##
## This file is a dynamic version of the Cloudlab OpenStack profile.  Its core
## class, OSDynSliceManagerHelper, implements the DynSliceManagerHelper interface,
## which the DynSliceManager uses to create and control a dynamic slice where
## nodes are added and deleted on demand.
##
## This script is intended to be both a standalone script, and one that is
## imported by a manager.  In the latter case, the manager looks for several
## key variables to learn about a Helper class or object.  The variables it
## looks for are DYNSLICE_CLASS and DYNSLICE_HELPER.  The former is a class
## it will instantiate; the latter is a an object it will just invoke operations
## on.  Finally, near the very end, it will also handle the case where it runs
## in the Cloudlab Portal to generate an rspec.

The default is this script, because the subnets CloudLab generates for flat networks are sized according to the number of physical nodes in your topology.  However, when the profile sets up your flat OpenStack networks, it tries to enable your VMs and physical nodes to talk to each other---so they all must be on the same subnet.

### Basic Instructions
Once your experiment nodes have booted, and this profile's configuration scripts have finished configuring OpenStack inside your experiment, you'll be able to visit [the OpenStack Dashboard WWW interface](http://{host-%s}/horizon/auth/login/?next=/horizon/project/instances/) (approx. 5-15 minutes).  %s

Please wait to login to the OpenStack dashboard until the setup scripts have completed (we've seen Dashboard issues with content not appearing if you login before configuration is complete).  There are multiple ways to determine if the scripts have finished:
  - First, you can watch the experiment status page: the overall State will say \"booted (startup services are still running)\" to indicate that the nodes have booted up, but the setup scripts are still running.
  - Second, the Topology View will show you, for each node, the status of the startup command on each node (the startup command kicks off the setup scripts on each node).  Once the startup command has finished on each node, the overall State field will change to \"ready\".  If any of the startup scripts fail, you can mouse over the failed node in the topology viewer for the status code.
  - Finally, the profile configuration scripts also send you two emails: once to notify you that controller setup has started, and a second to notify you that setup has completed.  Once you receive the second email, you can login to the Openstack Dashboard and begin your work.

**NOTE:** If the web interface rejects your password or gives another error, the scripts might simply need more time to set up the backend. Wait a few minutes and try again.  If you don't receive any email notifications, you can SSH to the 'ctl' node, become root, and check the primary setup script's logfile (/root/setup/setup-controller.log).  If near the bottom there's a line that includes 'Your OpenStack instance has completed setup'), the scripts have finished, and it's safe to login to the Dashboard.

If you need to run the OpenStack CLI tools, or your own scripts that use the OpenStack APIs, you'll find authentication credentials in /root/setup/admin-openrc.sh .  Be aware that the username in this file is `adminapi`, not `admin`; this is an artifact of the days when the profile used to allow you to customize the admin password (it was necessary because the nodes did not have the plaintext password, but only the hash).

The profile's setup scripts are automatically installed on each node in `/tmp/setup` .  They execute as `root`, and keep state and downloaded files in `/root/setup/`.  More importantly, they write copious logfiles in that directory; so if you think there's a problem with the configuration, you could take a quick look through these logs --- especially `setup-controller.log` on the `ctl` node.
