Explanation

QEMU is primarily used for hardware emulation, enabling virtual machines to run by emulating CPU, memory, storage, and peripheral devices. Virtualization documentation describes QEMU as a generic and open-source machine emulator and virtualizer. When used alone, QEMU can fully emulate hardware, allowing operating systems compiled for one architecture to run on another. In modern Linux virtualization environments, QEMU is most commonly paired with KVM (Kernel- based Virtual Machine). In this configuration, KVM provides CPU virtualization using hardware extensions, while QEMU supplies device emulation and virtual hardware components. This division of responsibility allows near-native performance while maintaining flexibility. Although QEMU includes utilities such as qemu-img for disk image creation, that is not its primary purpose. VM management is handled by tools like libvirt, virsh, and virt-manager, and monitoring is performed by separate observability tools.
