mov ebx, VM ; VM handle
VMMcall Get_Time_Slice_Priority

mov [Background], edx ; background time-slice priority

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.
