Research and design of inter-communication in DVMM

Virtualization is a hot topic nowadays. For archiving supporting single system image (SSI) on multi-computers, virtualization plays an important role. The distributed virtual machine monitor, or DVMM, is a technology which supports by integrating multiple physical computers' resources. The hypervisor of DVMM provides some modules to integrate resource of multi-nodes, such as process virtualization and memory virtualization, but lack of I/O devices. This paper gives a reliable communication which is hypervisor-oriented. It is analyzed with helping of a special virtual machine — I/O domain, which gives all I/O devices driver, including networking. Thus, the hypervisor running on different nodes can cooperate with each other. Compared with communication mechanisms of other clusters, this solution has advantages of high performance and easy implementation.
