 This particular framework assumes your working Nova cluster understands Nova 

 API 2.0. The stress tests can read the logs from the cluster. To enable this

-provide the private key and user name for ssh to the cluster in the

+you have to provide the hostname to call 'nova-manage' and

+the private key and user name for ssh to the cluster in the

 [stress] section of tempest.conf. You also need to provide the

 value of --logdir in nova.conf:

 

   host_private_key_path=<path to private ssh key>

   host_admin_user=<name of user for ssh command>

   nova_logdir=<value of --logdir in nova.conf>

+  controller=<hostname for calling nova-manage>

 if you are not using nosetests to run.
