Which statement is true regarding the Linux kernel module that must be loaded in order to use KVM?

  • A. It must be loaded into the kernel of each virtual machine to provide paravirtualization which is required by KVM.
  • B. It must be loaded into the kernel of the host system in order to use the virtualization extensions of the host system's CPU.
  • C. It must be loaded into the kernel of the host system only if the console of a virtual machine will be connected to a physical console of the host system.
  • D. It must be loaded into the kernel of each virtual machine that will access files and directories from the host system's file system.
  • E. It must be loaded into the kernel of the first virtual machine as it interacts with the KVM bare metal hypervisor and is required to trigger the start of additional virtual machines.
