Method and device for controlling Internet protocol (IP) address of virtual machine

Abstract

The invention discloses a method and a device for controlling an Internet protocol (IP) address of a virtual machine. The method comprises the following steps of: when a creation instruction for creating the virtual machine is received, presetting the IP address of the virtual machine; sending the creation instruction to a proxy of a virtualization layer, so the proxy which is positioned on the virtualization layer creates the virtual machine according to the creation instruction and returns a media access control (MAC) address of the created virtual machine; and according to the IP address of the virtual machine and the MAC address of the virtual machine, updating a static address allocation relation of a dynamic host configuration protocol (DHCP) server, so when the virtual machine is started, the DHCP server allocates the IP address to the virtual machine which corresponds to the MAC address according to the static address allocation relation. By the invention, the IP address of the virtual machine can be allocated predictively and automatically, manual intervention is reduced, and the management efficiency and operation efficiency of a cloud computation platform are improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for controlling the IP address of a virtual machine. Background technique [0002] With the improvement of computer hardware processing capabilities and the development of virtualization technology, building a service platform based on virtualization technology, especially a cloud computing platform that incorporates virtualization technology, can effectively expand the capacity of hardware and improve resource utilization. , Simplify the software configuration process, thereby reducing the cost of operating and maintaining computer hardware and software. In a system using virtualization technology, the physical resources of the computer can be abstracted and simulated as logical resources. Computer hardware such as central processing unit, memory, disk and other physical resources can be regarded as a logical resource pool that can be dynamically managed. ...

Problems solved by technology

Among them, the fixed IP address allocation method usually requires manual configuration, which consumes labor costs and is inefficient; although the dynamic address allocation method based on the DHCP protocol can realize the automation of IP address allocation for virtual machines and reduce the relatively inefficient manual operations, but This allocation method cannot predict the mapping relationship between the IP address and the virtual machine before the virtual machine is started, and cannot meet the requirements of some applications on the cloud computing platform that need to specify the mapping relationship between the IP address and the virtual machine in advance.
