QEMU

The Quick Emulator (QEMU) is a free and open-source machine emulator and virtualizer. As a Virtual Machine Monitor (VMM) it supports a number of hypervisors, including the Linux-based Kernel-based Virtual Machine (KVM), Xen, MacOS's HVF, Windows' Hyper-V and a number of others. It is also capable of emulating a number of instruction set architectures on any supported host through its JIT binary translator known as the Tiny Code Generator (TCG). This allows it to emulate full systems or run individual programs compiled for one processor architecture on any other. QEMU supports the emulation of x86, ARM, PowerPC, RISC-V, and many others.
