What term describes software that separates a VM's resources from hardware and provisions them for the VM?

• A. Hypervisor
• B. Hypervisors
• C. Virtualization Manager
• D. Emulator

Answer: (B)

At the heart of virtualization is the software layer that sits between the physical hardware and the virtual machines, taking the raw resources of the host and provisioning them to each VM while keeping the VMs isolated from one another. This is the hypervisor. It creates virtual hardware for each VM and controls access to CPU, memory, storage, and I/O devices, ensuring that each VM gets its allocated share without stepping on others’ resources. There are two broad flavors: Type 1 hypervisors run directly on the hardware (bare-metal) and manage all resources themselves, while Type 2 hypervisors run on top of an existing operating system and use that OS to access hardware. While you might see the term used in the plural form when talking about multiple such systems or products, the concept is described by the singular term hypervisor. The plural simply refers to more than one instance or type of this software, but the function remains the same: separating VM resources from hardware and provisioning them to the VMs.
