OS virtualization is the creation of separate and partitioned run-time environments all within the same overall OS. The way that applications are installed and interact with the OS is not changed, so there are no changes of substance to the application lifecycle. These separate runtime environments rely on a single kernel instance and managed by the host OS each partition in the system shares that kernel. Much of the OS user space, though not the kernel, is replicated in each partitioned runtime environment. Solaris Containers and Zones are one of the better known OS virtualization environments.
