You have to have a 64 bit Intel or AMD cpu, but your BIOS also needs to support it. In some bioses you will need to enable a "VT" (or alternative name) setting. Some (presumably older ones) even need a firmware upgrade first...
In virtualbox, in the virtual machine settings (System, acceleration tab), check Hardware Virtualization: Enable VT-x/AMD-V is enabled Good luck.
