* [Qemu-devel] Bug(?): Can't unset vnc password (v1.0)

In qemu-kvm 1.0 (from ubuntu Precise) I don't seem to be able to UNSET 
the vnc password once it has been set via qemu monitor.
I can set it to "" which is empty password, but a VNC client connecting 
still asks to enter a password. It does log in if I enter the empty 
string, but I think it should not ask the password at all.
Or is there any other way to disable password authentication, different 
from setting an empty password string?
Note: I am using set_password from qemu-monitor (actually libvirt's 
qemu-monitor-command).

Thank you

QEMU must *not* change the VNC authentication method as a side effect of
setting a password.

QEMU does not have any monitor command to let you change the auth
method specified from the command line, but such a command would
be a welcome addition.

Daniel

Well, then there is the opposite bug:

If you start qemu with no vnc password set (client enters without 
authentication), then you set a vnc password via qemu-monitor, now the 
client needs password authentication. Can you confirm this is not the 
intended behaviour?
