Virtualbox Manager 4.2.6 hangs when certain inaccessible VMs are present => fixed in SVN

Description

I've installed the latest Virtualbox (VirtualBox-4.2.6-82870-OSX.dmg) and the VirtualBox Manager opens and hangs (retrieving/populating the VM information?) and I need to force kill it!

Reverted to 4.2.2 and 4.2.4 and it works fine!

Do have the same problem after upgrading to 4.2.6 on Macbook ML, 100% cpu usage. Force kill and installed 4.2.4 (as before) everything normal

I have the exact same problem. I attached a file with some information.

comment:3 by kimus, 11 years ago

I must ask what more is needed for this issue has some kind of reply. This seams to be a seriously issue because we can't update to the latest release of VB and it's confirmed by other users but still no response from the devs.

I can help on whatever you need but please inform me what's relevant for understanding this issue and fix it or put in the road map.

comment:4 by Dsen, 11 years ago

I can't reproduce the issue on my mac host, so it is not easy to find/fix the reason without help of any user who is able to reproduce it.
Could any of you please provide me with the list of machines you have registered (through VBoxManage)?
It may be also helpful to know if Virtualbox Manager still hangs (or not) after you will unregister all the machines (through VBoxManage too).

The file with the hang stack information attached by qosobrin (virtualbox.txt) is not informative. We will probably check the stack trace of the debug build.

comment:5 by kimus, 11 years ago

Hi, thank you for your reply. I could help in what ever you need.

There's some feedback in this thread (page 2): https://forums.virtualbox.org/viewtopic.php?f=8&t=53225&start=15

But I could say that it hangs like this: http://cl.ly/image/3i224614190r (populating the VM information) but I can start VM by command line and even go to their settings after started.

comment:6 by Dsen, 11 years ago

There is a test debug build for Mac OS X (based on 4.2.7 version) available at:
http://www.virtualbox.org/download/testcase/VirtualBox-4.2.7-83123-OSX.dmg
Please note, this build should NOT be used as normal installation (its a test build to debug this issue).
If you wish to help us to find the reason of the hang, you can install this package (better to remove already installed before that) and run VirtualBox Manager in gdb in console terminal, then reproduce the full hang and then press "ctrl+c" (in console) to interrupt application execution in gdb, then call for back trace using "bt" command in gdb. Probably the call-stack will be helpful.

When I try to debug on my normal user I get:

 (gdb) run
 Starting program: /Applications/VirtualBox.app/Contents/MacOS/VirtualBox 
 Reading symbols for shared libraries +++................................... done
 VirtualBox: Error -10 in SUPR3HardenedMain!
 VirtualBox: Effective UID is not root (euid=501 egid=20 uid=501 gid=20)
 
 VirtualBox: Tip! It may help to reinstall VirtualBox.

When I try it with sudo or with the root user no VM's are in the VBManager list and no hang occurs.

Copied the VirtualBox settings from my user and the final result is:

comment:9 by Dsen, 11 years ago

Hmm, that stack is not informative too, without debug-symbols I seems can only guess what happens there. There are no links to actual GUI code, only base Qt classes. I will ask our build-engineers if it is possible to include debug-symbols (into test debug version).
From that I see its something with pixmaps caching stuff. Could you please try to reproduce the hang few times and check if it happens always on the same place? If the places are different, other stacks can probably enlighten the situation.
Also, just to clarify it for me, when the hang happens - GUI become fully non-responsible to mouse/keyboard interactions?
Thanks in advance.

comment:10 by kimus, 11 years ago

When it's retrieving/populating the VM information it starts to become very, very, very slow and then it stops and become non-resposible.

Another trace if I wait a bit more:

The last two traces looks more like GUI hangs on worker thread termination (thread which acquires information from VM).
Could you please check if the issue happens with just one newly created VM in VM list? (you can unregister all your VMs with VBoxManage for example and you can backup your configuration folder before that). May be thats some particular VM configuration causes the hang.

comment:13 by kimus, 11 years ago

Ok... found/workaround the problem!! :-)

I had an "<inaccessible>" VM. Removed from VirtualBox.xml and now VirtualBox Manager works fine!

EDIT: Also removed all "*.log*" files but I guess it was the "<inaccessible>" VM

comment:14 by Dsen, 11 years ago

Hmm, that is interesting.
I'm not able to reproduce the hang with inaccessible VM too. Indeed inaccessible VM handling even simpler than accessible one. So that makes issue even more strange. I hope you didn't removed that VM configuration file? Could you please provide me with .vbox from that VM folder? Also please check if returning back inaccessible VM declaration into VirtualBox.xml restores the hang behavior.
Thx in advance.

comment:15 by kimus, 11 years ago

I added:

<MachineEntry uuid="{642c2402-33da-4d25-871d-d2df044db6bd}" src="/Users/kimus/Virtual Machines/Windows XP/Windows XP.xml"/>

And it hangs again :-)

The VM folder does not exist! I have 2 VM groups (you can see it in the screenshot above) and this VM was inaccessible (was removed) and outside the groups.

comment:16 by Dsen, 11 years ago

Hi Kimus,
I can provide you with full debug trunk build with debug-symbols (to check the same as in comment 6).
Is it possible to discuss it with you in some irc-channel? For example we have external channel at irc.freenode.net (#vbox).

Host type: Mac OS Xall
Summary: Virtualbox Manager 4.2.6 hangs in Mac OS X ML 64bitVirtualbox Manager 4.2.6 hangs when certain inaccessible VMs are present

We finally found a way to reproduce. One needs a very special type of inaccessible VM to trigger a rather strange corner case which then leads to the API sending bogus events to the GUI, which re-trigger the strange API corner case. Effectively it's an endless loop in cooperation between the API (VBoxSVC) and the GUI.

Not host OS specific in any way.

Here is a test build of the upcoming next maintenance release of VirtualBox. Could you test if the bug is really fixed for you? Thank you!

Hi, I tested with the 4.2.7-83652 and worked fine.
