You don't need a 64 bit image. If you have a 64 bit operating system than you
can only execute 64 bit executables. In linux there are 32 bit compatibility
libraries. The offer a 32 bit interface and mediate this to 64 bit. So you can
run a 32 bit vm with compat libraries or native 64 bit vm. The same goes for
code that you want to link to the vm. It needs to fit. What the vm internally
uses for its address space does not depend on this. I think that is confusing
for a lot of people that you can have a 64 bit vm with a 32 bit image.
But does anyone know what is the state of 64 bit vm executables?
