 In particular, GENI mesoscale deployments should trust the pgeni.gpolab.bbn.com SA; the official FOAM installation guide includes this step, or you can get the cert from http://www.pgeni.gpolab.bbn.com/ca-cert/pgeni.gpolab.bbn.com.pem if you need it.
 
+== Changing FlowVisor password in FOAM ==
+
+FOAM's database stores information about FV, including its hostname and password.  If you want to change FV's password, you need to change it both in FV itself, and also in FOAM.
+ * Change the password in FlowVisor: this assumes `/etc/flowvisor/config.xml` FlowVisor's config, and is owned by user `openflow`:
+   * Change the password in flowvisor's config:
+{{{
+$ sudo service flowvisor stop
+$ sudo -u openflow fvconfig chpasswd /etc/flowvisor/config.xml fvadmin
+Enter password for account 'fvadmin' on the flowvisor:
+Enter password again
+$ sudo service flowvisor start  
+}}}
+   * If you store the password in `/etc/flowvisor/fvpasswd`, change it there too by hand:
+{{{
+$ sudo vi /etc/flowvisor/fvpasswd
+}}}
+ * Change the password in FOAM.  Future versions of foamctl will support the `config:set-flowvisor-info` command.  If you are running foam-0.6.3, that command doesn't exist yet, so you'll need to use a helper script which invokes curl to talk to FOAM:
+   * Copy the script `change_foam_fvinfo.py` from [https://openflow.stanford.edu/display/FOAM/Scripts+for+admins] on your foam
+   * Ask FOAM for the current FlowVisor information, so you can set any fields you do not want to change to the same values again:
+{{{
+$ foamctl get-config --key="flowvisor_info" --passwd-file=/opt/foam/etc/foampasswd
+{
+ "value": {
+  "passwd": "<old_fv_passwd>",
+  "xmlrpc_port": 8080, 
+  "host": "<old_fv_host>",
+  "json_port": 8081
+ }
+}
+}}}
+   * Invoke that script to set FOAM's FlowVisor info the same way you would on an initial install:
+{{{
+$ python change_foam_fvinfo.py --passwd-file=/opt/foam/etc/foampasswd
+FlowVisor Hostname: <old_fv_host>
+FlowVisor XMLRPC Port [8080]: 
+FlowVisor JSON RPC Port [8081]: 
+fvadmin user password: 
+{
+ "status": "success"
+}
+}}}
