Control-Break not passed through to Windows guest on Linux host => Fixed in SVN/3.1.4

[SeijiSensei]

I added this to bug 1062, but I'm concerned it will be ignored since that bug report is very old.

The problem is that the Ctrl-Break keyboard command is not passed through to the Windows guest when running on a Linux host. Not passing through the Ctrl-Break combination means that some programs like MS Access cannot be controlled as expected. In the case of Access, the break command stops execution of a query. Without this command, there is no other option for dealing with a hung or run-away DB query other than closing the entire VM. (Access does not let you close it while a query is being executed.)

I'm using 3.1.2 r56127 installed from the .deb onto Kubuntu 9.04. I'm running Win7 in the guest with the Guest Extensions enabled.

Hmm, is the a small test application which can prove that the CTRL+BREAK is not passed to the guest? I've checked this with a Linux guest on a Linux host and it seems that the Linux guest can see the same key sequence as the Linux host. You didn't try to press RightCtrl+Break when RightCtrl is assigned as host key, did you?

[Frank Mehnert]

I take my previous comment back. Problem confirmed.

[Frank Mehnert]

Problem will be fixed in the final release of VBox 3.1.4.

Great news, Frank. Thanks for the quick reply!

Hi. This is my first post so let me know if I am not supposed to be reopening this ticket. I was having the same issue as reported in this bug except I was am using an OpenSolaris host. I upgraded to 3.1.4 and I am still unable to issue a CTRL-Break to my windows guest.

Here are the details:

Virtual Box: 3.1.4 - Build 57640 Host: OpenSolaris Build 132 Guest: Windows XP SP2 Application - Lotus Notes Version 6.5.6 - Using CTRL-Break in this application is supposed to cancel current activity but this does not work.

Thanks.

Replying to frank:

Fixed confirmed for MS Access 2007 running in Win7 Guest on Linux Host,

VirtualBox: Version 3.1.4 r57640 with Guest Extensions Linux: 2.6.31-16-generic Ubuntu SMP x86_64 Windows: Windows 7

Thanks again, Frank!

tristin69: Which VBox frontend are you using, the normal GUI? Actually we tested the fix only on a Linux host, not on Solaris.

[Frank Mehnert]

tristin69, can you do the following? Please start /usr/X11/bin/xev on your Solaris host (from an X11 text console), move the mouse over the new X11 window then press Pause, then Ctrl+Pause, then terminate the application. Please attach the output of xev to this defect. Thank you!

I experience the same problem with a linux host (Version 3.2.6 on OpenSUSE) and a Windows XP Professional guest.

The corresponding xev output:

I experience the same problem with a linux host (Version 3.2.8r64453 on Ubuntu 10.04) and a Windows XP Professional SP3 guest.

Right, the fix for Linux hosts got somehow lost in VBox 3.2.0. VBox 3.2.10 will have it again, thanks for the report.
