Embodiment

[0095] This embodiment provides a virtual machine communication system based on a PCIE network, such as figure 1 As shown, at least 2 hosts 10 (Host), a PCIE switch 20 (PCIESwitch) and a subnet management server 30 are included; a virtual machine monitor (VMM) 111 and at least one virtual machine (VM) are run on each host 10 ) 101; the PCIE switch 20 is connected to all hosts to realize data forwarding between hosts. The subnet management server 30 is connected to the PCIE switch 20, and is used for maintaining the corresponding relationship between hosts and virtual machines in the system. The host of the system provided in the embodiment of the present invention may specifically be an ordinary computer, mobile terminal, workstation or server, a dedicated server, etc., and the subnet management server may be an ordinary host or a dedicated host in the system. The present invention is not specifically limited.

[0096] The host, the PCIE switch and the subnet management serv...

Abstract

Provided are a PCIE network-based virtual machine communication system and method. The system comprises: a source host which comprises a virtual machine monitor and at least one virtual machine, wherein the virtual machine monitor on the source host is communicatively connected to the virtual machine on the source host; A virtual machine on the source host, as a source virtual machine, processes a network request intercepted on a TCP / IP protocol stack and sends same to the virtual machine monitor on the source host; and the virtual machine monitor on the source host sends data contained in the network request to a PCIE NTB address space corresponding to the source host in the PCIE NTB address space corresponding to a target host to which the target virtual machine is subordinate, according to the ID of a target virtual machine of the network request. The present invention uses the PCIE network as a communication mechanism between virtual machines, achieving quick communication between virtual machines; and also breaks through the limitation of the PCIE network, with the PCIE NTB address space in a subnetwork management server being managed and shared based on a subnetwork of the PCIE network, improving the communication speed between virtual machines.

Description

technical field [0001] The invention belongs to the technical field of computer Internet communication, and relates to a virtual machine communication method, in particular to a virtual machine communication method, server and system based on a high-speed peripheral component interconnect Express (PCIE) network. Background technique [0002] With the deployment of more virtualized servers and continuous development of virtualization technology, network virtualization occupies an increasingly important position, and communication among virtual machines (Virtual Machines, VMs for short) is also more frequent. [0003] Currently, communication between virtual machines is mainly based on Ethernet. When communicating between two virtual machines, first, the user-mode application in the virtual machine will call the Socket interface, through the Transmission Control Protocol (Transmission Control Protocol, referred to as TCP) / Internet Internet Protocol (Internet Protocol, referred...
