Certain firewall configurations or instances where the target system is configured to obtain a dynamic IP address may cause trouble with the direct VNC mode in anaconda. In addition, if you lack a console on the target system to see the message that tells you the IP address to connect to, then you will not be able to continue the installation.
The VNC connect mode changes how VNC is started. Rather than anaconda starting up and waiting for you to connect, the VNC connect mode allows anaconda to automatically connect to your view. You won't need to know the IP address of the target system in this case.
To activate the VNC connect mode, pass the
vncconnect boot parameter:
Replace HOST with your VNC viewer's IP address or DNS host name. Before starting the installation process on the target system, start up your VNC viewer and have it wait for an incoming connection.
Start the installation and when your VNC viewer displays the graphical installer, you are ready to go.
