제목	Technical Review: Scheduler Support for Video-oriented Multimedia on Client-side Virtualization
궁금했던 점	guest 수정 없이 hypervisor가 video/3D workload를 식별하고 CPU contention 중에도 목표 frame rate를 유지할 수 있는가?
해본 것	framebuffer write 또는 GPU interrupt rate로 frame rate를 추정하고, desired frame rate와의 feedback으로 VM CPU share를 동적으로 조절한다. Xen Credit scheduler의 boost를 multimedia-aware하게 정제한다.
당시 조건	Verification level: full_text. Sources checked: https://doi.org/10.1145/2155555.2155566 https://yonsei.elsevierpure.com/en/publications/scheduler-support-for-video-oriented-multimedia-on-client-side-vi/ https://www.researchgate.net/publication/221636635_Scheduler_support_for_video-oriented_multimedia_on_client-side_virtualization
실제 결과	frame-rate 추정오차는 VLC HighRes 0.79%, Quake3 3.05%, 간섭 중 VLC LowRes 0.55%로 보고됐다. CPU-intensive 경쟁 VM이 있어도 VLC HighRes가 최대 23.976 FPS에 가까운 평균과 낮은 분산을 유지했고, Quake3에도 적절한 share를 배정했다.
왜 그랬는지	Xen Credit, VLC 640×354/1280×720, Quake3 중심 평가다. initial desired frame-rate와 tolerance 설정이 필요하며 display path별 추론 방식이 다르다. Technical interpretation: 애플리케이션 내부 신호가 없어도 low-level device event를 QoS proxy metric으로 만들고 feedback scheduling에 사용할 수 있다.
다음에 기억할 것	애플리케이션 내부 신호가 없어도 low-level device event를 QoS proxy metric으로 만들고 feedback scheduling에 사용할 수 있다.
언제 맞는지	virtualized multimedia client에서 frame-rate-aware CPU allocation에 직접 해당한다.
