Run 64bit nested vm in Workstation 8

Hello Experts,

I get the following error while installing ESXi 5 on workstaion 8. My cpu is a Intel core2Quad.

I would like to run 64bit nested vms. Is there any way to make it work?

As per http://ark.intel.com/Products/VirtualizationTechnology , Intel core2Quad is not EPT enabled.

Is there any way to make 64bit nested vm to work with out EPT?

.

Thank You
