Importing a new version from external source
It is worth noting that KSM and Virtuozzo use totally different strategies for RAM deduplication: KSM provides a constantly running daemon (called ''ksmd'') which scans the HN's memory and merges identical RAM pages gradually over time, whereas Virtuozzo merges requests from different containers to the same physical binaries on disk. In doing so, Virtuozzo incurs no overhead at all, while KSM has a 5-10% CPU overhead depending on its configuration (faster scanning of the HN RAM will require more CPU power).
