rust-hypervisor-firmware | repository contains a simple firmware

rust-hypervisor-firmware is a Rust library. rust-hypervisor-firmware has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This repository contains a simple firmware that is designed to be launched from anything that supports loading ELF binaries and running them with the PVH booting standard. The purpose is to be able to use this firmware to be able to load a bootloader from within a disk image without requiring the use of a complex firmware such as TianoCore/edk2 and without requiring the VMM to reuse functionality used for booting the Linux kernel. Currently it will directly load a kernel from a disk image that follows the Boot Loader Specification. There is also minimal EFI compatibility support allowing the boot of some images that use EFI (shim + GRUB2 as used by Ubuntu). The firmware is primarily developed against Cloud Hypervisor but there is also support for using QEMU's PVH loader. This project was originally developed using Firecracker however as it does not currently support resetting the virtio block device it is not possible to boot all the way into the OS.
