Virtual machine IP (Internet Protocol) address detection system and method in cloud computing

Abstract

A virtual machine IP address detection system and method in cloud computing relates to the cloud computing field and comprises a management server which comprises a tracking module and a computational node which comprises a detection agency module, network cards of virtual machines and local machines are respectively connected with a net bridge, and the virtual machines and the local machines are operated by the computational node. The detection steps includes that step 1, the computational node sniffs all the ARP (Address Resolution Protocol) broadcasting message to obtain all the IP addresses of the virtual machines operated on the computational node and transmits the IP addresses to the tracking module and step 2, the tracking module synchronously receives all the IP addresses information of the virtual machines obtained from the computational nodes. The virtual machine IP address detection system and method in the cloud computing has the advantages of simultaneously supporting the detection of dynamic IP addresses and static IP addresses of the virtual machine, being good in timeliness and satisfying the management requirement of the cloud computing system to the virtual machine IP address.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a system and method for detecting IP addresses of virtual machines in cloud computing. Background technique [0002] The cloud computing system based on virtualization technology can improve the utilization rate of system resources by abstracting and simulating the physical resources of the computer into several logical resources. Since the cloud computing system is based on the Internet, each virtual machine needs to communicate with other nodes in the network through a network protocol, so the allocation and management of virtual machine network IP addresses is an important aspect of the cloud computing system. [0003] There are roughly two methods for IP address management in existing cloud computing systems: [0004] 1. IP address management based on external DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) service. The cloud computing system i...

Problems solved by technology

After the user statically modifies the IP address inside the virtual machine, the IP address statically configured by the user cannot be detected using the above method

[0008] (2) The timeliness is not high. When the IP address of the virtual machine changes due to the restart of the virtual machine or the timeout of the IP address assigned by DHCP, etc., this method cannot be perceived immediately. Instead, the above method needs to be executed periodically to obtain the information of the IP change.

[0010] The cloud computing system has a built-in DHCP service. By configuring and managing the DHCP service, you can control the IP address of the virtual machine in the network. You can know the IP address of the virtual machine by viewing the leases (lease) file of the DHCP service. However, this method still does not support user static Configure the IP address of the virtual machine. When the user uses a static configuration IP address, the system will not be able to recognize the IP address of the virtual machine

[0011] To sum up, the existing technology cannot support the management method of statically configuring the IP address of the virtual machine, which limits the flexibility of the user to use the virtual machine to a certain extent
