QEMU for Rust, and Rust for QEMU!

This repository provides several QEMU-related crates:

• qemu: QEMU binary installer
• qemu-plugin-sys: Low level bindings to the QEMU plugin API
• qemu-plugin: High level bindings to the QEMU plugin API

The crates work together to enable building QEMU utilities in Rust and running QEMU from Rust code in a machine-specified way.

To see what the crate can do, trace the execution (including syscalls, memory accesses, and instructions) of a program like:

cargo run -r --bin tracer -- -a /bin/ls -- -lah

This repository also provides a crate (qemu) which builds QEMU from source and installs Rust wrappers for QEMU as binaries.

You can install QEMU with (add any additional features you need, e.g. plugins):

cargo install [email protected]  --features=binaries

On some systems, particularly BTRFS systems, /tmp may not be large enough for the temporary build directory (QEMU is quite large to build). In this case, create a directory on your root filesystem (e.g. $HOME/.cargo/tmp) and set CARGO_TARGET_DIR=$HOME/.cargo/tmp when running the install command.
