A method for data transmission in a system is disclosed. The system includes a computer (1) and a peripheral device (9), which are connected to each other via a network (8). The computer has hardware resources (2), including a network interface (2.3) and a controller (4), which is designed to provide a virtual machine system in that it maps the hardware resources (2), including the network interface (2.3) onto logical interfaces (5, 5.3) in virtual machines (4). A peripheral device adapter (10) provided in the computer (1) is mapped by the controller (3) onto a logical peripheral device interface (11) in one of the virtual machines (4) and data is exchanged between the peripheral device (9) and the virtual machine (4) via the network (8), the peripheral device adapter (10), and the logical peripheral device interface (11) while bypassing the logical interfaces (5.3) mapping the network interface (2.3) into the virtual machines (4).
