`init 3` should kill graphic interface, so some level of blackness is expected. There is no cursor and other VT, accessed by (Ctrl+)Alt+F2, has no login prompt?

Yes, it shows login prompt when switch to Alt+F2. But I think it's not that kind of blackness, normally `init 3` will switch to text mode and show login prompt in current terminal, but this time just got black with a flash underline, no login prompt. Also test with RHEL7.1 GA guest not hit this problem.
