The CPU supports VT, I'm not sure if Sony enable it in the BIOS, you'd have to check.
Do not have the option in the BIOS the only way would be to update the BIOS. But not know how to do this I ask you to help me
The VT supporting BIOS is here:

There are instructions on how to perform the upgrade as well, you should print these and the follow the instructions.
