1# vHost 2 3A pure rust library for vhost-user. This is a fork of 4[rust-vmm/vhost](https://github.com/rust-vmm/vhost). 5 6 7 8The 9[vhost-user protocol](https://qemu.readthedocs.io/en/latest/interop/vhost-user.html#communication) 10aims to implement vhost backend drivers in userspace, which complements the ioctl interface used to 11control the vhost implementation in the Linux kernel. It implements the control plane needed to 12establish virtqueue sharing with a user space process on the same host. It uses communication over a 13Unix domain socket to share file descriptors in the ancillary data of the message. 14 15The protocol defines two sides of the communication, frontend and backend. Frontend is the 16application that shares its virtqueues, backend is the consumer of the virtqueues. Frontend and 17backend can be either a client (i.e. connecting) or server (listening) in the socket communication. 18
