See http://www.iemulator.com/iemulator_faq.php, "Is iEmulator based on the BOCHS emulator?". It is perfectly legal. The core of QEmu is licensed under the LGPL, and accordingly, (at least some) sources of iEmulator are freely downloadable. > Also, I am quite new to QEMU and virtualization in general and wanted to > know the difference between QEMU and product like OpenVZ. OpenVZ is a virtualiser, i.e. it uses the hardware -- including the CPU -- of the host, and relies on the OS to handle the sharing parts. Therefore, you can not run unmodified kernels (or Windows for that matter) using OpenVZ. QEmu is a system emulator, i.e. the hardware componentes are emulated. As for the CPU, QEmu uses a technique called "translation" or Just-In-Time compilation in order to execute the code. If the host CPU is of the same type as the emulated CPU, you can use KQEmu or QVEmu to kind-of virtualise the CPU instead. > I suppose QEMU is more like VMware aimed at end users and OpenVZ would > be more for Enterprise servers. Correct. The principal application for QEmu is to run a different OS in a window on your desktop. The principal application for OpenVZ or Zen is to run many virtual computers (servers) on one host.
