Abstract
A method for operating virtual machines on a virtualization platform includes: embedding control information in a predetermined memory area of a front-end virtual machine where at least one virtual device is to be initialized, the control information being required for initiating a communication with a back-end virtual machine where at least one back-end driver runs; retrieving, by the front-end virtual machine, the control information from the predetermined memory area of the front-end virtual machine; and performing the communication between the front-end virtual machine and the back-end virtual machine via a direct communication channel to exchange information for initializing the at least one virtual device of the front-end virtual machine, by communicating with the at least one back-end driver via the direct communication channel. The direct communication channel is established based on the control information embedded in the predetermined memory area of the front-end virtual machine.
