Yes, QEMU applied a broken fix for CVE-2011-0011 which means whenever
you set a password, they reset auth type to 'VNC' (type=2).

Thanks for your answer.
I tried to comment out
vs->auth = VNC_AUTH_VNC;
inspired by your patch (the whole patch did not work with my version of
qemu ) and it fixed the issue. I will check how the situation will
evolve, whether qemu developers will fix it or not.
