+== Windows 7 Example ==
+
+This example shows how to bring up Win7 nodes. It does not use the old containers system. It has two nodes in a single LAN, then spins up a single Win7 node on each.
+
+NS file with two nodes, both running the {{{PNODE-BASE}}} image. 
+{{{
+#!tcl
+set ns [new Simulator]
+source tb_compat.tcl
+
+tb-make-soft-vtype container0 {pc2133 MicroCloud dl380g3}
+
+set base1 [$ns node]
+tb-set-node-os $base1 PNODE-BASE
+tb-set-hardware $base1 container0
+tb-set-node-failure-action $base1 "nonfatal"
+
+set base2 [$ns node]
+tb-set-node-os $base2 PNODE-BASE
+tb-set-hardware $base2 container0
+tb-set-node-failure-action $base2 "nonfatal"
+
+set lan1 [$ns make-lan "$base1 $base2" 100Mb 0.0ms DropTail]
+tb-set-ip-lan $base1 $lan1 10.0.0.1
+tb-set-ip-lan $base2 $lan1 10.0.0.2
+
+$ns rtproto Static
+$ns run
+}}}
+
+Create a new experiment with the NS file above. *Do not* swap in the experiment. 
+
+We run our own configuration database on the {{{chef}}} node. This is not required, but keeps our configuration separate from the "official" configuration database.
+
+{{{
+#!sh
+users: > ssh chef
+chef: > cd src/config_server
+chef: > git pull ~chef-user/config_server   # grab the newest code from chef-user.
+chef: > ./runserver.py -l debug -p 5323 -d $(pwd)/config.db    # full path to DB and unused port.
+}}}
+
+Create a {{{nodes.json}}} file which describes the Win7 nodes to create:
+
+{{{
+#!json
+[
+        {
+                "host": "base1",
+                "name": "billg",
+                "image_url": "http://scratch/containers/deter_win7.box",
+                "image_os": "windows",
+                "image_type": "vagrant",
+                "image_name": "deter/win7",
+                "interfaces": [
+                    { "address": "10.0.0.101", "mac": "de:ad:be:ef:00:bf" }
+                ]
+        },
+        {
+                "host": "base2",
+                "name": "ballmer",
+                "image_url": "http://scratch/containers/deter_win7.box",
+                "image_os": "windows",
+                "image_type": "vagrant",
+                "image_name": "deter/win7",
+                "interfaces": [
+                    { "address": "10.0.0.102", "mac": "de:ad:be:ef:00:c1" }
+                ]
+        }
+]
+}}}
+
+Note that the Win7 nodes are in the same subnet at the physical nodes.
+
+Load the configuration into our configuration server running on {{{chef}}}. This must be done *before* swapping in the experiment as the configuration server must request control network addresses from DETER. 
+
+{{{
+#!sh
+users: > /share/config_server/bin/initialize_containers.py -p deter -e neo-win7 -f neo-win7.nodes.json -P 5323 -l debug
+}}}
+
+Note that {{{neo-win7.nodes.json}}} is the JSON file above and we use the port of our own config_server.
+
+Output should not contain {{{[ERROR]}}} or {{{[WARN]}}} messages. Here's an example of a good run:
+
+{{{
+#!sh
+01-27 09:29:11 __main__     INFO     Log level set to debug
+01-27 09:29:11 __main__     DEBUG    using base url: /exp/deter/neo-win7/insert
+[OK   ] : Initializing containers from neo-win7.nodes.json for use in experiment deter/neo-win7
+01-27 09:29:11 __main__     DEBUG    sending url: http://chef:5323/exp/deter/neo-win7/insert/containers
+[OK   ] : upload_node_file: Connecting to server chef:5323
+[OK   ] : upload_node_file: Posting node data ... url=/exp/deter/neo-win7/insert/containers
+[OK   ] : Upload_node_file: Getting Response
+[OK   ] : Good response from server. Message: Nodes added: billg, ballmer
+[OK   ] : All is well. Nodes initialized.
+}}}
+
+Now swap in the experiment:
+
+{{{
+#!sh
+users: > swapexp -wNe deter,neo-win7 in
+}}}
+
+Once swapped in, we log into a base node and kick off the chef processes to create and start the Win7 node.
