Sorry Mate for the late reply. I hope you got it fixed by now. Nova user has no password, as the service is not interactive, it needs passwordless access to the compute nodes. To enable this create a .ssh directory in the Nova user’s home directory, its specified in the /etc/passwd file entry for nova. 1) Edit /etc/passwd to have the following: nova:x:115:122::/var/lib/nova:/bin/bash 2) next you need to generate rsa keys for each node and assign those to every other node, so as the root user on every host do:

$pwd (should be in /var/lib/nova)$mkdir .ssh $chmod 700 .ssh$cd .ssh $ssh-keygen – press “enter” for each prompt create an "authorized_keys" file and copy the id_rsa.pub from each host into each others authorized_keys file. So 3 hosts equals 3 entries for each host's authorized_keys file.$chmod 600 authorized_keys – make sure the authorized_keys file is read/write by nova only Log into each host from every other host, if prompted to accept a key, do so! $su - nova$ssh nova@compute2 $ssh nova@compute1 Please let me know if you need any more clarification in any steps.
