Abstract
A system, method, and computer-usable medium for probing hypervisor tasks in an asynchronous environment. According to an embodiment of the invention, the partition firmware sends a request for data to the hypervisor. When the hypervisor receives the request for data, the hypervisor returns a taskID that identifies the task allocated to handle the request. Partition firmware records the taskID and a timestamp, which indicates the time in which the hypervisor received the request. A timer is set to measure the amount of time elapsed since the task ID was received by a requesting partition firmware. If the hypervisor has not provided the partition firmware with the requested data after a predetermined time period measured by the timer has elapsed, the partition firmware inquires about the status of the task associated with the taskID. If the task is still running, the partition firmware returns control of the partition to the operating system.
