FSaaS Datastore for Shared Storage File Systems (virtiofs)

[MarioRobres]

Description
This feature introduces a new OpenNebula datastore driver (sharedfs) designed to manage directory-based "images" on shared filesystems (NFS, Lustre, etc.) instead of traditional disk image files (qcow2). Any folder that lives on a shared storage backend can be registered as an image and then exposed to VMs through virtiofs.

Use case

• FSaaS service

• AI model artifacts imported from the Hugging Face marketplace are stored as directories
