A method for obtaining the IP address of a virtual machine in a vcenter environment

Abstract

The present invention provides a virtual machine IP address acquisition method in a Vcenter environment, the method does not require special hardware requirements, is adaptable to various network environments, and is flexible in application; the method includes the following steps: 1) After the system is started, the Vcenter-poller Get the virtual machine information from the Vcenter interface, extract the virtual machine name and the corresponding MAC address, if a virtual machine has multiple MAC addresses, then generate multiple records of the virtual machine name and MAC address; 2) execute SNMP on the switches in the network ‑poller, the MAC address and IP address of the network data are saved in the switch MIB library, and the SNMP poller needs to be executed regularly, and the obtained MAC and IP address pairs are stored in the MAC‑IP Table; 3) After executing SNMP‑poller, execute IP-match, find out the corresponding relationship between the virtual machine name and IP address according to the Name-MAC Table and MAC-IP Table, and store it in the Name-IP Table, 4) This part of the virtual machine cannot be obtained by executing SNMP-poller on the switch Therefore, host-poller is executed to obtain the correspondence between the MAC and IP addresses of the virtual machine from the physical machine through SNMP.

Description

technical field [0001] The invention relates to the field of cloud computing virtualization management, in particular to a method for obtaining an IP address of a virtual machine in a Vcenter environment. Background technique [0002] Vcenter (VMware vCenter Server) provides a scalable and extensible platform that lays the foundation for virtualization management to centrally manage VMware vSphere environments. Virtual machines are configured, scheduled and monitored through Vcenter, greatly improving IT administrators' control over the virtual environment. However, the virtual machine is defined by the virtual machine name in Vcenter. Since the IP address of the virtual machine is above the virtual machine system level, it cannot be managed by Vcenter, that is, in Vcenter, only the virtual machine system level can be managed. The MAC address (Media Access ControlAddress) of the virtual machine cannot be managed or obtained. Since it is often necessary to manage or locate ...

However, the virtual machine is defined by the virtual machine name in Vcenter. The IP address of the virtual machine cannot be managed by Vcenter because it is above the virtual machine system level, that is, it can only be managed under the virtual machine system level in Vcenter. MAC address (Media Access ControlAddress), unable to manage or obtain the IP address of the virtual machine

Since it is often necessary to manage or locate virtual machines based on IP addresses in IT management, such functions cannot be provided in the Vcenter environment, which brings great inconvenience to IT management
