QEMU

QEMU Overview

QEMU, a versatile open-source emulator, operates in user-mode and system emulation to run programs and full computer systems. With support for various instruction sets like x86, ARMv8, and PowerPC, it offers features such as saving VM states, multi-architecture emulation, and efficient disk image storage.

QEMU Components

Key components of QEMU include the Tiny Code Generator (TCG) for code translation, an Accelerator for performance enhancement, and support for multiple disk image formats. Its Object Model facilitates dynamic type registration and system management for user creatable types.

Parallel Emulation and Integration

QEMU enables parallel execution of virtual CPUs, supporting ARM, Alpha, PowerPC, x86, and other architectures. It integrates with platforms like VirtualBox, Xen-HVM, and KVM for enhanced device emulation, I/O virtualization, and hardware virtualization features.
