XO 6.10: paste into consoles, 3x faster backups

Hello everyone, 🎃

XO 6.10 finally brings one of our most requested features: you can now paste text into host and VM consoles, in XO 6 and XO Lite. Backups get faster, with full mirror backups up to 1.4 GB/s on our test bench, and live restore boots a VM straight from its backup. XO 6 takes over more of backup management, and the load balancer can now pin VMs to hosts.

Please plan this update: XOA and XO Proxy move to Node.js 22.23.4, which fixes a high-severity vulnerability. Our funding round, the new Vates Alliance Network platform and our November events, KubeCon included, are below. Enjoy!

🛡️ Security

⚠️ XOA and XO Proxy now run Node.js 22.23.4, which fixes CVE-2026-111497, a high-severity flaw in the Brotli decoder. Before updating, check that your XOA can reach nodejs.org (XOA > Support). If you run XO from sources, update Node.js yourself.

💾 Backup Pro

Full mirror backups go from 450 MB/s to 1.4 GB/s on our test bench, and incremental backups can skip NBD encryption on an isolated backup network.

⏪ Live restore Pro Preview

Last month's live mount becomes live restore: a VM boots straight from its backup, without restoring its disks first. Its writes go to a local cache, so the backup stays untouched. Keep it away from critical production workloads for now.

🥝 Console clipboard Free

Paste text from your computer into host and VM consoles, in XO 6 and XO Lite, typed in your keyboard layout (AZERTY and QWERTY for now). Handy for long passwords when there's no SSH.

🛰️ XO 6 Free

Create, edit and bulk-edit backup repositories, list backup jobs and logs, and migrate VMs within or across pools. Changes now show up in real time, and you can export disks in VMDK.

🔭 XO Lite Free

A host side panel, host actions (detach, disable, enable, restart the toolstack) and PIFs you can forget from the network view.

⚖️ Load balancer Enterprise

VM-to-host affinity: tag VMs and hosts to keep those VMs on those hosts. Tagged VMs can now also move for performance, as long as their rules hold.

🐦 VMware to Vates (V2V) Free

Still on older VMware hosts? V2V reads disks from ESXi 6.x again, tested end to end on ESXi 6.0.

📡 REST API Free

Real-time updates over subscriptions (no more polling), plugin management, SR probe endpoints and priorities for SDN traffic rules.

☸️ DevOps tools Free

Our Cluster API provider went through five v1.1.0 release candidates (IPAM pool addresses, extra XO tags, Helm options), the Go SDK shipped v1.20.0 and v1.21.0, and the Cloud Controller Manager now handles VM shutdowns better.

🆕 And more

NetBox 4.7 support, a multipathing fix that keeps local SRs connected, the estimated VM power metric documented for OpenMetrics, and 12 more languages fully translated. Full details in the changelog, and you can watch our XO 6.10 overview video.

🔹A new home for the Xen Orchestra project

xen-orchestra.org has a new design, built around the open source project: five ways to run XO, the latest releases, and where the community lives.

🔹XCP-ng and Xen Orchestra on RISC-V

After Xen on real boards last month, Bruno ran the full stack in QEMU: XO starts VMs and opens consoles, and a Debian guest runs Docker and K3s. A prototype, and an honest progress report.

🔹Reading Intel CPU temperatures from dom0

Under Xen, dom0 can't read them on its own. Teddy explains how XCP-ng now does it with xenpm get-core-temp, without touching the security model.

Here's where to catch us next:
