VM을 SLA/고객 단위 group으로 묶고 deduplication과 reprovisioning의 메커니즘·정책을 group 경계 안에 제한한다. adaptive scan rate, demand-based reprovisioning, hypervisor-level secondary cache를 제공하며 KVM/KSM을 cgroup 기반으로 확장한다.

Technical interpretation: 멀티테넌트 최적화는 효율 메커니즘뿐 아니라 정책 적용 범위 자체를 tenant boundary에 맞춰야 한다. Group-based Memory Oversubscription for Virtualized Clouds MapReduce, MPI, file-I/O workloads를 사용한 KVM 평가에서 strict inter-group isolation을 유지하면서 workload별 정책으로 intra-group memory efficiency를 확보했다. 공개 초록은 정량값을 제시하지 않는다. system-wide memory oversubscription이 깨뜨리는 멀티테넌트 격리를 보존하면서 그룹 내부 메모리 효율을 얻을 수 있는가? lab 멀티테넌트 최적화는 효율 메커니즘뿐 아니라 정책 적용 범위 자체를 tenant boundary에 맞춰야 한다.
