On my Windows XP SP3 (32-bit) machine (Intel Pentium Dual CPU E2140 1.60GHz, 3GB RAM), I installed VirtualBox (4.0.10). I then tried to install a 64-bit OS like Windows 7 64-bit or Windows Server 2008 R2 64-bit on the VM. However I got an error.
I think the error stated that my machine is unable to run a 64-bit OS but actually VirtualBox in this case should be capable of running 64-bit OSes on a 32-bit host. Is that right?
