How does the computer turn on vt?

VT refers to Intel virtualization technology, which is the hardware-level virtualization technology of CPU. If your computer CPU supports VT, here are the steps to open VT in BIOS/UEFI:

Find options such as "Advanced" or "CPU Configuration", and then find options such as "Intel Virtualization Technology" or "Intel VT-x" and set them to "Enable".

Save the settings, exit the BIOS or UEFI interface, and then restart the computer. You can run virtualization software (such as VirtualBox) after restarting. ) to test whether VT has been successfully turned on.

Please note: virtualization technology needs both hardware and software support, and your operating system and CPU must support hardware-level virtualization technology to turn on VT correctly.
