§arcbox-fs
High-performance filesystem service for ArcBox.
This crate implements VirtioFS-based file sharing between host and guest, providing near-native file I/O performance.
§Key Features
- Zero-copy: Direct memory mapping when possible
- Parallel I/O: Concurrent request handling
- Intelligent caching: Host-side metadata and data caching
- FUSE protocol: Compatible with standard virtiofs drivers
§Architecture
Guest: mount -t virtiofs arcbox /mnt/arcbox
