+Quanta Research Cambridge OpenStack Stress Test System
+======================================================
+
+Nova is a distributed, asynchronous system that is prone to race condition
+bugs. These bugs will not be easily found during
+functional testing but will be encountered by users in large deployments in a 
+way that is hard to debug. The stress test tries to cause these bugs to happen
+in a more controlled environment.
+
+The basic idea of the test is that there are a number of actions, roughly 
+corresponding to the Compute API, that are fired pseudo-randomly at a nova 
+cluster as fast as possible. These actions consist of what to do, how to
+verify success, and a state filter to make sure that the operation makes sense.
+For example, if the action is to reboot a server and none are active, nothing
+should be done. A test case is a set of actions to be performed and the
+probability that each action should be selected. There are also parameters 
+controlling rate of fire and stuff like that.
+
+This test framework is designed to stress test a Nova cluster. Hence,
+you must have a working Nova cluster.
+
+Environment
+------------
+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
+you have to
+provide 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>
+
+The stress test needs the top-level tempest directory to be on PYTHONPATH
+if you are not using nosetests to run.
+
+For real stress, you need to remove "ratelimit" from the pipeline in 
+api-paste.ini.
+
+
+Running the sample test
+-----------------------
+
+To test your installation, do the following (from the tempest directory):
+
+  PYTHONPATH=. python stress/tests/user_script_sample.py
+
+This sample test tries to create a few VMs and kill a few VMs.
+
+
+Additional Tools
+----------------
+
+Sometimes the tests don't finish, or there are failures. In these
+cases, you may want to clean out the nova cluster. We have provided
+some scripts to do this in the ``tools`` subdirectory. To use these
+tools, you will need to install python-novaclient.
+You can then use the following script to destroy any keypairs,
+floating ips, and servers::
+
+stress/tools/nova_destroy_all.py
