Vhost-user devices

This directory contains the implementation of vhost-user devices.

Code Locations

• vmm - Implements vhost-user vmm device; i.e. vhost-user frontend.
• device - Implements vhost-user device backend; i.e. vhost-user backend.

Usage

Vhost-user

First, start a vhost-user device with the crosvm devices command. Here we use the block device as an example, but the basic usage is same for all of devices.

$ crosvm devices --block vhost=/path/to/socket,path=/path/to/block.img

Then start a VM with a vhost-user block device by specifying the same socket path.

$ crosvm run -r rootfs.img --vhost-user block,socket=/path/to/socket <crosvm arguments>
