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.
VM
Specifies a handle identifying the virtual machine for which to retrieve information.
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. | ||
| Register | Description | ||
| 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. |
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.
