+ * bdrv_info_stats(): show block device statistics
+ *
+ * Each device statistic information is stored in a QDict and

+ * The QDict contains the following:
+ *
+ * - "device": device name
+ * - "stats": A QDict with the statistics information, it contains:
+ *     - "rd_bytes": bytes read
+ *     - "wr_bytes": bytes written
+ *     - "rd_operations": read operations
+ *     - "wr_operations": write operations
+ * 
+ * Example:
+ *
+ * [ { "device": "ide0-hd0",
+ *               "stats": { "rd_bytes": 512,
+ *                          "wr_bytes": 0,
+ *                          "rd_operations": 1,
+ *                          "wr_operations": 0 } },
+ *   { "device": "ide1-cd0",
+ *               "stats": { "rd_bytes": 0,
