Abstract:
1. A computer-implemented method for migration of logical partitions in a computing system in which the logical partitions share computing resources, comprising: determining available bandwidth of network adapters in the logical partitions that will perform the migration; computing central processing unit (“CPU”) capacity needed for fully using the determined available bandwidth for the migration; determining an amount of unallocated CPU capacity in a shared processor pool, the shared processor pool representing processors that are shared by the logical partitions; responsive to determining that sufficient unallocated CPU capacity is available to meet the computed CPU capacity needed, allocating a first portion of the unallocated CPU capacity among the logical partitions that will perform the migration to thereby grow the CPU capacity of the logical partitions that will perform the migration and commencing the migration; and responsive to determining that sufficient unallocated CPU capacity is not available to meet the computed CPU capacity needed, performing:
