+demo
+====
+
+These instructions will take you through setting up vagrant and libvirt and using these tools to 
+setup and execute a geard demo.
+
+1. [Host setup](#host-setup)
+1. [Demo setup](#demo-setup)
+
+Host setup
+-------------
+
+1.  Install Vagrant 1.6.2
+
+        $ wget https://dl.bintray.com/mitchellh/vagrant/vagrant_1.6.2_x86_64.rpm
+        $ yum -y --nogpgcheck localinstall vagrant_1.6.2_x86_64.rpm
+        $ vagrant version
+        Installed Version: 1.6.2
+        Latest Version: 1.6.2
+
+2.  Setup libvirt 
+
+        $ sudo yum install @virtualization
+        $ wget http://file.rdu.redhat.com/~decarr/dockercon/libvirt-setup.sh
+        $ chmod u+x libvirt-setup.sh
+        $ sudo ./libvirt-setup.sh
+        $ sudo systemctl start libvirtd.service
+        $ sudo systemctl enable libvirtd.service
+
+3. Setup vagrant with libvirt
+
+        $ sudo yum install -y wget tree vim screen mtr nmap telnet tar git
+        $ curl -sSL https://get.rvm.io | bash -s stable
+        $ sudo yum install -y libvirt-devel libxslt-devel libxml2-devel
+        #For this to work I had to "sudo yum install ruby-dev*"
+        $ gem install nokogiri -v '1.5.11'
+        # Make sure that vagrant isn't installed as a gem. If it is, then uninstall it.
+        $ vagrant plugin install --plugin-version 0.0.16 vagrant-libvirt
+
+4.  Setup Vagrant Box and review Vagrantfile
+
+        vagrant box add --name=atomic --provider=libvirt http://download.eng.bos.redhat.com/rcm-guest/staging/walters/images/snaps/20140531.1/vagrant-libvirt/rhel-atomic-host.box
+
+    Clone pmorie's fork and check out the `multi-demo` branch:
+
+        $ git clone git://github.com/pmorie/geard
+        $ cd geard
+        $ git checkout demo-multi
+        $ cd contrib/demo
+        $ cat Vagrantfile
+
+5.  Pull and start local docker registry
+
+        $ docker pull pmorie/geard-demo-registry
+        $ docker run -p 5000:5000 pmorie/geard-demo-registry
+
+6.  Start VMs
+
+        $ vagrant up --provider=libvirt
+        Bringing machine 'default' up with 'libvirt' provider...
+        ==> default: HandleBoxUrl middleware is deprecated. Use HandleBox instead.
+        ==> default: This is a bug with the provider. Please contact the creator
+        ==> default: of the provider you use to fix this.
+        ==> default: Creating image (snapshot of base box volume).
+        ==> default: Creating domain with the following settings...
+        ==> default:  -- Name:          dockercon_489e2b0ea1cb9397b6db6b1bd3a89ad8
+        ==> default:  -- Domain type:   kvm
+        ==> default:  -- Cpus:          4
+        ==> default:  -- Memory:        4096M
+        ==> default:  -- Base box:      atomic
+        ==> default:  -- Storage pool:  default
+        ==> default:  -- Image:         /var/lib/libvirt/images/dockercon_489e2b0ea1cb9397b6db6b1bd3a89ad8.img
+        ==> default:  -- Volume Cache:  default
+        ==> default: Creating shared folders metadata...
+        ==> default: Starting domain.
+        ==> default: Waiting for domain to get an IP address...
+        ==> default: Waiting for SSH to become available...
+
+    If you run into issues, try the following:
+
+        $ rm -fr ./vagrant
+        $ vagrant plugin list
+
+    If you have other third-party plug-ins installed, try to remove them.  In particular, we found
+    errors when running the following plug-ins with vagrant-libvirt:
+
+    1.  vagrant-aws
+    2.  vagrant-openshift
+
+    Be patient. This will bring up two vm instances: `atomic-1` and `atomic-2`.  The provisioner on
+    the initial vagrant up will fetch all required docker images to support the  demo from the local
+    registry, and git clone required content.
+
+7.  SSH access
+
+    Validate that you can reach the VMs with ssh:
+
+        $ vagrant ssh atomic-1
+        $ docker images
+        $ cd geard
+        $ git branch
+        * demo-multi
+          master
+
+        $ vagrant ssh atomic-2
+        $ docker images
+        * demo-multi
+          master
+
+    You can now run rpm-ostree commands, etc.  You can also see the vm running by viewing in 
+    virt-manager:
+
+        $ virt-manager
+
+    You should see be able to see both instances running.
+
+<!---
+8.  OSTree Upgrade
+
+    Next, we need to update to the latest packages.  On both VMs, run the following:
+
+        $ rpm-ostree upgrade
+
+    Then reboot the VMs:
+
+        $ vagrant halt
+        $ vagrant up --provider=libvirt && vagrant provision
+
+    Note: The `vagrant-libvirt` provider does not support the `vagrant up --provision` flag.  The 
+    provision step is required to work around an issue where the private network interface is not
+    brought up on boot by vagrant controller for each VM to communicate.
+-->
+
+8.  Cockpit
+
+    After running `vagrant up`, cockpit should be started and available at: `http://localhost:11001`.
+    Use the following credentials:
+
+        user: root
+        password: atomic2014
+
+    Once you have logged into cockpit, click the 'Add server' button on the right-hand side of the
+    page.  Enter `atomic-2` for the hostname and leave `login with my current credentials` checked.
+
+Demo Setup
+----------
+
+Once the host is set up, you can deploy the demo containers:
+
+        $ cd geard
+        $ contrib/demo/setup-multi.sh
+
+This will install the following containers:
+
+        parks-backend-{1,2,3}
+        parks-db-1
+        parks-lb-1
+
+The setup script will leave `parks-backend-{2,3}` stopped, to be started for scale-up during 
+the demo.  Once the script has run, you should be able to hit the demo from your host in a 
+browser at: `http://localhost:14000`
