Efficient File Sharing with VirtioFS in OpenNebula

Managing storage across multiple VMs can be challenging, especially when several workloads require access to the same files. Duplicating large AI models, training datasets, and application data can quickly consume storage space and complicate management.

VirtioFS offers a more efficient way to share files between hosts and VMs without creating separate copies. With OpenNebula’s VirtioFS Datastore, you can register existing directories and make them available to VMs, opening up new possibilities for storage management and File System as a Service (FSaaS).

In this session, we’ll discuss how VirtioFS works, how to configure it in OpenNebula, and when to use it instead of traditional shared datastores.

What we’ll cover:

• VirtioFS overview: Understand how VirtioFS works and how it enables efficient file sharing between hosts and VMs.
• Configuration and considerations: Learn how to configure a VirtioFS Datastore in OpenNebula, along with its requirements, limitations, and best practices.
• VirtioFS vs Shared Datastores: Explore the differences between these storage approaches and when each one makes sense.
• Practical use cases: Discover how VirtioFS can support AI/LLM inference, shared training datasets, and File System as a Service (FSaaS) scenarios while reducing storage duplication.
• Live Q&A: Ask your questions about VirtioFS configuration, storage architecture, and real-world use cases, and get practical guidance from OpenNebula experts.

Join us to learn how VirtioFS can help you simplify file sharing, make better use of your storage resources, and support data-intensive workloads in your OpenNebula environment.
