Proxmox 4.0 Beta 1 is Now Available

proxmox logo gradThe latest release of Proxmox VE has entered it’s first BETA today with the release of Proxmox VE 4.0 BETA 1.

It’s the first public release of version 4.0 and comes with some pretty big changes!

HA Clusters are now configured using the Proxmox Web GUI and don’t require separate fencing kit – it’s provided out of the box. It’s about time, in my opinion, as plenty of other software manages HA without 3rd party processes to tell you what’s up and what’s down. This is a very welcome addition to any small Proxmox Cluster.

Linux Containers will replace OpenVZ as the Proxmox VE container solution. As you’d expect, LXCs will work with the usual Storage plugins offered by Proxmox, although Sheepdog, Ceph, iSCSI, DRBD and GlusterFS will be in a future release.

There are some other updates, such as the latest DRBD9 packages are shipped, and the whole thing runs on the latest Debian release, Debian Jessie 8.1.

You can download the ISO from their download site and install it onto a new machine. Unfortunately, because it’s still a BETA product there is no upgrade path from 3.4. I’d expect this to change in the near future.

It’s worth noting, however, that the website states that any BETA version of release 4.0 will be upgradeable to the full 4.0 when it’s available.

New features in Proxmox Test Repository

Category : Tech News

Get Social!

proxmox logo gradProxmox uses two main repositories (if you exclude the Enterprise repository) to release updates to Proxmox servers around the world. The usual repository pve-no-subscription is used to release updates for the Proxmox VE platform that are usually stable and tested. The other repository is the pvetest repository that contains new code that has not yet been thoroughly tested by the community. Updates in the pvetest repository should never be used in production, but are a great way to give something back to the Proxmox community by testing the code in a development environment and to see what new features are up and coming.

Martin Maurer sent an email to the Proxmox mailing list stating that a rift of changes and new features have been released to the pvetest repository and are available for download.

If you would like to use the pvetest repository on your Proxmox installation you will need to add the test repository source to your configuration. Remember, this is not recommended for production servers.

The notable features include:

  • A new Proxmox VE Firewall for the host and guests.
  • A new non-Java Html5 Console
  • Two-factor authentication

Keep an eye out for the official release, but we can speculate that a new version of Proxmox is just on the horizon containing these new updates.

proxmox logo gradProxmox has today released a new version of Proxmox VE, Proxmox 3.2 which is available as either a downloadable ISO or from the Proxmox repository.

Hilights of this release include’;

  • Ceph has now been integrated to the Proxmox web GUI as well as a new CLI command created for creating Ceph clusters. See my post on Ceph storage in Proxmox for more information.
  • SPICE is now fully integrated as the console viewer however the original Java console is still the default. SPICE supports multiple monitors and all recent guest operating systems.
  • QEMU has been updated with better backups and a few new supported guest hardware devices, mostly for compatibility with VMWare.

You can download the ISO from Proxmox directly at the following link:

If you already have Proxmox installed, you can use the below commands to automatically update your Proxmox servers to the latest 3.2 version from the terminal. Before updating, make sure all your VM’s have been stopped. Run the below commands on each server in your cluster.

apt-get update
apt-get dist-upgrade

Restart all Proxmox servers to complete the installation.

proxmox logo grad

New updates to Proxmox 3.1 have been released which can be applied using apt-get.

The main feature in this suite of updates is that the Java VNC console is now signed which should result in far fewer annoying messages when starting the console. There are a few other updates, including bug fixes and support for iSCSI targets (istgt) on ZFS.

Run the update and upgrade command to apply the recent updates. There is no need to shut down any running guests or restart your host with this update.

Proxmox 3.1 package/ updates manager

Get Social!

proxmox logo gradProxmox version 3.1 made a huge change to the way updates are managed. Prior to version 3.1, updates for the PVE software were managed from two main repositories – test and production – both of which were free and available. Generally the production repositories were used to ensure a stable and secure Proxmox host. These two repositories have now changed to the following:

Please note, this also works for version 4.x.

None subscription repository

This repository remains free, and all the code is still under AGPL v3. I believe this repository is similar to what the test repository used to be – containing test and potentially buggy packages. There is also the standard Debian repository for all other, non-Proxmox, updates. As these packages are potentially unstable, it is not recommended to use this repository for a production server.

Proxmox Version 3.x

Proxmox version 3.x is based on Debian Wheezy.

deb wheezy main contrib
deb wheezy pve-no-subscription
Proxmox Version 4.x

If you run version 4.x of Proxmox, based on Debian Jessie then you’ll need to adjust the URL slightly as below:

deb jessie main contrib
deb jessie pve-no-subscription

Enterprise repository

This repository requires a subscription license key to be added to Proxmox before you can access it. These packages are stable and are recommended for any production Proxmox server after version 3.1.

If you do not have a valid subscription, you will need to remove this repository otherwise apt-get will never complete it’s update. Without a valid subscription, you will see errors such as “You do not have a valid subscription for this server. Please visit to get a list of available options.

Proxmox valid subscription error

Proxmox valid subscription error teminal

To remove the repository, open the source list file in the apt-get sources folder

vi /etc/apt/sources.list.d/pve-enterprise.list

And comment out the line with a # as below.

#deb wheezy pve-enterprise

All updates will now come from the none subscription repository which are publicly available. Unfortunately, each time you click the Refresh button on the Updates tab you will receive the above message. You will also receive this message when you login to the web GUI.

What about the old updates repository?

The original updates repository should be removed once you have upgraded to Proxmox 3.1. No future updates will be available in this repository.

Edit the sources list and comment out the old repository:

vi /etc/apt/sources.list

If you used the test repository, you will need to comment that out too.

# PVE packages provided by
#deb wheezy pve

How to remove the “No Valid Subscription” message

Each time you log into Proxmox 3.1 a dialogue box pops up reminding you that you have not purchased a valid subscription. One way to remove the message is to purchase a subscription from the Proxmox team. Another method is to make a slight change to the code to remove the dialogue box from appearing.

See my post on how to change the code to remove the dialogue box.

Proxmox 3.1 is now available!

Get Social!

proxmox logo gradA new release of Proxmox is now available, release 3.1.

The highlights of this new release are:

  • A new storage plugin for GlusterFS.

Proxmox storage typesThis is a new storage plugin which can be used to add usable storage to your Proxmox host. GlusterFS is an open source, distributed file system with potential to house a huge capacity of data.

GlusterFS is key to open source, scalable and highly available storage spanning many servers, and even data centres.

See their About page for more information:

  • The SPICE protocol has been implemented as a technology preview. Whilts it is not recommended for production systems, you can see what’s in store in the Proxmox roadmap.
  • One of the most dramatic changes of Proxmox 3.1 is that the package repositories have been split into subscription and none-subscription. The subscription repository is the only repository recommended for a production server, however it requires a paid subscription with Proxmox to access it. See this thread for more information on the new Updates GUI page.

Proxmox updates manager

You can update any 3.0 install of Proxmox to the latest 3.1. Before updating, make sure all your VM’s have been stopped. Run the below commands on each server in your cluster.

apt-get update
apt-get dist-upgrade

Restart all Proxmox servers to complete the update.
