BUT. usb emulation is resource intensive. i have a testcase with 64 VMs on a dual quadcore xeon and usb alone almost uses the resources of 2 cpus. so i decided to introduce an option for 'console-only' vms. but in that case i would like to have ps/2 mouse also disabled in case someone has the wrong option and complains than that his mouse is unsynchronized. so 'console-only' should be no mouse at all.
