Rust-Based VirtIO Backends for Hypervisor-Agnostic Solutions

Explore a conference talk on Project Stratos, a Linaro open source initiative aimed at expanding VirtIO applications. Learn about the project's goal to create hypervisor-agnostic VirtIO backends using vhost-user and virtio protocols. Discover how this approach replaces hypervisor-specific backend drivers with protocol-conforming implementations, enabling vhost-user backend daemons to interact with real hardware and potentially multiplex resources across multiple guests. Examine the implementation of I2C, RNG, GPIO, and upcoming RPMB daemons in Rust, integrated into the rust-vmm project via the vhost-device crate. Follow the project's progress from initial QEMU emulation testing to successful integration with Xen and the xen-vhost-master daemon. Gain insights into future plans for properly integrating xen-vhost-master and the Xen API crate into the rust-vmm project, as well as the development of new vhost-user daemons for complex hardware like cameras and wireless devices.
