![]() ![]() ![]() Operating systems will often run their portion of the code (the kernel) in as low of a level as possible so that it can effectively manage the system and the userspace- ring 0, thus referred to as the kernel mode. In x86, software runs in privilege levels (often called rings) and are organized by the operating system. Thus, hypervisors can be seen as a type of emulator, in which one system pretends to be another by translating its code into something that can be executed.īecause the IBM PC's architecture, x86, is a complex instruction set by design, it is able to do complex operations that allow it to efficiently emulate other platforms. Hypervisors are a type of software that manage virtual machines which are, in theory, emulated PCs. However, there is also a port to FreeBSD (only OSE version). The currently supported host operating systems include Linux, Mac OS X, Windows XP, Windows Vista, Windows 7, Solaris and OpenSolaris. Within the VirtualBox application, additional guest operating systems, each known as a Guest OS, can be loaded and run, each with its own virtual environment. Inside the VirtualBox application, you can create many virtual machines sometimes called "guest computers" which act much like physical computer hardware, except you can't touch it because it's all simulated inside your real physical computer hardware. The physical computer hardware and operating system you have before you install VirtualBox is the "host computer" and "host operating system". VirtualBox is installed on an existing host operating system. Oracle VM VirtualBox is an x86 virtualization software package maintained by Oracle Corporation as part of its family of virtualization products.
