Claim Text:
1. A method in a data processing system for processing a service request, the method comprising: obtaining by a service partition of the data processing system a service request from a logical partition of the data processing system, the logical partition having been created by and executing above a hypervisor of the data processing system, and the hypervisor having assigned a processor quantum to the logical partition, and the service partition also having been created by and executing above the hypervisor, wherein the hypervisor enforces security and isolation between the service partition and the logical partition, such that the service partition lacks access to memory management unit configuration and floating-point facilities accessible to the logical partition, and the service partition can access functionality needed to run the service request; and processing the service request by the service partition utilizing the processor quantum assigned to the logical partition by the hypervisor and donated by the logical partition to the service partition.
