Relocating data in a virtualized environment maintained by a hypervisor administering access to memory with a Cache Page Table (‘CPT’) and a Physical Page Table (‘PPT’), the CPT and PPT including virtual to physical mappings. Relocating data includes converting the virtual to physical mappings of the CPT to virtual to logical mappings; establishing a Logical Memory Block (‘LMB’) relocation tracker that includes logical addresses of an LMB, source physical addresses of the LMB, target physical addresses of the LMB, a translation block indicator for each relocation granule, and a pin count associated with each relocation granule; establishing a PPT entry tracker including PPT entries corresponding to the LMB to be relocated; relocating the LMB in a number of relocation granules including blocking translations to the relocation granules during relocation; and removing the logical addresses from the LMB relocation tracker.
A method of relocating page tables amongst memory modules in a virtualized environment, the page tables comprising a Cache Page Table (‘CPT’) and a Physical Page Table (‘PPT’), the CPT comprising virtual to logical address mappings, the CPT accessible by an operating system executing in a partition of the virtualized environment maintained by a hypervisor, the PPT comprising virtual to physical address mappings, the PPT accessible by a computer processor, the method comprising:
A method of relocating data amongst memory modules in a virtualized environment maintained by a hypervisor, the hypervisor administering access to memory by a partition with a Cache Page Table (‘CPT’) and a Physical Page Table (‘PPT’), the CPT comprising virtual to physical address mappings, the CPT accessible by an operating system executing in a partition of the virtualized environment, the PPT comprising virtual to physical address mappings, the PPT accessible by a computer processor, the method comprising:
An apparatus for relocating data amongst memory modules in a virtualized environment maintained by a hypervisor, the hypervisor administering access to memory by a partition with a Cache Page Table (‘CPT’) and a Physical Page Table (‘PPT’), the CPT comprising virtual to physical address mappings, the CPT accessible by an operating system executing in a partition of the virtualized environment, the PPT comprising virtual to physical address mappings, the PPT accessible by a computer processor, the apparatus comprising the computer processor, computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:
A computer program product for relocating data amongst memory modules in a virtualized environment maintained by a hypervisor, the hypervisor administering access to memory by a partition with a Cache Page Table (‘CPT’) and a Physical Page Table (‘PPT’), the CPT comprising virtual to physical address mappings, the CPT accessible by an operating system executing in a partition of the virtualized environment, the PPT comprising virtual to physical address mappings, the PPT accessible by a computer processor, the computer program product disposed in a computer readable storage medium, wherein the computer readable storage medium is not a signal, the computer program product comprising computer program instructions that, when executed by a computer, cause the computer to carry out the steps of:
