Difference between QEMU and VMware

QEMU vs. VMware

QEMU (short for Quick Emulator) is a free and open-source emulator that performs hardware virtualization. VMware, Inc. is a subsidiary of Dell Technologies that provides cloud computing and platform virtualization software and services.

Binary translation

In computing, binary translation is a form of binary recompilation where sequences of instructions are translated from a source instruction set to the target instruction set.

Comparison of platform virtualization software

Platform virtualization software, specifically emulators and hypervisors, are software packages that emulate the whole physical computer machine, often providing multiple virtual machines on one physical platform.

Dynamic recompilation

In computer science, dynamic recompilation (sometimes abbreviated to dynarec or the pseudo-acronym DRC) is a feature of some emulators and virtual machines, where the system may recompile some part of a program during execution.
