#5375 closed defect (fixed)

Long continuing keypress freezes WindowsXp-Host => Fixed in SVN

Reported by: Karsten Steingaß Owned by:
Component: other Version: VirtualBox 3.1.0
Keywords: Keystroke Cc:
Guest type: Windows Host type: Linux

Description (last modified by Frank Mehnert)


If I press a key on the keyboard for a very long time the input devices and maybe the whole system freezes until the key is released.

I first encountered this while "walking" in a 3D video game, where this bug also results in a Network-Lag but it not only happens in games it also can be reproduced on the Desktop.

The guest OS here is Windows XP with SP3, with a 2 CPU host and guest.

Steps to reproduce:

  1. Create new empty textfile
  2. Press a character key
  3. Move the mouse several times in a slow/normal speed from edge to edge (while the key is still pressed)

Expected results: Character is written to text file endlessly and mouse cursor moves over the screen.

Real result: Mouse and Screen freezes until the key press is released.

The mouse move only hastens the thing, it also happens without mouse but than it takes way longer. I normally manage to get two freezes before the character hits the border, sometimes only one.

If you need additional information , I'm glad to help as good as I can.

Bye, Karsten

Updated to VBox 3.1.0

I am able to reproduce it here, according to your steps.

Host1: RHEL 5.3/x64, Core 2 P8600, VBox 3.1.0. (reproducible here)

Host2: Windows 7, x64, Core 2 Q6600, VBox 3.1.0. (non-reproducible here)

Guest: Windows XP.

It happens both with UP and SMP VM. (ACPI, ACPI SMP and even Standard PC HALs in XP)

Strangely enough, it does not happen on Windows Hosts !

Confirmed using a Windows XP guest and on a Debian / Lenny host. Most probably a bug in the PS/2 mouse/keyboard emulation.

I've missed this report bug confirmed for Windows XP SP3 32 bit host, #6249

comment:4 by Mihai Hanor, 14 years ago

the issue is present in VB 3.1.6, host&guest XP SP3 32 bit
just open Notepad, start pressing a letter key and while keeping it pressed, move the mouse cursor inside the guest (mouse integration can be enabled or disabled)

We think we finally fixed this bug. The fix will be available with the next release of VBox.
