METHOD FOR LIVE MIGRATING VIRTUAL MACHINE

摘要

A method for live migrating a virtual machine includes connecting to a virtual machine operated in a first host by a client; transmitting condition data of the virtual machine to a second host by the first host during a transmitting time, the first host and the second host being located at different net domains; transmitting a variance of condition data of the virtual machine generated in the transmitting time to the second host by the first host; providing a notification to the client to reconnect to the second host by the first host; modifying a network packets transmitting rule by the client based on the notification of the first host, and activating the virtual machine by the second host based on the condition data of the virtual machine and the variance of the condition data of the virtual machine thereby maintaining the connection between the client and the virtual machine.

1. A method for live migrating a virtual machine, comprising:
connecting to a virtual machine operated in a first host by a client; transmitting condition data of the virtual machine to a second host by the first host during a transmitting time, wherein the first host and the second host are located at different net domains; transmitting a variance of condition data of the virtual machine generated in the transmitting time to the second host by the first host; providing a notification to the client to reconnect to the second host by the first host; and modifying a network packets transmitting rule by the client based on the notification of the first host such that the client is connected to the second host, and activating the virtual machine by the second host based on the condition data of the virtual machine and the variance of the condition data of the virtual machine, thereby maintaining the connection between the client and the virtual machine.
