Abstract
As disclosed herein a method, executed by a computer, for enabling live partition mobility using ordered memory migration includes receiving a request to initialize a migration of a logical partition (LPAR) to a destination system. The method further includes creating a list which includes memory page identifiers corresponding to memory pages of the LPAR. The memory page identifiers of the list are ordered according to a page transfer priority. The method further includes identifying memory pages of the LPAR that will be unmodified during an estimated duration of time of the migration. The method further includes updating the list, based on the identified memory pages of the LPAR that will be unmodified during the estimated duration of time of the migration. The method further includes migrating the LPAR based on the list. A computer system, and a computer program product corresponding to the method are also disclosed herein.
