Video display corrupts when using shared folders -> Fixed in 2.1.2

[Brian J. Murrell]

I have configured shared folders to work with my $host_os:~ however, whenever I try to access it from my WinXP Pro guest, within a few seconds of access, the video display of the guest will get corrupt. I have attached an example of this corruption. As soon as the display corrupts the VBox.log says:

00:01:23.286 Display::handleDisplayResize(): uScreenId = 0, pvVRAM=b22d0000 w=1312 h=890 bpp=0 cbLine=0x480
00:01:23.286 VBVA: Disabled.

Of course there is no actual display resize at this point. It was simply trying to access a shared folder. I will attach the VBox.log as well.

corrupted screen

Well, I was hoping to add the VBox.log file but when I try to "Attach File" I get an error:

TICKET_APPEND privileges are required to perform this operation

Hopefully the few lines above from the log that appear exactly when the corruption happens is enough. If not, please either fix the TICKET_APPEND problem or request the log from me by e-mail.

[Michael Thayer]

Try attaching the file again now. No idea why this didn't work in the first place.

VBox.log from session that corrupted the display

[Leslie Viljoen]

I have the same problem, thought it was fixed with this version but it seems not. I get the same thing when accessing SAMBA shares on my host machine: after a random (but normally short) interval, the display goes corrupt and mostly black. Sometimes there's a blue screen after that but mostly the machine is well frozen and I have to "ACPI off".

If I get the blue screen again I'll post the info it contains.

Yeah, other than I've never seen a BSOD from this problem, it sounds very familiar. It's interesting that it appears to be some kind of networking problem rather than shared folders or something.

If I get the blue screen again I'll post the info it contains.

Cool.

I see this too on VirtualBox 1.6.4 running Windows XP SP3.

To repro: Attempt to view My Network Places or navigate to a share directly in Windows Explorer by typing \<host>\<server> or \vboxsvr\<share> into the address bar.

I get the same display corruption and have to ACPI shut down my guest.

Yup, that is exactly my situation too. I wonder what we all have in common that others don't share.

Which host OS do you use?

If you use Windows, could you try to reproduce the problem with a debugger attached to the guest? If yes, I'll provide detailed instructions. Thanks.

[poulsbo]

My host OS is Mac 10.5.4. Please let me know if there is anything I can do to help debug this.

[poulsbo]

I uninstalled my Guest Additions, rebooted, reinstalled Guest Additions, rebooted, and now I have a different symptom, which I believe has been reported separately -- normal SMB networking works, but I cannot access \vboxsvr\<share>.

Ok this is back after a series of steps detailed in defect 1680 (​http://www.virtualbox.org/ticket/1680), basically, trying to get Shared Folders working using manually merged registry entries attached to that defect ticket.

[sunlover]

Please try the attached shared folders driver (ut the file to Windows\system32\drivers). Let me know whether it works. Thanks!

[Leslie Viljoen]

Wow, it actually seems to be working now! I have successfully messed around in shared directories longer than ever before without a crash, even running programs from those directories. The big test will be running the Visual Studio service pack - then I'll report back. Thanks so much for all your work on this, it really helps me a whole lot.

Crash after trying vboxsf.sys released 1 Sep 2008

[Leslie Viljoen]

Aw, it crashed now. I attached the bluescreen. I was just browsing my local SAMBA share, changing directories. My host OS is Ubuntu 8.04 (Linux lesliev-laptop 2.6.24-21-generic #1 SMP Mon Aug 25 17:32:09 UTC 2008 i686 GNU/Linux), my guest is Windows XP SP2. This crash is after I copied in the new VBoxSF.sys released 1 Sep 2008.

This looks similar to ​http://forums.virtualbox.org/viewtopic.php?t=2155&start=0&postdays=0&postorder=asc&highlight=mrxdav Could you try to disable the web client?

[Leslie Viljoen]

I disabled the web client and.... IT WORKS! I managed to run a detailed search on a shared drive, browse, install over the drive - even install Visual Studio 2005 SP1, which I have never been able to do in Virtual Box.

Thank-you very much!

I am noticing the same black screen with dots on Virtual Box version 2.0.0, but obviously the attached vboxsf.sys does not work. As such, this issue is unfixed.

Have you tried the driver attached to ​http://www.virtualbox.org/ticket/2055 ? The one from this defect will not work in 2.0.x.

Shared folders driver for VBox 1.6.x (updated)

[sunlover]

Should be fixed in 2.1.2.

[Erik]

Not certain if this bug is fixed. I've got 2.1.2 installed, and I've run into exactly this issue. If I navigate with explorer on an SMB share, the scree corrupts. However, if I navigate with the 'Run . . ' dialog, it doesn't corrupt the screen.

[sunlover]

Please attach VBox.log and provide some additional information:

1) Which guest/host is it? 32 or 64 bit?

2) You said you use a SMB share, is that right? Or do you use VBox shared folders actually?

3) Have you disabled the Web Client service in the guest?

Thanks.

[Frank Mehnert]

No response. Please reopen if you can provide more information. Especially, attach the VBox.log file of such a VM session.
