Proxmox Day 2025

Review of the Dutch Proxmox Day 2025

On September 25, 2025, we attended the Dutch Proxmox Day 2025 in Ede (Netherlands) – and I must say: the event was a complete success. Organized by Tuxis B.V. at the Hotel Belmont in the Veluwe region, the day offered an excellent mix of expert presentations and valuable exchange.

Thanks to the Hosts

A heartfelt thank you to the Tuxis team: For the invitation as a speaker, for the trust placed in us, and for the perfect organization. Yes — this blog article is coming a bit late, but as they say: better late than never.

My Perspective as a Speaker

As a speaker, I had the pleasure of being part of an exciting program. At the same time, I was a participant: both at the same time – that’s what makes such days special. I would like to highlight a few presentations:

• Aaron Lauterer (Linux Software Developer at Proxmox Server Solutions) – “Let’s get technical with a Proxmox developer”: A look at upcoming features of Proxmox VE. The upcoming integration of OCI containers (aka Docker) is particularly exciting.
• Rob Turk (Senior Presales Systems Engineer at Veeam) – “Save the data”: Clearly shows that Proxmox has now arrived in the enterprise world.
• Mark Schouten (CTO at Tuxis) – “Cool stuff you can do with Proxmox”: Proxmox Backup Server in interaction with ZFS, how to make the whole thing more performant and what unexpected problems with SCSI and Western Digital have occurred, Mark Schouten told us about it
• Alexander Wirt – “Balancing workloads in Proxmox”: My own contribution with a focus on the project ProxLB of my esteemed colleague Florian Hoberg, which distributes virtual machines evenly across nodes, again shows the advantages and OSS and open interfaces. These make it easy to add missing functionality and thus compete with the industry giants.
• Robbe Van Herck (Support & Maintenance Engineer at International Polar Foundation) – “Proxmox on Antarctica”: Proxmox in extreme use – at the other end of the world and very far from everyday data center life. Robbe was able to show well that Proxmox also works in the most remote corners of the earth, the other challenges are more exciting here – such as hardware that is overwhelmed by the low temperatures.
• Han Wessels (Operations System Engineer at ESA) – “Challenged to run Proxmox out of this world”: Why Proxmox can also be operated on the ISS or in space – technology meets vision. Han vividly described the challenges that arise, such as the vibration during the launch of the carrier rocket or the radiation that significantly shortens the lifespan of storage.

I was able to take away many impulses – both technically and ideally. And I had good conversations that will certainly pay off further.

Networking & Exchange

The informal part was just as valuable as the program: during the breaks, at lunch or at the get-together in the afternoon, we made new contacts, gained interesting insights and met old acquaintances. It is precisely these moments that make a conference come alive.

Outlook

We are already looking forward to next year. When the Tuxis team calls again, we will be happy to be there again. Many thanks again to all those involved, all speakers and all participants – see you again. In between, this December there will be the first Open Source Virtualization Gathering at our company.
