[Qemu-devel] [Bug 1502884] Re: Super important feature req: QEMU VNC server: Introduce a keyboard "norepeat" option!

What I request seems to be the same option as x11vnc's "-norepeat",

Title:
  Super important feature req: QEMU VNC server: Introduce a keyboard
  "norepeat" option!

Status in QEMU:
  New

Bug description:
  Hi,

  A big issue when using QEMU's VNC server (VNC KVM) is that, when
  there's a network lag, unintended keypresses go through to the QEMU
  guest VM.

  This is frequently "enter" keypresses, causing all kinds of unintended
  consequences in the VM. So basically it's extremely dangerous.

  This is because the VNC protocol's keyboard interaction is implemented
  in terms of key down - key up events, making the server's keyboard
  autorepeat kick in when it should not.

  
  For this reason, it would be great if QEMU's VNC server part would be 
enhanced with an option such that when a VNC protocol key down is received, 
then locally that is treated as one single keypress only (I don't know how that 
should be implemented but I guess either as an immediate key down - key up 
sequence locally, or key down + key up after say 0.05 seconds), instead of 
waiting for the key up event from the VNC client.

  Thanks!
