Been waiting for this one. Full k8s lifecycle on your own infrastructure, no proprietary control plane. CAPI is still a demonstrator but the direction is set. Regarding backups, you can now actually and easily test your recovery plan thanks to bidirectional incremental replication 🤩

New XO release day and I'm a bit dizzy honestly, feels like 6.3 was barely 2 weeks ago. Months go by fast when the team is shipping at this pace.

Wild to think this started as a side project 15 years ago. Today @vates.bsky.social ships Kubernetes CCM 1.0 + CSI updated, MCP for AI capabilities, and a rewritten immutability engine (30x faster, 7x less memory), all in a single month. Proud of this team. 🚀

Kudos to our community and our team to maintain such momentum 🚀

Lundi nous accueillerons Nathanael Hannebert (de Vates) qui nous parlera de XCP-ng (une totale découverte pour nous). Installation, ecosystem, automatisation... nous aborderons ces sujets avec vous ! Ça se passera lundi à 21h sur CuistOps ( twitch.tv/CuistOps ) !

#FOSDEM 26: come to see our team on the XCP-ng/Xen Orchestra booth! Check our free shiny stickers 🥳

Xen Orchestra 6.1 is now available! Many improvements, both in terms of UI, REST API but also for our devops tools: Packer/Terraform providers, an official doc for Talos and much more. It's also the opportunity to announce our tech partnership with Pure Storage! xen-orchestra.com/blog/xen-orc...

As you can see, it’s been a very busy year. These major releases are laying down the foundations for 2026 and beyond. Still a bit amazed that we managed to build all of this in 2025. Now I understand why it felt so intense 😂

Xen Orchestra 5.112 is out! 🎃 Mirror backup sync merge, new XO 6 views, big REST API milestone, Lenovo IPMI, NetBox 4.4 support… And more! Plus a recap of our recent announcements: @veeam.com beta for XCP-ng, signed Windows drivers & large disk support! xen-orchestra.com/blog/xen-orc...

FINALLY. Another big milestone for us.

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

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. virtualize.sh/blog/vmscape...

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. More details at: docs.vates.tech/security/adv...

🛰️ XO 5.110 is here! 10–20x faster VMware migrations ⚡ VEEAM closed beta with native XCP-ng ✅ First redesigned backup UI in XO 6 🎨 …and plenty more improvements! xen-orchestra.com/blog/xen-orc...

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!

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! xcp-ng.org/blog/2025/07...

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. xen-orchestra.com/blog/xen-orc...

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? 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 🙏 virtualize.sh/blog/who-own...

✅ 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! xcp-ng.org/blog/2025/06...

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...

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... 😏

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. virtualize.sh/blog/you-can...

Xen Orchestra 5.106 is out! Packed with features: ✅ MicroK8s-powered Pyrgos ✅ MS Teams notifications ✅ Audit log continuity ✅ REST API & UI upgrades ✅ Better VMware → Vates migration …and more! xen-orchestra.com/blog/xen-orc...

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!

Can you scale a company to more than 100 people while staying fully self-hosted and using only open source tools? Check out our updated 2025 stack: what we use, what we replaced, and what’s next! vates.tech/blog/the-ope...

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. virtualize.sh/blog/few-bui...

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 😀

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 👇 virtualize.sh/blog/please-...

Ça y est, je me suis enfin construit un homelab 🖥️ 🧪 digne de ce nom à l'aide d'un rack 10". Je vous raconte ça dans un billet de blog, avec de vrais morceaux de @vates.bsky.social dedans ! 😊 rodolphe.breard.tf/article/cons...

Want to contribute to open source without writing code? Join the community, help others, or translate! About translation, we now use Weblate (100% open source & self-hosted in a VM on XCP-ng) to translate XO Lite & XO 6. Jump in and contribute! translate.vates.tech/engage/xen-o...

While our DevOps team keeps adding integrations, the XO 6 / XO Lite frontend team is pushing the new UI forward. 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!

The DevOps Tools team is now adding even more firepower to our already packed monthly feature releases! 🚀🔥 Exciting times ahead! 🤩

🐹The Vates DevOps Tools team is proud to announce the release of the first version of a @golang.org SDK that provides a client for using of the JSON-RPC XO API! 🎉 Contributions are open and welcome! github.com/vatesfr/xeno...

On a personal note, this was the first Xen Project event we fully organized ourselves. We learned a lot along the way! It was a true team effort, so kudos to all the attendees and my fantastic team for making it a reality, and a GREAT success! 🤩

Xen Orchestra 5.103 is now available. That's our first release for 2025, and it's already packed with many exciting announcements. Take a look: xen-orchestra.com/blog/xen-orc...

Organizing this has been a challenge, and I'll feel a huge relief once it’s over. But right now, I'm incredibly proud of what we've built for the Xen project, the engine behind the Vates stack. A sold-out event, global contributors, and a thriving community: this is what open source is all about!

XO 5.102 is here! 🛰️ Wrapping up 2024 with a bang: new features like sync merge, selective backup health check, scheduled RPUs, and more. Plus, a recap of an impressive year in features, code, and community growth. 👉 Don’t miss the announcement: xen-orchestra.com/blog/xen-orc...

Xen Orchestra 5.101 just landed. And it's BIG 🛰️ Long term backup retention via GFS, vTPM restore, CloudBase Init among many other new stuff. Details in here: xen-orchestra.com/blog/xen-orc...

🚀 XAPI: OCaml Powering the Cloud Since 2007 ☁️ Did you know? XAPI, the core of XenServer and XCP-ng, has been written in OCaml since its XenSource days (pre-2007!). Used by Citrix and Vates, it’s an open-source, industry-proven alternative to VMware. 👉 github.com/xapi-project... #ocaml #cloud

Just finished migrating our company's VM stack away from VMware and onto XCP-NG. There's pluses and minuses. Some parts of XCP-NG are easier and more straightforward (especially updating), some are more complicated. Overall, do recommend, especially given Broadcom's predatory licensing changes.

🚀 New services coming soon at Vates! We’re going beyond traditional support to help you build or migrate your IT infrastructure, meeting the needs of our growing customer base. Check out how we’re raising the bar on expertise and care. vates.tech/blog/expandi...
