Abstract
A mechanism for touch screen emulation for a virtual machine is disclosed. A method of the invention includes providing an emulation of a touch screen device to a virtual machine (VM) managed by a hypervisor for emulation of the touch screen device by the VM, receiving touch gesture information related to a touch gesture received in the session window of the VM that is managed by the hypervisor, sending an interrupt to the VM that informs the VM of detected touch screen activity in the session window of the VM on the touch screen device, wherein in response to the interrupt the VM receives the touch gesture information in order to utilize in determining screen coordinates of the touch gestures within the session window of the VM.
