Zusammenfassung:A method includes establishing two partitions, including a first partition and a second partition, in a computer system. The method further includes designating a first memory page in memory space controlled by the first partition, designating a second memory page in memory space controlled by the second partition, storing an address of the first memory page in an address mapping array that is accessible by the first partition and storing an address of the second memory page in an address mapping array that is accessible by the second partition. In addition, the method includes exchanging the address of the first memory page in the address mapping array that is accessible by the first partition with the address of the second memory page in the address mapping array that is accessible by the second partition.
