Schedules an event for the specified virtual machine. This is an asynchronous service.

• Returns the event handle in ESI. The event handle can be used in subsequent calls to the Cancel_VM_Event service to cancel the event.

VMHandle

Handle of the virtual machine to process the event. This value must be a valid VM handle.

EventCallback

Address of the callback function. For more information about the callback function, see EventCallback.

RefData

Reference data to pass to the callback function.

Since the specified virtual machine must process the event, the system carries out a task switch (if necessary) before calling the callback function. The function can carry out any actions and use any VMM services. The system completes the event processing before the VMM returns from the current interrupt.

For additional information about event callbacks, see Event Callbacks.
