RVVM is a high-performance RISC-V virtual machine and emulator written in C, featuring a tracing JIT with x86_64, ARM64, and RISC-V backends. It runs guest operating systems like Linux, FreeBSD, and Haiku, and provides a library API (librvvm) for machine and userland emulation.

Use cases

• run risc-v linux on my x86 machine
• emulate riscv64 without qemu
• test risc-v operating systems like freebsd or haiku
• embed a risc-v virtual machine in my application
• run risc-v binaries on a foreign-arch host
• fast risc-v emulator with jit compilation
• try risc-v in the browser via wasm

When to choose

• you need a fast, lean RISC-V system emulator with JIT acceleration
• you want a portable C library for embedding RISC-V emulation
• you need to boot RISC-V guest OSes like Linux, FreeBSD, or Haiku
• you want userland networking that works on any host OS

When to avoid

• you need to emulate architectures other than RISC-V
• you require the full device ecosystem and maturity of QEMU
• you need production-grade userland emulation, which is still work-in-progress
