Time to share more on XO 6: why we built it, what’s improved, and what’s next. It’s already 13x faster on 1000x VMs setups, with a new API-first core and a UI designed to feel familiar for VMware users. We built it for scale and it delivers! xen-orchestra.com/blog/inside-th…

A VM booted today. On a fresh Dom0. Kernel 6.12. AlmaLinux 10. Toolstack alive. All very raw. Very early. Not for the public. Not yet. But for us… it’s a spark. XCP-ng 9.0 is waking up. ⚡👶

June’s release is a big one. Honestly amazed at how much the team pulled off in just a month. I guess that’s what happens when you keep growing with the right people onboard. 👏

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-owns-…

OlivierLamber12's tweet card. In a world full of open-source wrappers and orchestration layers, who actually owns the foundation your infrastructure runs on?

$130M company. 4000 VMs. 60+ trial accounts. Zero shame. (Also: our software is open source.) 👇 virtualize.sh/blog/ground-co…

OlivierLamber12's tweet card. When a $130M aerospace company chooses to endlessly abuse free trials instead of typing git pull, you start to question gravity, or at least common sense.

What if your virtualization platform didn’t just claim transparency… but lived it? At Xen, our CI is public. Every test run, every platform. You can even add your own hardware. It’s 𝒄𝒐𝒍𝒍𝒂𝒃𝒐𝒓𝒂𝒕𝒊𝒐𝒏 𝒂𝒕 𝒕𝒉𝒆 𝒉𝒂𝒓𝒅𝒘𝒂𝒓𝒆 𝒍𝒆𝒗𝒆𝒍. #XenProject #CI #OpenSource

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-cant-…

OlivierLamber12's tweet card. 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.

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!

We’re excited to partner with @EasyVirt to bring capacity planning, infrastructure insights, and sustainable IT to XCP-ng/XO users — including energy & CO₂ impact analysis across your entire stack! 🌱📊 vates.tech/blog/vates-eas…

Really proud of this one. Thanks to @CloudTemple for their trust and to both our teams for making it happen so quickly. Also a great moment to see two French companies working together at this scale, breaking the old "no prophet in his own country" curse!

VVates@vatesfr · Apr 26

Our stack can power existing public or hybrid clouds as a core engine, just like in our partnership with @CloudTemple. A natural fit, offering a real alternative to VMware! Article (in French): lemondeinformatique.fr/les-dossiers/l…

We’ve been working on a new backup engine for Xen Orchestra: designed for more formats, larger disks, and a cleaner, modern architecture. It’s already being tested in the wild... curious? 👀 Your feedback could help us ship it even faster! xen-orchestra.com/blog/next-gen-…

They said you can’t run a company on open source. They said you can’t scale it either. Well, we’ve done both. Here’s a look at the tools we use to make it happen. If we did it, you can too!

VVates@vatesfr · Apr 23

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-open-…
