The automated approach includes managing a paging storage pool defined within one or more storage devices for holding logical memory pages external to physical memory managed by a hypervisor of the processing system. The managing includes: responsive to creation of a logical partition within the processing system, automatically defining a logical volume in the paging storage pool for use as a paging device for the new logical partition, the automatically defining occurring absent use of a filesystem, with the resultant paging device being other than a file in a filesystem; and automatically specifying the logical volume as a paging space device for the new logical partition and binding the paging space device to the new logical partition, wherein the logical volume is sized to accommodate a defined maximum memory size of the new logical partition. | 12-10-2009 |
20090307690 | Managing Assignment of Partition Services to Virtual Input/Output Adapters - Automated management of partition service assignment to a virtual input/output (VIO) adapter is provided. Responsive to creation of a new partition service in a data processing system, a partition priority number is determined for the new partition service, and, for each VIO adapter, the partition priority numbers of the partition services currently assigned to that VIO adapter are summed. For a VIO adapter with a lowest sum of partition priority numbers, logic determines whether assigning the new partition service to that VIO adapter results in its summed partition priority number being above a predefined threshold, and the new partition service is assigned to a VIO adapter based, at least in part, on whether assigning the new partition service to the VIO adapter with the lowest sum of partition priority numbers results in that VIO adapter's summed partition priority number exceeding the predefined threshold. | 12-10-2009 |
20090307713 | Hypervisor-Based Facility for Communicating Between a Hardware Management Console and a Logical Partition - A hypervisor-based facility is provided for communicating between a hardware management console (HMC) and a logical partition of a data processing system.

The forwarding includes receiving the transport primitive at the hypervisor and forwarding the cargo of the transport primitive to the target endpoint. The cargo includes the request or response from the source endpoint, and the hypervisor forwards the cargo absent inspection or parsing of that cargo. The target endpoint is the other one of the logical partition or the hardware management console of the data processing system. | 12-10-2009 |
