| Abstract: | Through direct device access, the influence of Virtual Machine (VM) on system performance could be decreased. Meanwhile, current device drivers could be used by guest operating systems. A method of direct Universal Serial Bus (USB) device access in virtual environment was proposed, and a model of direct device access and work flow based on QEMU were designed. The experimental results show the VM can directly access varied USB devices with the help of this method, and attain data transmission of acceptable rate. |
