The number of 'ticks' (typically 1/100s) spent by the hypervisor code to run other VMs even though the CPU in the current VM had something runnable. This object will not be implemented on hosts where the underlying operating system does not measure this particular CPU metric. On a multi-processor system, the 'ssCpuRaw*' counters are cumulative over all CPUs, so their sum will typically be N*100 (for N processors).
