RVVM
The RISC-V Virtual Machine
RVVM is a high-performance virtual machine and emulator designed for running RISC-V operating systems and applications on non-native hardware, with a strong emphasis on portability, security, and efficiency. It implements a fully spec-compliant RISC-V architecture, supporting modern instruction sets and extensions while maintaining a lean and modular codebase. One of its most notable features is its tracing JIT compiler, which enables significantly faster execution compared to traditional emulation approaches like QEMU’s TCG. The system is capable of running full operating systems such as Linux, FreeBSD, and OpenBSD, as well as supporting userland emulation for running RISC-V applications directly on foreign hosts. RVVM includes a rich virtual hardware environment, including networking, storage devices, and input systems, allowing for realistic system-level emulation.
