This talk presents our approach to integrating OpenStack cloud infrastructure with NixOS, addressing a significant gap in development workflows for OpenStack Nova.

Our primary motivation was to simplify testing and development processes by leveraging NixOS' declarative and reproducible environment capabilities. We'll demonstrate how our implementation uses NixOS modules to create deterministic OpenStack deployments where components - particularly the Nova compute and the Neutron network service - are defined as NixOS modules within the Nix expression language. This approach eliminates configuration drift during development cycles and enables developers to quickly reproduce specific environments.

We'll share practical insights from our implementation journey, highlighting how this integration streamlines OpenStack development workflows through consistent test environments and easy service configuration manipulation. We'll discuss the qualitative improvements in developer experience and outline future directions for expanding NixOS support across the OpenStack ecosystem.
