“…To eliminate redundant processing, socketoutsourcing [21] and VMM-bypass network [22] is invested the guest application which has the awareness [23] of the virtualization. Nevertheless, they only succeeded in improving the performance up to about 60% of the native device, since their notifications of completion were still engaged by the hypervisor.…”

SUMMARYVirtualization is no longer an emerging research area since the virtual processor and memory operate as efficiently as the physical ones. However, I/O performance is still restricted by the virtualization overhead caused by the costly and complex I/O virtualization mechanism, in particular by massive exits occurring on the guest-host switch and redundant processing of the I/O stacks at both guest and host. A para-virtual device driver may reduce the number of exits to the hypervisor, whereas the network stacks in the guest OS are still duplicated. Previous work proposed a socket-outsourcing technique that bypasses the redundant guest network stack by delivering the network request directly to the host. However, even by bypassing the redundant network paths in the guest OS, the obtained performance was still below 60% of the native device, since notifications of completion still depended on the hypervisor. In this paper, we propose vCanal, a novel network virtualization framework, to improve the performance of network access in the virtual machine toward that of the native machine. Implementation of vCanal reached 96% of the native TCP throughput, increasing the UDP latency by only 4% compared to the native latency. key words: device virtualization, multicore processor, para-virtual library, concurrent queue, polling-based notification

“…To support these design objectives, the following three core capabilities should be provided: (i) determining whether the receiver VM is co-resident with the sender VM on the same host, (ii) support both local and remote inter-VM communication protocols and upon detection of local mode of communication, automatically switching to the shared memory based channel, and (iii) the shared memory based inter-VM communication should be incorporated into the existing virtualized platform in an efficient and fully transparent manner [4][5][6][7][8]10].…”

“…This is because the abstraction of VMs supported by VMM technology does not differentiate whether the data request is coming from co-resident VMs or not. Several research projects [2][3][4][5][6][7][8][9][10][11] have demonstrated that. Linux guest domain shows lower network performance than native Linux [12], when an application running on a VM communicates with another VM.…”

Abstract-Network I/O workloads are dominating in many data centers and cloud computing environments today. One way to improve inter Virtual Machine (VM) communication efficiency is to support co-resident VM communication by using shared memory based approaches and to resort to the traditional TCP/IP for inter-VM communications between VMs that are located on different physical hosts. Although a number of independent efforts are dedicated to improving communication efficiency between co-resident VMs, they differ from one another in terms of how the inter-VM communication optimization is carried out and where in the software stack the shared memory channel is established. In this paper, we provide an in-depth overview of the design choices and techniques for optimizing the performance of the co-resident inter-VM communication, with dual objectives. First, we describe the core design guidelines and key issues for optimizing inter-VM communication by using shared memory based mechanisms. Typical issues include choices of implementation layer in the software stack, seamless agility for VM live migration and VM dynamic deployment support, multilevel transparency. Second, we conduct a comprehensive analysis of representative state-of-the-art research efforts and implementation techniques based on the core design guidelines. We also give an analysis of future requirements in advanced features such as reliability, security and stability. The research reported in this paper not only provides the reference for developing the next generation of inter-VM communication optimization mechanisms, but also offers opportunities for both cloud infrastructure providers and cloud service consumers to improve inter-VM communication efficiency in virtualized platforms.

With the advent of virtualization technology and its propagation to the infrastructure of Cloud distributed systems, there is an emergent request for more effective means of communication between virtual machines (VMs) lying on distributed memory than traditional message based communication means. This paper presents a distributed virtual shared memory mechanism called ZIVM (Zero-copy Inter-VM) to ease the programming of inter-VM communications in a transparent way and at the same time to achieve comparable and bearable execution performance. ZIVM has been implemented as a virtual cluster on a hosted virtual machine using the KVM hypervisor. Experimental results have shown near native performance in terms of latency and bandwidth.
