Abstract
A virtual function mapping process, which is capable of being used in connection with the migration of a logical partition to a target system, creates candidate lists for virtual functions assigned to the logical partition, which are populated with candidate physical ports from a target system that are capable of being mapped to such virtual functions. Candidate physical ports are assigned weights based upon their suitability to be mapped to a particular virtual function, and as candidate physical ports are selected for virtual functions, weights for other candidate physical ports for other virtual functions are recalculated to reflect the impact of the selection of candidate physical ports on the suitability of the remaining physical ports for other virtual functions.
