Hi , when i use VIF_metrics.get_record api function to get the io_read_kbs and io_total_read_kbs of a HVM domU, it returns always 0. When a HVM is created, a vif and a tap devices are generated, how can i get the traffic amount of HVM guests? Is there a relationship between de domU and tap device? the vifs are generated with domU ID, but thats not happend with tap devices.
