Para virtualization is a virtualization technique that allows multiple operating systems to run concurrently on a single physical machine while requiring modifications to the guest operating systems. Unlike full virtualization, where the hypervisor simulates complete hardware, para virtualization provides an interface that enables the guest OS to communicate directly with the hypervisor, thus avoiding overhead from emulating hardware. This method increases performance by reducing the amount of virtualization needed for certain tasks and allows for efficient resource management. Para virtualization is particularly useful in scenarios where high performance is crucial, as it minimizes the performance impact associated with full virtualization. Why Other Options are Incorrect: A) Full virtualization: This method requires a hypervisor to simulate hardware fully, allowing unmodified guest operating systems to run, which makes it less efficient than para virtualization. C) Server-based virtualization: This is a broad category that includes various virtualization techniques, including those that require a hypervisor. D) Container-based virtualization: This type of virtualization uses containers rather than virtual machines, and while it allows multiple applications to run in isolated environments, it does not run multiple OS instances in the same way. E) Type 2 virtualization: This is a form of virtualization that runs on top of an existing operating system and requires a hypervisor, which contradicts the requirement of not needing one.
