Difficulty: EasyVirtual Machine Resource Requirements and Hardware Support

A technician is setting up a desktop computer to host virtual machines for testing software. Upon launching the hypervisor, an error message indicates that hardware-assisted virtualization is disabled. Which feature must be enabled in the system's BIOS/UEFI setup to resolve this issue?

  1. Intel VT-x or AMD-VAnswer
  2. B
    Hyper-Threading (SMT)
  3. C
    Type 1 Bare-Metal Hypervisor Mode
  4. D
    Unified Extensible Firmware Interface (UEFI) Fast Boot

Answer

Intel VT-x or AMD-V must be enabled in the BIOS/UEFI firmware settings.
Intel VT-x (Intel Virtualization Technology) and AMD-V (AMD Virtualization) are CPU instruction set extensions configured within the host motherboard's BIOS/UEFI setup. Enabling these features allows the hypervisor to directly utilize hardware features for virtual machine execution.

Step-by-Step Solution

1
Identify the cause of the hypervisor hardware virtualization error.
The CPU lacks active hardware-level virtualization support features.
Hypervisors require direct CPU hardware extensions to efficiently manage guest virtual machines.
2
Select the BIOS/UEFI setting responsible for hardware virtualization extensions.
Enabling Intel VT-x (for Intel processors) or AMD-V (for AMD processors) resolves the hypervisor error.
These extensions expose hardware features required by hypervisors to host virtual machines.
