  • Method, apparatus and program product for managing memory in a virtual computing system
    Patent number: 7890712
    Abstract: A method for managing memory in a virtual computing system is provided. The method comprises providing updated monitor data for a plurality of data domains in the virtual computing system and determining based upon the updated monitor data provided whether there is a memory constraint in a memory of the virtual computing system. Further, the method comprises calculating based upon the updated monitor data, when the memory constraint is determined, a total release-amount of the memory that is to be released by the virtual computing system in order to relieve the memory constraint and issuing a notification to release the total release-amount of the memory in order to relieve the memory constraint. The method further comprises assessing based upon the updated monitor data, when the memory constraint is ended, a reuse-amount that can be reused by the plurality of virtual guests.
