The Get_Time_Slice_Priority service returns the time-slice execution flags,
the foreground and background priorities, and the percent of CPU usage for a
specified virtual machine.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
VM         Specifies a handle identifying the virtual machine for which to
           retrieve information.
 
Return Value
 
The EAX, ECX, EDX, and ESI registers contain the following information:
 
Register  Description
────────────────────────────────────────────────────────────────────────────
EAX       Specifies status flags from the CB_VM_Status field in the virtual
          machine's control block. It can be one of the following values:
 
          Value                 Meaning
          ──────────────────────────────────────────────────────────────────
          VMStat_Exclusive      Exclusive execution.
 
          VMStat_Background     Background execution.
 
          VMStat_High_Pri_Back  High-priority background execution.
 
ECX       Specifies the foreground time-slice priority. The high word is
          always 0.
 
EDX       Specifies the background time-slice priority. The high word is
          always 0.
 
ESI       Specifies the percentage of total CPU time used by the virtual
          machine.
 
Comments
 
The percentage of CPU time indicates the maximum amount of time the virtual
machine can run. If the virtual machine releases its time slice, this actual
amount of CPU time will be lower because the system grants the released time
to other virtual machines.
