Canceling the execution of a virtual processor allows an application to abort the call to run the virtual processor (
WHvRunVirtualProcessor) by another thread, and to return the control to that thread. The virtualization stack can use this function to return the control of a virtual processor back to the virtualization stack in case it needs to change the state of a VM or to inject an event into the processor.
