077 | QEMU: A Flexible Emulator and Hypervisor

August 9, 2025

What is QEMU?

QEMU (Quick Emulator) is a multifunctional open-source project that acts both as an emulator and a virtualizer, making it a unique tool in the virtualization world. Unlike other hypervisors, QEMU not only runs virtual machines but can also emulate a processor and other hardware components. This dual nature allows it to run operating systems and applications designed for one architecture on a machine with another (for example, running an ARM system on an x86 server).
