What causes the message “VT-X/AMD-V hardware acceleration is not available in your system” error?

VT-x/AMD-V is disabled in the BIOS: Another reason for this error message may be that the virtualization technology used by your processor is disabled in the BIOS.

VT-x/AMD-V has been disabled by Hyper-V: Hyper-V is Microsoft’s proprietary virtualization technology. In recent versions of Windows, Hyper-V is automatically enabled and VT-x/AMD-V is disabled to avoid conflicts. However, Hyper-V does not work well with virtual machines.

Your processor does not support VT-x/AMD-V: Some older processors do not support Intel VT-x or AMD-V. If your computer does not support virtualization technology, you will not be able to bypass or fix the error message.
