QEMU is a generic and open source machine emulator and virtualizer.
QEMU can be used in several different ways. The most common is for System Emulation, where it provides a virtual model of an entire machine (CPU, memory and emulated devices) to run a guest OS. In this mode the CPU may be fully emulated, or it may work with a hypervisor such as KVM, Xen or Hypervisor.Framework to allow the guest to run directly on the host CPU.
The second supported way to use QEMU is User Mode Emulation, where QEMU can launch processes compiled for one CPU on another CPU. In this mode the CPU is always emulated.
QEMU also provides a number of standalone command line utilities, such as the qemu-img disk image utility that allows you to create, convert and modify disk images.
Features include:
- Emulates a number of CPU architectures.
- Run programs for another Linux/BSD target, on any supported architecture.
- Virtualization – run KVM and Xen virtual machines with near native performance.
- Cross-platform support – runs under Linux, FreeBSD, NetBSD, OpenBSD, macOS, and Windows.
