Abstract

Recently, virtualization is becoming the critical issue in the cloud computing due to its advantages of resource utilization and consolidation. In order to efficiently use virtualization services, several issues should be taken into account, including data reliability, security, and performance. In particular, a high write bandwidth on the virtual machine must be guaranteed to provide fast responsiveness to users. In this study, we implemented a way of visualizing comparison results between the block write pattern of KVM-based virtual machine and that of the real machine. Our final objective is to propose an optimized virtualization environment that enables to accelerate the disk write bandwidth.

최근 들어 가상화는 자원의 활용 및 통합 등의 장점으로 인하여 클라우드 컴퓨팅의 중요한 요소로 점차 인식되고 있다. 가상화 서비스를 효율적으로 사용하기 위해서는 데이터의 안정성 및 성능, 보안 등의 여러 요소들이 고려되어야 하며, 특히 가상 머신의 실제 디스크 쓰기 성능이 보장되어야 한다. 본 연구에서는 KVM 가상 머신 상의 블록 출력 패턴과 리얼 머신 상에서의 디스크 쓰기 패턴을 비교 분석할 수 있는 가시화 방법을 구현하였다. 본 연구는 이를 기반으로 가상 머신의 디스크 쓰기 속도를 향상시킬 수 있는 최적화된 가상화 환경을 제안하고자 한다.
