Patent ID: 8302102

Claim:
A method, in a data processing system, for improving system resource utilization, the method comprising: determining if there is at least one virtual processor in a plurality of virtual processors in a shared resource pool that is ceded; responsive to existence of the at least one ceded virtual processor in the shared resource pool, determining if there is at least one dedicated logical partition configured for a hybrid mode, wherein the at least one hybrid configured dedicated logical partition has a configuration capability similar to that of a dedicated logical partition and in addition, the at least one hybrid configured dedicated logical partition is also allocated resources through shared entitlement; responsive to identifying the at least one hybrid configured dedicated logical partition, determining if the at least one hybrid configured dedicated logical partition requires additional virtual processor cycles; responsive to the at least one hybrid configured dedicated logical partition requiting additional virtual processor cycles, deallocating the at least one ceded virtual processor from the plurality of virtual processors in the shared resource pool; and allocating the at least one ceded virtual processor to a surrogate resource pool for use by the at least one hybrid configured dedicated logical partition.
