I've read that you can run a 64-bit guest OS on a 32-bit host OS through virtualisation (Hyper-V or sth. similar).

How much RAM can the guest OS use/allocate in this case? (assuming 4GB+ RAM)

Your Guest OS can't access more Memory than your Host OS.

added an image - so the RAM is managed by the host OS and not by the Hypervisor? –  Milde Mar 18 '10 at 15:23
    
@Milde The memory is Managed by the OS at the software Level, so the Guest can't have more memory than the Host. –  Michael B. Mar 18 '10 at 15:26
    
ty, I marked the answer as "the correct answer". I also figured out, that that you need a 64bit system to run Hyper-V on it. :) –  Milde Mar 18 '10 at 15:41
