Get_Next_VM_Handle

The Get_Next_VM_Handle service returns the handle of the next virtual machine in the virtual machine list maintained by the system. 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.

Parameters

VM

Specifies a handle identifying a virtual machine.

Return Value

The EBX register contains the handle of the next virtual machine in the list.

Example

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:

; modify the VM state

VMMcall Get_Next_VM_Handle
