A mechanism for random cache line selection in virtualization systems is disclosed. A method includes maintaining a secondary data structure representing a plurality of memory pages, the secondary data structure indexed by a subset of each memory page, determining an index of a received new memory page by utilizing a subset of the new memory page that is a same size and at a same offset as the subset of each memory page, comparing the index of the new memory page with the indices of the secondary data structure for a match, utilizing a main data structure to perform a full page memory comparison with the new memory page if a match is found in the secondary data structure, and updating at least one of the size of the subset, the number of subsets, and the offsets of the subsets used to index the memory page. |
