Abstract:
A method for operating virtual machines on a virtualization platform, the method comprising: embedding, preferably by a toolstack of the virtualization platform, control information in a predetermined memory area of a front-end virtual machine where at least one virtual device is to be initialized, wherein said control information is 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, said control information from said 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 in order to exchange information for initializing said at least one virtual device of the front-end virtual machine, in particular by communicating with said at least one back-end driver via said direct communication channel, wherein said direct communication channel is established based on said control information embedded in said predetermined memory area of the front-end virtual machine. Furthermore, a corresponding virtualization platform is disclosed.

Claim (Index 13):
The method according to  claim 1 , wherein a toolstack of the virtualization platform informs the back-end virtual machine that is in control of a physical back-end device about a new front-end virtual machine having a virtual device being created,\n wherein the toolstack receives new control information on how the new front-end virtual machine can access the back-end virtual machine's back-end driver that controls the physical back-end device, wherein the toolstack writes the new control information into the predetermined memory area inside the new front-end virtual machine before the new front-end virtual machine starts its booting process, wherein the new front-end virtual machine's operating system accesses the new control information to create a direct communication channel with the back-end virtual machine, wherein further communication including finishing initialization of the front-end virtual machine is done via the direct communication channel.
