Network I/O workloads are dominating in most of the cloud data centers today. One way to improve inter-VM communication efficiency is to support co-resident VM communication using a faster communication protocol than the traditional TCP/IP commonly used for inter-VM communications regardless whether VMs are located on the same physical host or different physical hosts. Although several co-resident VM communication mechanisms are proposed to reduce the unnecessary long path through the TCP/IP network stack, to avoid communication via Dom0, and to reduce invocation of multiple hypercalls when co-resident inter-VM communication is concerned. Most state of the art shared memory based approaches focus on performance, with programming transparency and live migration support considered.
