I am getting below error
This virtual machine is configured for 64-bit guest operating systems. However, 64-bit operation is not possible.
This host does not support Intel VT-x.
It sounds like you have a 64-bit processor but are running a 32-bit operating system. VT-X needs to be enabled in your BIOS for the VM to work. You'll have to consult your motherboard or laptop manufacturer's documentation to see how to do this.
