US Patent 10055248 Virtual processor scheduling via memory monitoring

Systems and methods for scheduling virtual processors via memory monitoring are disclosed. In one implementation, a hypervisor running on a host computer system may detect a task switch event associated with a virtual processor running on a physical processor of the host computer system. The hypervisor may test a polling flag residing in a memory accessible by the guest software running on the virtual processor and set the polling flag to a non-polling state. The hypervisor may then process the task switch event.
