The known_hosts file is built from the +shared ssh host key that xCAT distributes to the nodes. To build the key for a +node, you are only required to have the node in the database and name resolution + working for the node. You do not have to be able to access the node. +Having this file will avoid the ssh warning when nodes are automatically added to the known_hosts file.
