[Qemu-devel] [Bug 1654826] Re: Holding key down using input-linux freezes guest

[mutedbytes]

I have tried without "repeat=on" option, and with 2.8.0 I still seem to
be getting weird behavior with mouse dropping out at points, and with
keys seemingly being continued to be pressed (ie still running around in
an fps game after releasing the key). I also experienced at one point
l-ctrl+r-ctrl not passing keyboard control to guest, and needed to VNC
in to shutdown/restart guest (this was after plugging in a usb xbox360
controller, not sure if related).

Title:
  Holding key down using input-linux freezes guest

Status in QEMU:
  New

Bug description:
  Qemu release version 2.8.0
  KVM, kernel 4.9.1

  When using the -object input-linux capability in qemu for passthrough
  of input/evdev devices, I found that when a key is held for a few
  seconds or more (such as ctrl key), the guest system freezes until the
  key is released. In some cases, mouse control is also lost following
  one of these "freezes". I also noticed that one of the four cpu cores
  I have the guest pinned to ramps to 100% during these freezes.
