Virtual machine network system and creation method thereof

Abstract

The invention provides a virtual machine network system that comprises at least one virtual machine network. The virtual machine network includes a specific network bridge; first virtual network cards on all virtual machines in the virtual machine network are connected with the specific network bridge; and network bridges in different virtual machine networks are isolated from each other. Besides, the virtual machine network also comprises connection channels that are used for connecting virtual machines on different physical machines, wherein the virtual machines belong to one same virtual machine network; and the specific network bridge in the virtual machine network is connected to the connection channels by a second virtual network card. According to the invention, it is allowed that there are repeated network segments between different virtual machine networks, so that no IP conflict will occur. In addition, restriction that virtual machines with a same network segment should be distributed on a same physical machine according to a current technical scheme can be broken; and there is no more special requirement on distribution of virtual machines.

Description

technical field [0001] The invention relates to the field of distributed computing, in particular to a virtual machine network system and a creation method thereof. Background technique [0002] In recent years, cloud computing has developed rapidly and has become one of the hotspots in industry and research. It is the development of Parallel Computing, Distributed Computing and Grid Computing, or the commercial implementation of these computer science concepts. Cloud computing is the result of the mixed evolution and leap of concepts such as virtualization (Virtualization), utility computing (Utility Computing), IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service). The "cloud" in cloud computing refers to some virtual computing resources that can be maintained and managed by themselves, usually some large server clusters, including computing servers, storage servers, broadband resources, etc. Cloud computing centralizes all co...

AI Technical Summary

Problems solved by technology

Due to the limited number of virtual nodes that each physical machine can create, this solution cannot create a medium-to-large virtual machine network

When the number of virtual machines for application tasks is small, the resource utilization of physical machines is not high

[0007] (2), the communication between different virtual machines in repeated network segments cannot be realized in the same physical network

Because it stipulates that different virtual machines with duplicate network segments cannot be distributed on the same physical machine, and because the routing table of its virtual tunnel router specifies the destination network segment for communication, even virtual machines with duplicate network segments distributed on different physical machines cannot communication

[0008] (3) Too many tunnel links

[0009] (4) Communication of Ethernet data frames at the link layer between virtual machines cannot be realized

The IP tunnel used in this solution can only realize the encapsulation of IP packets and point-to-point connection, but cannot complete the communication of Ethernet data frames

[0010] (5) In this solution, the virtual machine IP can only use private IP, because it does not achieve complete isolation from the real network segment

[0011] To sum up, the existing technology still lacks a solution to effectively build multiple virtual machine networks, and cannot provide cloud computing users with a network topology that is closer to reality, and cannot meet the needs of enterprise collaboration or network simulation.
