"Despite the fact that UML now runs in ring 0, it is still a user-mode process, and thus still deserves its name."
Forgive my ignorance but how is this possible? I had always understood ring 0 to be kernel mode and some other ring (normally ring 3 on x86) to be user mode. Can UML have its cake and eat it too?
