Proxmox VE (Virtual Environment) 3.3 Released
Proxmox Server Solutions GmbH, developer of the open source server virtualization solution Proxmox Virtual Environment (VE), today released version 3.3. The series of new features focus on security and include the Proxmox VE Firewall and two-factor authentication. A HTML5 console, the ZFS storage plugin and the Proxmox VE Mobile touch interface extend the range of use. Many package updates are included in the release.

Highlight of the new release is the Proxmox VE Firewall. It has a distributed nature and is designed to protect the whole IT infrastructure. Completely integrated into the web-GUI and the cluster stack, it allows the user to setup firewall rules for all hosts, the cluster, virtual machines and containers. To keep these tasks simple, the Proxmox VE Firewall comes with features like firewall macros, security groups, IP sets and aliases. While configuration is stored on the cluster file system layer, the iptables run on each cluster node providing full isolation between individual virtual machines. In contrast to a central firewall solution, the distributed nature of the Proxmox VE Firewall provides a higher bandwidth, and at the same time avoids bottlenecks.

The newly integrated two-factor authentication will add an extra layer of security to Proxmox VE. With version 3.3, login with a one-time password (OTP) can be enabled to the username/password interface login – this works for all authentication realms, including LDAP or Active Directory. The Proxmox developers offer two different methods: YubiKey from Yubico and Time Based One-Time Passwords (with OATH). These secure login processes shall help to prevent unauthorized persons or programs to access the virtualization servers.

The new HTML5 console (noVNC) is set as the default in Proxmox VE 3.3. It works on every platform (Windows/Linux/OSX), even on mobile devices and supersedes the installation of the Java plugin or SPICE viewer.

In addition to the full featured web interface, Proxmox VE Mobile is a touch interface designed specifically for the use on mobile devices (phones and tablets). It is just a HTML5 app built with Sencha Touch and it runs on any mobile with a modern browser. Proxmox VE Mobile includes a lot of key functionalities needed to manage virtualization on the go, including the HTML5 and the SPICE console. It is meant as an additional help for the admin, but not to replace the full admin interface. Proxmox VE Mobile also supports two-factor authentication like a YubiKey with NFC.
