Running multi-OS on a physical machine is the major method to improve the utilization of computer. With the widely use of virtualization technology in cloud computing, the efficiency of inter-domain communication becomes the key factor for performance of distributed applications especially for some network-intensive applications. The communication synchronous mechanism used by traditional VMM is based on asynchronous signal provided by VMM and often leads to high latency, low performance. In this paper, we design and implement a communication mechanism named OSVSocket which uses inter-processor interruption(IPI) to synchronize and eliminate some useless packet check. We use shared-memory to reduce the time for data copying. Our prototype is implemented on a X86 VMM which is developed by ourselves. The experiment shows that OSVSocket has lower latency and higher performance compared with UNIX IPC.
