The virtual computing environment integrated with virtual machines (VMs) and virtual overlay networks possesses many important advantages in cloud computing and green computing. However, the un-negligible overhead of existing virtual networks prevents their vast use in high-performance distributed computing. This paper has designed and implemented a high-speed virtual network system VNET/P. VNET/P is a layer 2 network abstract for virtual machines, which enables a distributed collection of virtual machines to be maintained in a location independent way across wide-area network. Different from the existing virtual network in user layer, VNET/P is embedded into an open-sourced Palacios virtual machine monitor (VMM), has much higher bandwidth and performance scalability, and achieves near-native performance and negligible overhead on 1Gbps Ethernet.
