Topology management method and system of virtual machines

A topology management method for virtual machine (VM), the method used for a topology management system, the topology management system comprising a base-information database, a topology information database and an information register processing unit, the base-information database recording a plurality of internal information in a VM, the method comprising:

• a) the information register processing unit monitoring the base-information database;
• b) the information register processing unit updating the topology information database with the plurality of internal information of the VM stored in the base-information database;
• c) the topology information database receiving an alias name of the VM defined by a setting terminal, the alias name being defined according to an assigned task of the VM;
• d) the topology information database recording the alias name and generating a mapping between the alias name and the plurality of internal information of the VM in the topology information database.

A topology management system for virtual machine (VM), comprising:

• a physical machine (PM) installing a VM thereon;
• a base-information database operatively connected to the PM and configured to record a hostname and an IP address of the VM;
• a topology information database comprising an upper-layer table and a lower-layer table;
• an information register processing unit operatively connecting to the base-information database and the topology information database, the information register processing unit configured to monitor the base-information database and to update the topology information database with the plurality of internal information of the VM stored in the base-information database,
• a setting terminal operatively connected to the topology information database and having an application program interface (API), the API defining the alias name of the VM after receiving external operation and writing the alias name into the topology information database;
• wherein the upper-layer table records a mapping between the alias name of the VM and the hostname of the VM, the lower-layer table records a mapping between the hostname of the VM and the IP address of the VM.
