os-vif
A library for plugging and unplugging virtual interfaces in OpenStack.
Decision gist · record as of 2026-08-14
Yes, if you are operating or developing within OpenStack infrastructure. This is a foundational library for instance networking in OpenStack and is required by Nova. For non-OpenStack use cases, it has no relevance. No known security vulnerabilities as of the query date.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.11 or later; intended for use within OpenStack infrastructure, not standalone applications.
- Low install friction with a pure-Python wheel distribution.

What it is and what it does
os-vif is an OpenStack library that abstracts the mechanics of attaching and detaching virtual network interfaces to compute instances. It provides a plugin-based architecture (via stevedore) for different network backends and vNIC types, allowing Nova and other OpenStack services to manage instance networking without directly coupling to specific network implementations.
The library depends on the Oslo family of libraries (concurrency, config, logging, serialization, versioned objects) and ovsdbapp for database operations, making it a core component of OpenStack's networking infrastructure. It is maintained as part of the OpenStack project and targets modern Python versions (3.11–3.13).
Use it for
- Attaching and detaching vNICs when provisioning or terminating OpenStack compute instances
- Supporting multiple network backend implementations (OVS, Linux bridge, etc.) through a unified plugin interface
- Managing virtual interface state and metadata in OpenStack Nova compute service
- Enabling network configuration changes on running instances without service restart
