[Qemu-devel] [PATCH] input: send kbd+mouse events only to running guests.

[Gerd Hoffmann]

Trying to interact with a stopped guest will queue up the events,
then send them all at once when the guest continues running, with
a high chance to have them cause unwanted actions.

Avoid that by only injecting the input events only when the guest
is in running state.
