Berrangé Currently when using VNC the "password" flag turns on password based authentication. The actual password has to be provided separately via the monitor. This introduces a "password-secret" option which lets the password be provided up front. $QEMU --object secret,id=vncsec0,file=passwd.txt \ --vnc localhost:0,password-secret=vncsec0 Signed-off-by: Daniel P.
