Proxmox Virtual Environment 8.0 with Debian 12 "Bookworm" released

VIENNA, Austria – June 22, 2023 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") today released the stable version 8.0 of its server virtualization management platform Proxmox Virtual Environment. This major release is based on the latest Debian 12 (“Bookworm), and comes with an extensively tested and detailed upgrade path for users of Proxmox VE 7.4 or older versions to enable a smooth upgrade. Proxmox VE 8.0 uses a newer Linux kernel 6.2 as stable default, and includes updates to the latest versions of leading open-source technologies for virtual environments like QEMU 8.0.2, LXC 5.0.2, ZFS 2.1.12, and Ceph Quincy 17.2.6.

The virtualization platform from Proxmox comes stocked with all the essential management tools and an easy-to-use, web-based user interface. This allows to conveniently manage individual hosts or the entire data center with out-of-the-box tools - either via a web browser or the command line.

Further highlights in Proxmox Virtual Environment 8.0

• New Ceph Enterprise repository: Proxmox Virtual Environment fully integrates Ceph Quincy, allowing to run and manage Ceph storage directly from any of the cluster nodes and to easily setup and manage a hyper-converged infrastructure. The Ceph source code is packaged by the Proxmox development team and—after extensive tests—delivered in the stable Enterprise repository. This unifies the delivery of Ceph with other components of Proxmox VE. With version 8.0, all Proxmox customers with an active subscription can now access the stable Ceph Enterprise repository recommended for production environments.
• Authentication realm sync jobs: The synchronization of users and groups for LDAP-based realms (LDAP & Microsoft Active Directory), can now be configured to run automatically at regular intervals. This simplifies management, and removes a source for configuration errors and omissions compared to synchronizing the realm manually.
• Network resources defined for Software-defined Networking (SDN) are now also available as objects in the access control subsystem (ACL) of Proxmox VE. It is possible to grant fine-grained permissions for host network bridges and VNets to specific users and groups.
• Resource mappings: Mappings between resources, such as PCI(e) or USB devices, and nodes in a Proxmox VE cluster, can now be created and managed in the API and the web interface. VM guests can get such an abstract resource assigned, which can be matched with concrete resources on each node. This enables offline migrations for VMs with passed-through devices. The mappings are also represented in the ACL system of Proxmox VE, allowing a user to be granted access to one or more specific devices, without requiring root access. In case a conflicting entry is detected, e.g. due to address changes or overlaps, users are informed on VM start.
• Secure lockout for Two-factor authentication/TOTP: To further improve security, user accounts with too many login attempts - failing the second factor authentication - are locked out. This protects against attacks where the user password is obtained and a brute-force guess is attempted on the second factor. If TFA fails too many times in a row, the user account is locked out for one hour. If TOTP failed too many times in a row, TOTP is disabled for the user account. The user account can be unlocked again with a recovery key, or manually by an administrator.
• Text-based user interface (TUI) for the installer ISO: A text-based user interface has been added and can now be used optionally to gather all required information. This eliminates issues when launching the GTK-based graphical installer that sometimes occur on very new as well as rather old hardware.
• The x86-64-v2-AES model is the new default CPU type for VMs created via the web interface. It provides important extra features over the qemu64/kvm64, and improves performance of many computing operations.
