Using RDP crashes the VM

[dusty]

I created a guest Windows XP vm running on a host linux-2.6.26 64bit (Debian Lenny).

If I use the VM via RDP from a windows XP client after a few minutes the connection hangs or crashes and so does the vm. I've not yet reproducted the problem using rdesktop but maybe because I've not used it enough time.

Please attach VBox.log from the crashing session to this ticket (from ~/.VirtualBox/Machines/name_of_your_XP_vm/Logs).

[dusty]

Here it is the attach. The server was started this way: VBoxHeadless -s name &

[sunlover]

Thanks but are you sure that the log is from a crashed VM? I'm asking because you said "after a few minutes the connection hangs or crashes and so does the vm" but the log ends with "01:30:32.625 Guest Log: VBOXNP: DLL unloaded." which is more than an hour later than the last RDP client connection (at 00:08:41.492).

BTW, what do you do in the guest when the crash happens?

Could you provide a core dump of the crashed VboxHeadless?

[dusty]

Actually I'm unsure at all but I found those logs in the specified folder. Do I need to enable some options to create log files and/or dumps?

[sunlover]

You can delete all VBox.* files from the /Logs directory and then reproduce the problem and attach the new VBox.log to this ticket.

Information about core dumps can be found in ​http://www.virtualbox.org/wiki/Core_dump

Also after you get the new log of a core dump for a VBox crash, please describe what lead to the crash. For example, browsing a shared folders in Windows Explorer, or opening a Web page in a web browser, etc.

Here it goes a new crash, but no log file has been created, maybe this is the behavior when started with VBoxHeadless.

I try now to start the vm with VBoxManage startvm

[sunlover]

The log file is created always. If the VM was started, the log file should be there too. A lot of information is written to the log even before the guest starts. May be you have looked at a wrong Logs directory?

When connecting with the rdp client in microsoft xp I very often get a crashed VM after disconnecting. The logs always end like this:

10:33:49.296 VRDP: Connection closed: 10:33:54.334 VRDP: DisableStatus timed out 5000!!! 10:33:54.334 VRDP: Logoff: MBP (xx.xx.xx.xx) build 6001. User: [theuser] Domain: [] Reason 0x0001. 10:33:54.376 VBVA: VRDP acceleration has been disabled.

I have two clients using XP that crash the VM's all the time. I have never seen a crash from the client using rdesktop 1.6.

This is on debian lenny with VB 2.1.4

Have not yet tried 2.2.0

Fixed formatting.

10:33:49.296 VRDP: Connection closed: 
10:33:54.334 VRDP: DisableStatus timed out 5000!!! 
10:33:54.334 VRDP: Logoff: MBP (xx.xx.xx.xx) build 6001. User: [theuser] Domain: [] Reason 0x0001. 
10:33:54.376 VBVA: VRDP acceleration has been disabled. 

Also attaching output from vboxheadless.

This problem can only be debugging if you submit a core dump, see sunlovers comment above. If you have a core dump, feel free to contact me directly via private E-mail at frank _dot_ mehnert _at_ sun _dot_ com.

[Frank Mehnert]

We've analyzed the core dumps but so far did not found the reason for the crash yet. Have you tried if VirtualBox 3.0.6 Beta 1 has the same problem?

[dusty]

I've been unable to replicate it on 3.0.4, if you prefer we can close the bug report and I'll reopen it in case something new shows up

[Frank Mehnert]

Ok, in that case I will close this bug. Thanks for the feedback.
