ChinaV: Building Virtualized Computing System

Virtualization technology has attracted much attention in recent years. This paper describes the vision and mission of ChinaV, which is the national fundamental research program for virtualization technology in China. Furthermore, related topics about single host virtualization, multiple VM management schemes and desktop virtualization will be introduced. We first describe a remote memory virtualization scheme and a VCPU management scheme for efficient use of physical resource. Then we describe a novel live VM migration approach based on deterministic replay with execution trace. Multiple VM management schemes are also introduced for multi-VM virtualization. In desktop virtualization field, we present the LVD, a system that combines the virtualization technology and inexpensive personal computers to realize a lightweight virtual desktop system. All of those schemes and systems are good practices of virtualization solution and they have become a strong foundation of our future work.
