Hi， When I want to use the VNC tool to connect to the virtual machine, I will be prompted for the virtual machine VNC password. The virtual machine XML file is shown below. Where can I query passwd in the VNC configuration? <graphics type='vnc' port='-1' autoport='yes' keymap='en-us' passwd='*****' passwdValidTo='1970-01-01T00:00:01'> <listen type='network' network='vdsm-ovirtmgmt'/> </graphics> Do you need to change the listen parameter in the libvirtd.conf configuration file.
