Thought I might add:
The qemu command line option equivalents for mouse and keyboard:
-object
input-linux,id=kbd,evdev=/dev/input/by-path/platform-i8042-serio-0-event-kbd,repeat=on,grab_all=on
\
-object
input-linux,id=ms1,evdev=/dev/input/by-id/usb-ROCCAT_ROCCAT_Kone_Pure-event-mouse

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.
