Virtual memory is nothing but your hard disk. What happens in main memory (RAM) is for ex :- if you have opened a Microsoft Word, you will type something and you want it to be bold, you will use the bold option. So what scheduler does is it will simply fetches that particular func() and loads it in main mem
Scheduler knows that which process is given the processor, so if that particular process interrupts means it is asking for the page which is not in main mem so, while doing this scheduler gets the address of the interrupted process and looking at this adderss scheduler comes to know about the particular process and fetches the page accordingly.
