After installing AVP you need to first 'ssh' to the AVP server to accept the End User License Agreement (EULA). You need to use the 'root' account and password you configured in the Kickstart File Generator used when installing AVP to access the server through ssh. Detailed instructions can be found in the "Installing Appliance Virtualization Platform" section in the "Deploying Avaya Aura® Applications" (for release 7) document.
