10. The method of claim 1 , further comprising: identifying a page of memory that is the same in the first partition and the second partition; and removing the page from one of the first partition and the second partition, wherein the page that remains is shared by the first partition and the second partition.
1. A method of facilitating memory access, said method comprising: providing a first partition within a system configuration, the first partition configured to support an operating system (OS) designed for a first address translation architecture, wherein configuration of the first partition to support the OS designed for the first address translation architecture is indicated in a configuration data structure, and wherein the first partition is not configured, as indicated in the configuration data structure, to support an OS designed for a second address translation architecture; and providing a second partition within the system configuration, the second partition configured to support the OS designed for the second address translation architecture, the second partition not configured to support the OS designed for the first address translation architecture, wherein the first address translation architecture is structurally different from the second address translation architecture, and wherein the first partition is a paravirtualized partition in which a guest of the first partition assists in handling address translation faults corresponding to host translations, and the second partition is a virtualized partition in which handling of address translation faults corresponding to host translations is independent of assistance from a guest of the second partition.
