Sorry, I think there is some misunderstanding about virutal techonology.

In a virutal hardware box, the guest OS inside it does not know where it 
is. It may be a litter or much slower than in a real hardware box, but 
the memory footprint should never been any difference. That's why many 
developers use Microsoft Virutal PC or VMWare to test there programs. 
Think about it - you don't have to boot into another OS or go to another 
computer that may be 50 meters far just to test a small problem of your 
progarm!

So I think I I have FC3 installed in a real hardware box, the memory 
footprint of the JVM will be the same.
