We are proud to announce the release of the first beta of our Proxmox VE 4.x family - based on the great Debian Jessie.

Please help us reaching the final release date by testing this beta and by providing feedback.

A big Thank-you to our active community for all feedback, testing, bug reporting and patch submissions.

So what's new in Proxmox VE 4.0 beta1?

New Proxmox VE HA Manager for High Availability Clusters

The brand new HA manager dramatically simplifies HA setups – it works with a few clicks on the GUI, test it! And it elminates the need of external fencing devices, watchdog fencing is automatically configured.

Linux Containers (lxc)
The new container solution for Proxmox VE will be fully integrated into our frameworks, e.g. this includes also our storage plugins. And it works with all modern and latest Linux kernels.

We already included the brand new DRBD9 stable release, so its ready for testing!

New wiki articles and release notes

Alternate ISO download:


  • All beta1 installations can be updated to 4.0 stable without any problem
  • Currently there is no upgrade path from 3.4 to 4.0 beta1, the upgrade script will be provided later

Best regards,
