I have a I-7 2670QM CPU. My pc bios says "VT (VT-x) SUPPORTED". How can I activate the Virtual Technology (VT)? There is no command in BIOS that allow me to do this operation. Bye.
It could be that your system/motherboard has it ON already. If not, contact them and ask.
What do you plan to do with VT? Run hyper-v?
For a processor this old, you may want to abandon this effort and get new hardware.

If VT-x is supported, it will be enabled/disabled by the BIOS. As Al said, if there is no parameter in BIOS Setup for enabling VT-x, then the BIOS should be enabling it. If it is not, then it is a bug in the BIOS. Unfortunately, for a board built in 2011, there is little chance of getting a BIOS fix for this issue.
