hi gerd,

with 0.12.4 it is still the case that a total idle vm takes about 6-8% 
of a 2.4GHz Xeon Core.

see: http://dev.cs1.dlh.net/usb-on-off.png

until approx 13.00 cet its with -usb -usbdevice tablet and after the 
reboot only with
the ps/2 mouse.

i'm fine generally not using the usb emulation for console only guest 
systems, but in that
case I would like to disable ps/2 mouse as well.

br,
peter
