Solution Virtualization not Supported, BIOS missing virtualization option?

In my system BIOS virtualization option is missing. After research found that my system doesn't support virtualization.

Laptop model : HP DV6-1152TX Processor : Processor type - Intel Core 2 Duo Processor T6400 * 2.0 GHz, 2 MB L2 Cache, 800 MHz FSB BIOS version : F.25 Operating System : Windows 8.1 pro 64 bit

Please let me know best way to resolve this issue? If I have to change the CPU what are the specifications I need to consider? Does virtualization is essential for Cloudera Quickstart VM. Is there some way one can use Cloudera Quickstart VM without using virtualization or upgrading BIOS and CPU.

Thanks,
