Title:
  USB keyboard and mouse sucked into qemu-kvm (somewhere)

Status in QEMU:
  Expired

Bug description:
  i am unable to run a command line qemu that does not "suck in" the keyboard 
and mouse of the host PC
  i tried all that i could from the command line parameters i want to run a 
headless gui-less kvm host

  if i specify a second set of keyboard and mouse with the -usb the only thing 
that is diffrent is that i have a keyboard and mouse in the VM if i specify the 
host keyboard and mouse same thing ... the vm is working fine but the host has 
no control , no keyboard. i dont see any output of anything 
  the only recourse i have is ctrl+alt+delete  and that resets the host after 
2-3 times. 

  i tried ctrl+alt, ctrl+alt+x , c , z , 2 , etc... also alt + all those 
combination and alt with F keys 
  no luck. 

  
  my command line looks like this (altough i tried many other variations)
   
  qemu-system-x86_64 -M q35 -enable-kvm \
  -cpu host,kvm=off -m 4096 -smp cpu=4,sockets=1,cores=4,treads=1 \
  -drive file=xyz.qcow2,if=scsi \
  -device vfio-pci, ... (GPU) \
  -device vfio-pci, .... (GPU audio) \
  -usb -usbdevice host:XXXX:XXXX -usbdevice host:XXXX:XXXX \   <<< same 
behaviour with and without
  -vga none -vnc localhost:1 -daemonize  

  i tried with -nographics , -curses, -monitor stdio, pty and none, same result 
and with -serial as well
  tried </dev/null at the end of the command no luck same with & 

  my guess is that the keyboard and mouse gets grabbed by the "window"
  of the qemu regardless if there is graphics or not and i have not foud
  a "-headless" ,"-nograb" or "-nopussygrab" mode . (yeah had to make
  the joke :P)

  hardware:
  Z97N-wifi 
  Intel(R) Core(TM) i5-4690K CPU @ 3.50GHz
  ram > 8Gb
  keyboard is logitech
  mouse is logitech

  distro is suse leap 42.1 (made with suseStudio)
