| 궁금했던 점 | CPU 집약적 백그라운드 작업과 대화형 작업이 같은 데스크톱 VM 안에서 경쟁할 때, vCPU를 동적으로 비대칭화해 사용자 체감 지연을 줄일 수 있는가? |
| 해본 것 | 하이퍼바이저가 백그라운드 작업과 잠재적 대화형 작업을 투명하게 분류하고, 대화형 작업을 호스팅하는 vCPU에는 더 큰 CPU share를, 백그라운드 vCPU에는 더 작은 share를 부여한다. 선택적 guest-OS 확장은 두 종류의 작업을 별도 vCPU에 배치한다. |

| 실제 결과 | KVM/SPICE, 8-vCPU VM, PARSEC `freqmine` 간섭 환경에서 하이퍼바이저 확장만으로 앱 실행시간을 최대 41%, 웹 탐색시간을 최대 31% 개선했다. guest 확장까지 사용하면 각각 최대 70%, 41% 개선했다. 비디오 프레임 드롭도 크게 줄었다. 반면 백그라운드 `freqmine`은 3–20% 느려졌다. |
| 왜 그랬는지 | 높은 fast/slow share 비율은 guest 확장 없이 대화형·백그라운드 스레드가 한 vCPU에 섞일 경우 오히려 성능을 악화시킬 수 있다. 평가는 특정 KVM/SPICE VDI와 대표 대화형 워크로드에 한정된다.
Technical interpretation: VM 단위 우선순위만으로는 intra-VM QoS를 보장하기 어렵고, 작업 의미를 추론해 vCPU share와 guest 배치를 함께 조정해야 한다. |
| 다음에 기억할 것 | VM 단위 우선순위만으로는 intra-VM QoS를 보장하기 어렵고, 작업 의미를 추론해 vCPU share와 guest 배치를 함께 조정해야 한다. |
| 언제 맞는지 | VDI·멀티테넌트 데스크톱에서 대화형 QoS와 백그라운드 처리량의 명시적 trade-off를 설계할 때 직접 적용 가능하다. |
| 신뢰도 | 높음 |
