AW: [Xen-API] power state evaluation

Ok – I gave the DomU 2 CPUs and got the following result for VM_metrics.get_record():

Array

    [VCPUs_params] => Array

            [cpumap1] => 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31

            [cpumap0] => 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31

            [cap] => 0

            [weight] => 256

    [last_updated] => 20070816T19:55:34

    [uuid] => 30c8c9f5-6d8d-2f05-32d1-423cb2054d97

    [VCPUs_flags] => Array

            [1] => Array

                    [0] => blocked

                    [1] => online

            [0] => Array

                    [0] => blocked

                    [1] => online

    [start_time] => 20070816T19:51:43

    [memory_actual] => 268435456

    [state] => Array

            [0] => blocked

    [VCPUs_utilisation] => Array

            [1] => 102

            [0] => 0.00037114269606261139

    [VCPUs_number] => 2

    [VCPUs_CPU] => Array

            [1] => 0

            [0] => 1

Why is there only one state for both CPUs? Or is this an aggregated value for all VCPUs.

What does the CPU Utilisation 102 mean? I supposed to be a percentage value to be between 0.0-1.0.

If I call VM.get_record() I get an key named

    [power_state] => Running

This is the power state of the vm ie running, halted, suspended etc.

If I fetch the metrics by VM_metrics.get_record() I get a similar information:

    [state] => Array

            [0] => running

These are the individual statues of the vcpus, ie running, paused, blocked etc
