Abstract

A method of triggering a computational procedure for virtual machine migration includes receiving by a cloud server, reply connection data from a client end host, and determining if the computational procedure for virtual machine migration is initiated according to the reply connection data. The virtual machine migration is performed upon completion of the computational procedure. A browser intercepts the reply connection data to reply to the cloud server when the client end host accesses a web page via the browser. The reply connection data from the client end host is used for determining whether the computational procedure is initiated or not so as to lower a cloud server computation load by reducing the computational procedures performed.
