olivierlambert.bsky.social @olivierlambert.bsky.social · 06/10/2026If you had told me in 2012 that I'd write this one day, I would have laughed. From a Xen Orchestra side project to the Gartner Magic Quadrant (only French company ever) and a €30M round, still independent and open source. Thank you, Vatesians ❤️ 030
olivierlambert.bsky.social @olivierlambert.bsky.social · 28/05/2026Been 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 🤩 031
olivierlambert.bsky.social @olivierlambert.bsky.social · 29/04/2026New 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. 010
olivierlambert.bsky.social @olivierlambert.bsky.social · 31/03/2026Wild 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. 🚀 010

olivierlambert.bsky.social @olivierlambert.bsky.social · 13/04/2025I 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...virtualize.shFew 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. 144
