0xC0000225 Error trying to install Windows 2008 R2 (Or other x64 Windows)

As I was attempting to play with Windows 2008 R2, which only comes in 64bit flavors, I received this error when trying to start the setup:

nothing useful nothing useful nothing useful 0xC0000225 blah blah blah blah blah

This was on the latest version of VirtualBox, on a 32bit host. At first I thought it was a bug in VirtualBox, since it didn’t support 64bit guests on 32bit hosts for so long, but it turns out that when I enabled IO APIC for that Virtual machine, everything worked fine !

Happy testing.
