Proxmox VE 6.2 released


VIENNA, Austria – May 12, 2020 – Proxmox Server Solutions GmbH today announced the general availability of Proxmox VE 6.2, the latest version of the open-source virtualization management platform. Proxmox VE 6.2 includes new features aimed at addressing issues facing modern datacenter administrators and IT teams. The new version of the virtualization management solution comes with a lot of new features, notable improvements, and many advanced options for the web-based user interface. It's based on Debian Buster 10.4 and a 5.4 longterm Linux kernel and includes updates to the latest versions of the leading open-source virtualization technologies QEMU 5.0, LXC 4.0, Ceph Nautilus (14.2.9), and ZFS 0.8.3.

Highlights of Proxmox VE 6.2

Advanced options for the web-based management interface

  • Proxmox VE implements built-in validation of domains for Let's Encrypt TLS certificates via the DNS-based challenge mechanism, in addition to the already existing HTTP-based validation mode.
  • Full support for up to eight corosync network links is available. The more links are used, the higher the cluster availability.
  • In the storage content view, administrators can now filter the stored data with the new column ‘Creation Date’ which, for example, simplifies to search for a backup from a certain date.
  • The language of the web interface can be seamlessly changed without the need to restart the session. An Arabic translation has been added and thus Proxmox VE supports 20 languages in total.

Linux Container

  • The integrated container technology has been updated to LXC 4.0.2 and lxcfs 4.0.3. Proxmox VE 6.2 now allows to create templates for containers on directory-based storage.
  • New LXC templates for Ubuntu 20.04, Fedora 32, CentOS 8.1, Alpine Linux and Arch Linux.

Zstandard for Backup/Restore

  • The integrated backup manager supports the fast and highly efficient lossless data compression algorithm Zstandard (zstd).

User and permission management

  • Proxmox VE uses a role-based user and permission management for all objects such as VMs, storage, nodes, etc. The new LDAP sync enables synchronization of LDAP users and groups into the Proxmox user and group permission framework.
  • Full support and the integration for API tokens has been added allowing stateless access to most parts of the REST API by another system, software or API client. API Tokens can be generated for individual users and can optionally be configured with separate permissions and expiration dates to limit the scope and duration of the access. Should the API token get compromised it can be revoked without having to disable the user itself.

Further notable enhancements

  • QEMU/KVM: Support for Live Migration with replicated disks (storage replication with zfs) is enabled.
  • Testing the Ceph storage has become easier as the uninstall process has been simplified.
