First you need to check why this "Failed to add the host to the list of
known hosts (/var/lib/nova/.ssh/known_hosts)." happens. It maybe file
permissions or so. Then you need to generate an ssh key for the user nova
and add it to the other compute nodes on the authorized_keys file (the
password is not really necessary as soon as you have the keys in place).
