Abstract: Profile properties in a partition profile are user-configurable through a management entity such as a management console. A partition manager calculates a secondary processing unit entitlement for a logical partition based in part on a secondary processing unit mode property in the partition profile. The secondary processing unit entitlement may be smaller than a primary processing unit entitlement for the logical partition. The partition manager reserves processing units from a secondary shared processor pool equal to the logical partition's secondary entitlement for the logical partition. The primary and secondary processing unit entitlements may be stored in primary and secondary configuration data structures associated with the logical partition. The partition manager may relocate the logical partition to the secondary shared processor pool in response to a predetermined condition.

Abstract: In an approach to allocating hypervisor resources for virtual machine deployment, one or more computer processors determine one or more hierarchically grouped computing resources within a hypervisor. The one or more computer processors receive a selection of one or more hierarchically grouped computing resources. The one or more computer processors apply deployment constraints for a workload to the selected one or more hierarchically grouped computing resources. The one or more computer processors determine, based, at least in part, on the deployment constraints for the workload, one or more computing resources from the one or more hierarchically grouped computing resources.

Abstract: A partition manager relocates a logical partition from a primary shared processor pool to a secondary shared processor pool in response to a predetermined condition, such as a hardware failure. The relocated logical partition is allocated a smaller quantity of processing units from the secondary pool than it was allocated from the primary pool. A quantity of processing units reserved for a second logical partition is identified in the secondary shared processor pool, and a portion of those reserved processing units are allocated to the relocated logical partition. The reserved processing units may be redistributed among multiple relocated logical partitions.

Abstract: A processing apparatus supports execution of executable computer program code, wherein non-instruction data is read from and written to a first address space, while executable instructions are fetched from a second address space. Preferably, the processing apparatus supports execution of a modified or enhanced computer program. The programs and user interfaces in the first address space see only the unmodified first program in the first address space and cannot detect the modified or enhanced program in the second address space.

Abstract: A virtual machine backup method includes utilizing a log to indicate updates to memory of a virtual machine when the updates are evicted from a cache of the virtual machine. A guard band is determined that indicates a threshold amount of free space for the log. A determination is made that the guard band will be or has been encroached upon corresponding to indicating an update in the log. A backup image of the virtual machine is updated based, at least in part, on a set of one or more entries of the log, wherein the set of entries is sufficient to comply with the guard band. The set of entries is removed from the log.

Abstract: A primary processing unit entitlement is determined for a logical partition. A smaller secondary processing unit entitlement is also determined. A partition manager allocates primary processing units to the logical partition from a primary shared processor pool, and the logical partition is activated. The secondary processing units are reserved for the logical partition from a secondary shared processor pool, and the logical partition can be relocated to the secondary shared processor pool in response to a condition such as a hardware failure. The logical partition can continue to process its workload with the fewer processor resources, and can be restored to the primary processing unit entitlement.
