Method for keeping remote operation of virtual machine uninterrupted

Abstract

The invention relates to a method for keeping the remote operation of a virtual machine uninterrupted, and the remote operation of the virtual machine can be still kept to be uninterrupted when entity equipment for operating the virtual machine is changed. The method comprises the following steps of: carrying out a snapshot procedure on the virtual machine of a first computer, transmitting a snapshot result to a second computer, and establishing a same virtual machine according to the snapshot result; acquiring the media access control address of a virtual network card of the newly established virtual machine; sending an address resolution protocol packet of the newly established virtual machine to an exchanger in a broadcast mode by the second computer; and stopping the operation of the virtual machine in the first computer, and operating the virtual machine in the second computer. By adopting the method, the operation of the virtual machine by a user can not be interrupted due to the transaction of the entity computer.

Description

technical field [0001] A method for managing a virtual machine, in particular, relates to a method for keeping the remote operation of the virtual machine uninterrupted. Background technique [0002] With the rapid development of integrated circuits, the computing power of the central processing unit has been improved. Therefore, a single server can run multiple virtual machines (Virtual Machines) at the same time, so as to provide each user with an independent operating environment. Each virtual machine can be regarded as its own independent computer. The virtual machine also has memory, storage space, computing power and network connection functions, so a separate operating system can be run in the virtual machine, and the Internet can also be connected through the virtual machine. [0003] Therefore, in order to reduce the cost of computer hardware, many companies have provided various operating environments with different requirements for employees to work by running m...

In this way, the virtual machine 110 can no longer receive the packet smoothly

[0007] Since the virtual machine 110 is relocating from the old server to the new server, the time spent may exceed the storage time of the image relationship, which will cause the switch to delete the mapping

In this way, the virtual machine 110 needs to re-establish the image relationship, and a lot of time will be wasted on network connectivity.
