Proxmox Server Solutions GmbH has released Proxmox Virtual Environment 8.0, a server virtualization management platform. This major release is based on Debian 12 and offers a smooth upgrade path for users of Proxmox VE 7.4 or older versions. Proxmox VE 8.0 incorporates several updates, including a newer Linux kernel (version 6.2), and the latest versions of QEMU, LXC, ZFS, and Ceph Quincy.
Key highlights of Proxmox Virtual Environment 8.0 include:
1. Ceph Enterprise repository integration: Proxmox VE now fully integrates Ceph Quincy, enabling the management of Ceph storage directly from any cluster node. This simplifies the setup and management of a hyper-converged infrastructure.
2. Authentication realm sync jobs: Users and groups can be automatically synchronized for LDAP-based realms, such as LDAP and Microsoft Active Directory. This feature reduces configuration errors and simplifies management.
3. Network resource management: Software-defined Networking (SDN) resources can be defined as objects in the access control subsystem (ACL). This allows fine-grained permissions for host network bridges and VNets, granting specific users and groups access to them.
4. Resource mappings: Mappings between resources (e.g., PCI(e) or USB devices) and nodes in a Proxmox VE cluster can be created and managed through the API and web interface. This enables offline migrations for virtual machines (VMs) with passed-through devices, enhancing flexibility.
5. Secure lockout for Two-factor authentication/TOTP: User accounts with excessive failed login attempts for the second factor authentication are locked out for one hour. This protects against brute-force attacks. Recovery keys or manual administrator intervention can unlock the accounts.
6. Text-based user interface (TUI) for the installer ISO: A new text-based user interface option is available during installation, which helps address compatibility issues on newer and older hardware.
7. Default CPU type: The x86-64-v2-AES model is set as the default CPU type for VMs created via the web interface. It offers additional features and improves performance compared to qemu64/kvm64.
