Difficulty: MediumCPU Architecture Cooling and Sockets

An IT support technician is configuring a workstation to host 64-bit client virtual machines for a development team. When launching the hypervisor, an error indicates that hardware-assisted virtualization is disabled. Which of the following processor features or settings should the technician enable in the system's UEFI/BIOS configuration to resolve this issue?

  1. Intel VT-x or AMD-V hardware virtualization supportAnswer
  2. B
    Dual-channel memory configuration across alternating motherboard slots
  3. C
    Higher power supply wattage rating to cover peak processor draw
  4. D
    Immediate physical replacement of the motherboard and processor

Answer

Intel VT-x or AMD-V hardware virtualization support
Hardware-assisted virtualization extensions (Intel VT-x for Intel processors and AMD-V for AMD processors) allow hypervisors to run guest operating systems with direct access to hardware virtualization capabilities. Enabling this option in the UEFI/BIOS menu directly resolves hypervisor errors regarding disabled hardware virtualization.

Step-by-Step Solution

1
Analyze the error message reported by the hypervisor
Identified that the hypervisor cannot execute 64-bit virtual machines because hardware virtualization support is disabled at the system level.
Modern 64-bit hypervisors rely on processor-level hardware extensions to manage guest virtual machine operations safely and efficiently.
2
Identify the required CPU architecture feature
Selected Intel VT-x (Intel Virtualization Technology) or AMD-V (AMD Virtualization) as the corresponding processor feature.
These specific instruction set extensions enable hardware-assisted virtualization on Intel and AMD processors respectively.
3
Determine the corrective action in firmware
Access the motherboard's UEFI/BIOS configuration menu and enable the Intel VT-x or AMD-V setting.
Many motherboard manufacturers disable hardware virtualization extensions by default for security or power management reasons.
