The current version of VirtualBox (3.2.6) supports up to 16 GiB of RAM per VM.
FreeBSD community man, HubTou wrote a patch to up the limit to 48 GiB of RAM.
I have tested it with 36 GiB of RAM on real hardware (RHEL5 Linux host).
Host: Dual AMD Opteron Magny-cours (2x12) 24 core + 48 GB of RAM +
VBox 3.2.6 OSE with HubTou patches.
It was also tested on FreeBSD 8 host by HubTou.
the following guest systems were able to boot and work:
-Windows Server 2003/x64
-FreeBSD 8.0/64-bit (tested by HubTou)
On Linux guests I have also put a load - ramdisk (via tmpfs).
Plus I have done the full "memtest86" test -- and it PASSED after 30 hours.
After those tests I can recommend to evaluate the patch for inclusion
into VBox 3.3.x line.
Please evaluate the patch of 48 GiB RAM for guests.
