+ *  Add this to your host tag:
+ *    - <prop id="plugin/dvfs/governor" value="performance" />
+ *
+ *  Valid values as of now are: performance, powersave, ondemand, conservative
+ *  It doesn't matter if you use uppercase or lowercase.
+ *
+ *  For the sampling rate, use this:
+ *
+ *    - <prop id="plugin/dvfs/sampling_rate" value="2" />
+ *
+ *  This will run the update() method of the specified governor every 2 seconds
+ *  on that host.
+ *
+ *  These properties can also be used within the <config> tag to configure
+ *  these values globally. Using them within the <host> will overwrite this
+ *  global configuration
