I am not a developer, but a long-term contributor, and it is my understanding that software virtualization doesn't hides completely from guest code, and guest code may detect such incorrect behavior, and fail. It just happens to work with most versions of Linux guests and Windows NT-class guests. Using hardware virtualization (VT-x/AMD-V) should result in correct behavior for all x86 code.
