Ticket #6578 (closed defect: fixed)
Creating a guest as Windows XP prevents any 64bit guest from installing, even after changing to Windows 7 64bit

Create a new host, keep the guest OS selection as Windows XP (default). Finish the creation. Go into the properties and change the guest OS to Windows 7 64bit. Add the Windows 7 install media. Save changes and boot the guest. About 5 seconds after you see the screen "Starting Windows 7", it will crash with error 0xc0000225, an unexpected error occurs. If you boot to 32bit Windows 7, it won't crash.
To fix, you have to delete the virtual guest, create a new one and be sure to select a 64bit guest OS before creating the guest.
