37 What is FUSE?
40 FUSE is a userspace filesystem framework. It consists of a kernel
41 module (fuse.ko), a userspace library (libfuse.*) and a mount utility

58 Since the virtio-fs device uses the FUSE protocol for file system requests, the
59 virtiofs file system for Linux is integrated closely with the FUSE file system
60 client. The guest acts as the FUSE client while the host acts as the FUSE
61 server. The /dev/fuse interface between the kernel and userspace is replaced
64 FUSE requests are placed into a virtqueue and processed by the host. The
68 Mapping /dev/fuse to virtqueues requires solving differences in semantics
69 between /dev/fuse and virtqueues. Each time the /dev/fuse device is read, the
70 FUSE client may choose which request to transfer, making it possible to
