Which of the following items belong to the underlying virtualization core module provided for the processor in the KVM architecture? (Multiple choice)

Question

Options

• Akvm.vm
• Bkvm.ko
• Ckvm-amd. ko
• Dkvm-intel.ko

• A
  22% (10)
• B
  78% (35)

Explanation

KVM's virtualization core consists of three loadable kernel modules: kvm.ko (B) is the platform-independent base module containing the core virtualization logic shared across all architectures, while kvm-intel.ko (D) and kvm-amd.ko (C) are hardware-specific modules that interface with Intel VT-x and AMD-V processor extensions respectively - all three must work together to enable full hardware-assisted virtualization. Option A (kvm.vm) is a fabricated distractor; no such module exists in the KVM subsystem - the .vm extension is meaningless in this context, whereas real KVM components use the .ko (kernel object) extension standard for Linux kernel modules. A useful memory tip: think "KVM = 1 brain + 2 CPUs" - kvm.ko is the common brain, and the two CPU-vendor modules (kvm-intel.ko, kvm-amd.ko) are the processor-specific engines; you always need all three present, but only one vendor module activates at runtime depending on your hardware.
