with Secure Boot active.
- Software-defined Network (SDN): With this version the core Software-defined Network (SDN) packages are installed by default. The SDN technology in Proxmox VE enables to create virtual zones and networks (VNets), which enables users to effectively manage and control complex networking configurations and multitenancy setups directly from the web interface at the datacenter level. Use cases for SDN range from an isolated private network on each individual node to complex overlay networks across multiple Proxmox VE clusters on different locations. The benefits result in a more responsive and adaptable network infrastructure that can scale according to business needs.
- New Flexible Notification System: This release introduces a new framework that uses a matcher-based approach to route notifications. It lets users designate different target types as recipients of notifications. Alongside the current local Postfix MTA, supported targets include Gotify servers or SMTP servers that require SMTP authentication. Notification matchers determine which targets will get notifications for particular events based on predetermined rules. The new notification system now enables greater flexibility, allowing for more granular definitions of when, where, and how notifications are sent.
- Support for Ceph Reef and Ceph Quincy: Proxmox Virtual Environment 8.1 adds support for Ceph Reef 18.2.0 and continues to support Ceph Quincy 17.2.7. The preferred Ceph version can be selected during the installation process. Ceph Reef brings better defaults improving performance and increased reading speed.
