Hi,
    I am using "XenAPI -1.0.6" ... I have "Dual Core" machine on which I am working..I am trying  to fetch Dom-0 CPU utilization using XenAPI RPC "get_utilisation()"(class host cpu)....
    Since my machine is dual core this function is yielding me utilization of Core 1 & Core 2 separately(e.g Core ONE - 0.4241242424  & Core TWO - 0.3254842450)..I just want to calculate the overall CPU utilization in percentage for the Dom-0...What is the standard procedure in this case to calculate overall CPU utilization in percentage by considering above two CPU utilizations for each core ?

Thanks,
Kushal Waikar
