Hi Scott,

Both products can only support a 64-bit guest OS if the host supports 
virtualization. This requires a combination of CPU capability (look in 
/proc/cpuinfo for the vmx or svm flag), motherboard support and BIOS 
enablement. If your CPU supports it, it might be switchable in your BIOS 
menus... or you might have a system that doesn't support it at all.
