FINALLY. Another big milestone for us.

XO 5.111 is out. And yes, the release notes are almost as long as September felt 😅

VMScape and why Xen dodged it ETH Zürich’s new VMScape attack hit KVM and VMware, but Xen’s microkernel-like design kept it out of reach.

2 weeks ago, ETH Zürich revealed VMScape, a new CPU side-channel attack.
KVM and VMware are affected, Xen isn’t.

Not because Xen is flawless, but because its microkernel-like design puts security first.

We reviewed the recent NPM supply chain attack: Xen Orchestra production users (XOA or from source) are not affected: only dev environments could be at risk if yarn.lock was ignored.

Great news for those relying on @veeam.com 🎉

If you’re part of the Veeam 100 Program, you can already test the brand-new XCP-ng plugin, bringing native compatibility between the Vates stack and Veeam products!

Cf the article. The only thing preventing us to sign is Microsoft taking ages to do it. We hope they will finally move forward!

Windows PV drivers: update and roadmap From downstream fixes to upstream collaboration, here's where we stand with Windows PV drivers. And where we're headed next!

We’re now upstream maintainers of the Windows PV drivers 🥳 It’s the result of months of work to improve things where it really matters.

Along the way, we found a vuln, one that led the biggest cloud provider to patch millions of VMs 🤯

That’s what involvement looks like!

Xen Orchestra 5.108 June’s XO 5.108 release is packed with major updates, reflecting our current focus areas: backups, REST API, UI evolution, and DevOps tooling.

Xen Orchestra 5.108 just landed. So far, likely the biggest release of the year! Tons of new endpoints for the REST API, Qcow2 backup, Azure Storage, many new views in XO 6 & XO Lite and so on. DevOps side is also well packed with a CCM for XO among other things.

Just after XCP-ng 8.3 became LTS, we kicked off the journey to 9.0. Things are getting real: we're moving from early exploration to a first concrete target.

XO 6.0 as the default UI + XCP-ng 9.0 pre-pre-pre-alpha in 2025?

Maybe 👀 Stay tuned!

Who owns your virtualization stack? In a world full of open-source wrappers and orchestration layers, who actually owns the foundation your infrastructure runs on?

Who owns your virtualization stack?

It’s not a feature list: just a point of view on what (I think) really matters post-VMware.

I did my best to keep it fair, even if I’m someone building one of the alternatives.

Let’s skip the tool tribalism please 🙏

XCP-ng 8.3 is now LTS Today, XCP-ng 8.3 becomes LTS, including new ISOs and XOSTOR officially available with it.

✅ XCP-ng 8.3 is now LTS!
– Long Term Support status
– XOSTOR now supported
– Refreshed ISOs with latest updates & security fixes

No new version to install if you're already on 8.3: just keep updating!

The right time for Europe In a world where resilience depends on more than supply chains, Europe must decide where it wants control—and where it’s willing to depend on others.

Europe doesn’t need to build everything. But it does need to stop outsourcing its future.

My thoughts after many many years in deep tech.

virtualize.sh/blog/the-rig...

Je pense que c'est toujours utile, à donner un angle/point de vue ou expérience que ne donneras pas un LLM. Pourquoi je préfère ci ou ça par rapport à mon expérience, le contextualiser dans un besoin existant etc.

Luckily, it's only a minority. But yeah, at this scale and done this way, it is remarkable 😆

Hypervisors and low-level network plumbing are still one of my passions. New IT employee pro tip: learn low-level #SysAdmin, #kernel dev, and #networking. The AI datacenters don't run on vibe code kids... 😏

You can’t Git clone a team Mastering the full stack isn’t just a technical feat: it’s a human challenge, and no, you can’t git clone your way out of it.

Building a full stack (from hypervisor to orchestration) is already a huge challenge.

But what about building the knowledge and the team behind it?

You can't just "git clone" expertise, experience, and trust.

Really happy with how this collaboration came together: it all started with a shared customer request and quickly turned into a perfect match with our existing solutions.

Exciting stuff, and definitely more to come in this space!

The Open Source we use at Vates: 2025 edition How do you scale from 3 to 100 people while staying fully self-hosted and open source? Here's our 2025 update on the tools we use, to prove it’s not just possible, it’s powerful.

Can you scale a company to more than 100 people while staying fully self-hosted and using only open source tools?

Pourtant je suis resté factuel 😄

Few build Hypervisors. We’re one of them. Everyone uses virtualization. Few truly understand what they’re building on. That’s why calling hypervisors a commodity is a dangerous illusion.

I thought it was time to share some perspective on what it takes to build a full virtualization stack.

We’ve learned a lot over the years, often the hard way. Using a platform is one thing. Building and maintaining it is something else entirely.

I'm incredibly proud of what the team has accomplished with this XO release 🤩

A huge thanks to everyone involved: your hard work and dedication are really paying off. It’s amazing to see how much our team has ramped up, delivering such an impressive release in just one month.

Take a guess on what it shows! (still early but "it's alive!"). Answer in ALT 😀

Please stop planting only corn A blog post in defense of digital biodiversity

Monoculture in IT is a trap. It looks simple at first, but leads to lock-in, pricing shocks, and even geopolitical risks. From IE to VMware, we’ve seen it. Diversity isn’t harder—it’s smarter. I wrote about it here 👇

A host Dashboard view is landing this month — and it’s not the only new thing coming! 😉

Really happy to see our DevOps team getting full steam ahead!
