Abstract:
1. A processor-implemented method residing in a machine-readable storage medium and to execute on a processor, the method, comprising: receiving, by the processor, a request to save a state of a Virtual Machine (VM), the request received within a processing context of the VM and the request sent from a helper process processing on the VM and the helper process does not wait for response to sending the request, the request sent asynchronously and processed asynchronously by the processor; passing, by the processor, the request to a hypervisor that executes on the processor outside the processing context of the VM; detecting, by the processor, an event raised by the hypervisor indicating the state was saved for the VM; and notifying, by the processor, one or more VM applications executing within the processing context of the VM that the state was saved for the VM.
