Explanation
Hardware virtualization requires the CPU and BIOS to support virtualization extensions (Intel VT-x or AMD-V), which must be enabled in the motherboard BIOS before a hypervisor can run.
Common mistakes.

- C. There is no minimum L1 cache size requirement of 1 MB for virtualization - cache size does not determine virtualization capability.
- D. Digitally signed drivers are a Windows driver signing requirement unrelated to enabling hardware virtualization technology on a motherboard.
Concept tested. BIOS virtualization technology enablement for hypervisors
