Comparison Of Virtual Machines
Comparison of virtual machines may refer to: * Comparison of platform virtualization software * Comparison of application virtual machines In this list ''platform'' refers to emulation of an entire physical machine, ''application'' refers to the byte code and similar machines used by various programming languages. {{dab ...

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. The table below compares basic information about platform virtualization hypervisors. General Features * Providing any virtual environment usually requires some overhead of some type or another. Native usually means that the virtualization technique does not do any CPU level virtualization (like Bochs), which executes code more slowly than when it is directly executed by a CPU. Some other products such as VMware and Virtual PC use similar approaches to Bochs and QEMU, however they use a number of advanced techniques to shortcut most of the calls directly to the CPU (similar to the process that JIT compiler uses) to bring the speed to near native in most cases. However, some products such as coLinux, Xen, z/VM (in real mode) do not suffer the cost of CPU-level sl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comparison Of Application Virtual Machines
Application virtualization software refers to both application virtual machines and software responsible for implementing them. Application virtual machines are typically used to allow application bytecode to run portably on many different computer architectures and operating systems. The application is usually run on the computer using an interpreter or just-in-time compilation (JIT). There are often several implementations of a given virtual machine, each covering a different set of functions. Comparison of virtual machines :JavaScript machines not included. See List of ECMAScript engines to find them. The table here summarizes elements for which the virtual machine designs are intended to be efficient, not the list of abilities present in any implementation. Virtual machine instructions process data in local variables using a main ''model of computation'', typically that of a stack machine, register machine, or random access machine often called the memory machine.
