VMM이 CR3와 event timing을 이용해 guest task의 I/O-boundedness를 추론하고 block/network event와 상관시킨다. 관련 I/O task를 처리하는 동안만 vCPU를 `partial boosting`하고, `PBratio`로 과도한 boost를 제한한다.

PBratio와 inspection window가 responsiveness, throughput, fairness 사이 trade-off를 만든다. Technical interpretation: coarse VM-level boost를 task/event 기간으로 축소하고 사용량 cap을 두면 intra-VM heterogeneity를 다룰 수 있다. Task-aware Virtual Machine Scheduling for I/O Performance synthetic mixed workloads와 realistic applications에서 I/O responsiveness/throughput을 개선하면서 VM 간 CPU fairness를 유지했다. full text는 inspection-window와 correlation이 block throughput을 높이고 false boosting을 줄임을 보이지만, 공개 summary에 단일 headline speedup은 없다. CPU-bound와 I/O-bound task가 같은 VM에 섞일 때 CPU fairness를 깨지 않고 I/O task만 빠르게 wake/run할 수 있는가? lab coarse VM-level boost를 task/event 기간으로 축소하고 사용량 cap을 두면 intra-VM heterogeneity를 다룰 수 있다.
