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
