I have Virtualbox 4.1.20 in Ubuntu 12.04 32 Bit (With PAE) and I want to run Ubuntu Server 64 Bit on the Guest. Is this possible?. I ask since I get the following warning:
I want to make sure that there is no option to "emulate" this. I have a 64 bit CPU that supports virtualization. The Intel DZ68DB motherboard with an Intel I7 2600 CPU.
