Suppose your hardware does not support virtualization technology. In that case, you will receive an error message, as shown in the above figure, when you try to install software that requires hardware virtualization enabled at the BIOS level. Softwares such as VMware, the android emulator will throw this message if hardware virtualization is not supported. This was the case with the old generation of intel based processor computers. These days almost 95% of the hardware support virtualization.
