Filesystem

Each VM presents a normal POSIX filesystem to guest code, backed by a virtual filesystem inside the kernel. At a glance:

• Per-VM virtual filesystem: Every VM gets its own isolated virtual filesystem. One VM cannot see or reach another VM’s files.
• Never touches the host disk: Guest filesystem calls are served entirely inside the kernel and never read or write the real host disk.
• Normal POSIX and Node APIs: The standard node:fs and node:fs/promises APIs work as usual against the virtual filesystem, so ordinary programs run unchanged.
• Mountable backends: You can project host-backed sources into the guest filesystem, Docker-style, including host directories and S3. Mounts are confined to their root, and the guest sees only the mounted subtree.
