Abstract

A trigger method of computational procedure for virtual machine migration is disclosed. A cloud server simultaneously receives reply connection data from a client end host, and determines if the computational procedure for migration virtual machines is initiated according to the connection data. The virtual machines migration is performed upon the computational procedure completed, wherein, the browser intercepts the connection data to reply to the server when client end host accessing to web page via browser. The reply connection data from the client end host is used for the determining if the computational procedure is initiated or not so as to lower the server computation loading by reducing the computational procedures performed.
