QEMU Overview
QEMU is a free, open-source machine emulator and virtualizer that can run operating systems and programs built for one architecture on a different one, and can also act as a fast virtualizer when paired with a hypervisor like KVM. As an emulator it models CPUs, devices, and whole machines, which makes it valuable for cross-architecture development, running legacy or embedded systems, and testing. As a virtualizer with hardware acceleration it runs guests at near-native speed. It underpins many higher-level virtualization tools. The offline installer/build installs without a network connection. It supports disk snapshots, copy-on-write image formats, and a wide range of emulated network and storage devices, and can boot from ISO images or raw disks for flexible test setups.
