Software that supports virtual machine is called as :

  • A.Virtual machine monitor
  • B.Hypervisor
  • C.Kernel
  • D.Both (A) and (B)

Answer: D

The answer is Both (A) and (B).

The software layer that creates and runs virtual machines, sharing the physical hardware among them, is called a virtual machine monitor (VMM). The same software is also called a hypervisor; the two names are used interchangeably (for example in describing type 1 hypervisors such as Xen and type 2 hypervisors such as VirtualBox).

The kernel is the core of an ordinary operating system. A guest operating system's kernel runs on top of the hypervisor, but it is not the software that supports the virtual machines.
