An inside look at NixOA—a project that brings the full power of NixOS to running and maintaining Xen Orchestra.

In this session, Dale will walk through how NixOA uses the NixOS module system, upstream Vates code, and atomic upgrades to turn XO into a fully declarative, reproducible, and drift-free appliance.

He’ll cover how it builds XO and plugins from source, integrates the Rust-based Xen guest agent, supports NFS/SMB remotes, and can optionally generate TLS certificates automatically—all while staying cleanly extensible through custom services and packages. Check out how Nix can make Xen Orchestra easier to deploy, update, and operate at scale.
