Use '-vnc :0,password' to turn on password authentication. (In reply to comment #1) > Use '-vnc :0,password' to turn on password authentication. Hi Hoffmann, When I boot up guest with '-vnc :0' (without ',password') in RHEL6, the authentication also works. I'm not sure if it's normal. Yes, the upstream qemu behavior has changed at some point that setting a password implicitly turns on password authentication. RHEL-5 has the old behavior, RHEL-6 the new. If you want a password-protected vnc session you are better explicitly say so using the password flag even in RHEL-6, otherwise there is a window (between starting qemu and setting the password) where it is possible to connect without authentication. IMHO there is no good reason to make RHEL-5 match RHEL-6 behaviour, so I'll rather leave it as-is to avoid unpleasant surprises. |
