Get_Next_VM_Handle

include vmm.inc

mov     ebx, VM           ; VM handle
VMMcall Get_Next_VM_Handle

mov     [NextVM], ebx     ; next VM handle

Returns the handle of the next virtual machine in the virtual machine list maintained by the system. Uses EBX, Flags.

• Returns the handle of the next virtual machine in the EBX register.

VM

Handle of a virtual machine. The return value identifies the next virtual machine after the specified virtual machine.

Although each virtual machine appears only once in the list, the order of the handles is not guaranteed. The list is circular, so a virtual device scanning the list should stop scanning when the latest handle returned is equal to the first handle returned.

The following example modifies the state of every virtual machine by using the Get_Next_VM_Handle service to retrieve handles of all valid virtual machines:

    VMMcall Get_Cur_VM_Handle

Scan_Loop:

    ; modify the VM state

    VMMcall Get_Next_VM_Handle
    VMMcall Test_Cur_VM_Handle
    jne     Scan_Loop
