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 computer-implemented method provides checkpoint high-available for an application in a virtualized environment with reduced network demands. An application executes on a primary host machine comprising a first virtual machine. A virtualization module receives a designation from the application of a portion of the memory of the first virtual machine as purgeable memory, wherein the purgeable memory can be reconstructed by the application when the purgeable memory is unavailable. Changes are tracked to a processor state and to a remaining portion that is not purgeable memory and the changes are periodically forwarded at checkpoints to a secondary host machine. In response to an occurrence of a failure condition on the first virtual machine, the secondary host machine is signaled to continue execution of the application by using the forwarded changes to the remaining portion of the memory and by reconstructing the purgeable memory.
