Abstract
Systems, methods, and apparatuses for managing memory usage in virtualized computing environments are provided herein. An example method includes generating a random key, associating the key with a page or range of pages in a memory, and selectively deduplicating pages based upon the key associated with each respective page.
Claims20
A method, comprising:
- generating a key, wherein the key is randomly generated;
- associating the key with a page or range of pages in a memory;
- and
- selectively deduplicating pages based upon the key associated with each respective page.
1 more element
A system, comprising:
- a first memory;
- and
- a processing device, operatively coupled to the first memory, to:
- generate a key, wherein the key is randomly generated;
- associate the key with a page or range of pages in a second memory;
- and
- selectively deduplicate pages based upon the key associated with each respective page.
4 more elements
A non-transitory computer-readable storage medium storing instructions which, when executed by a processing device, cause the processing device to:
- generate a key, wherein the key is randomly generated;
- associate the key with a page or range of pages in a memory;
- and
- selectively deduplicate pages based upon the key associated with each respective page.
