Proxmox VE 4.3 released


VIENNA, Austria – September 27, 2016 – Proxmox Server Solutions GmbH today announced the general availability of Proxmox Virtual Environment 4.3. The hyper-converged open source server virtualization solution enables users to create and manage LXC containers and KVM virtual machines on the same host, and makes it easy to set up highly available clusters as well as to manage network and storage via an integrated web-based management interface.

The new version of Proxmox VE 4.3 comes with a completely new comprehensive reference documentation. The new docu framework allows a global as well as contextual help function. Proxmox users can access and download the technical documentation via the central help-button (available in various formats like html, pdf and epub). A main asset of the new documentation is that it is always version specific to the current user’s software version. Opposed to the global help, the contextual help-button shows the user the documentation part he currently needs.

The new reference documentation is created like the former Proxmox technical documentaion: manpages are autogenerated based on the code, help content itself is written by the developers via comments in the code. Then for generating the docu the Proxmox VE project uses asciiDoc. To participate in the documentation project users can send a patch to the open source projet for proposing new content. The former documentation, the Proxmox VE wiki, stays public, links to the reference documentation, and hosts all the howtos, use cases, etc.

The updated vertical GUI structure is one of the main advancements made to the GUI of Proxmox VE 4.3. Proxmox developers re-arranged some of the horizontal menus in the GUI framework Sencha ext JS 6 introduced with Proxmox version 4.2 and they are now vertical. This structure alsoallowed the Proxmox developers to build groups, add icons, and optimize the logical navigation structure. The flat design of the sencha theme made this step essential as menus weren’t very well recognizable. The vertical structure now shows every menu in a single line.

In the newly added groups content is unfolded and displayed by default. The same menus as in the old structure are shown. Users can choose to fold or unfold groups. For minimal supported displays the new vertical structure now provides more space in total.

More new features in the GUI:

  • New status overview for host, VM, container and storage.
  • Signal colors have been added and show for example when capacity of a CPU is used.
  • Diskmanagment: new disk overview, including S.M.A.R.T., and wearout for enterprise SSDs. Diskmanagement is new to the GUI; it used to be only accesible via Ceph and command line.
  • Defaults for VM creation: The wizard “Create VM” now proposes optimal settings dependent to the selected Linux-based operating system. For example, the default for Linux is “virtio scsi disk”.
  • Open console with double-click on VM or container (allow popups first)
  • Search function in the GUI (“ctrl-shift-f”)
  • “Task log”-window remembers its window size
