Description of problem: I can set up a virtual machine entry, but when it comes time to start it, the daemon won't start. . The usual command returns [FAILED] dmesg has: VirtualBox[4836]: segfault at 128 ip b528a695 sp bffedbf0 error 4 in libQtNetwork.so.4.7.3[b51d9000+125000] Version-Release number of selected component (if applicable): 4.0.6_OSE How reproducible: Start a VM. Steps to Reproduce: 1. 2. 3.
Just to be sure, the system is fully up-to-date? as qt has been updated to 4.7.3 recently.

Yes I have all updates, which stopped a day or so ago, including all Qt4 packages now being 4.7.3. The error message mentions a Qt 4.7.3 file as being involved.
Yes, I noticed; just hoped it's an update issue.

I think you should file a bug report upstream, follow the instructions here: http://www.virtualbox.org/wiki/Bugtracker
Will do. There seems to be no similar bug reported.
Ticket #8879 filed with VirtualBox Bugtracker. http://www.virtualbox.org/ticket/8879#preview.
As at Sun 15 May 0400 UTC, after installing all updates, the VB daemon has started normally. I haven't changed anything specific to this bug.
Weird... but good outcome, of course....
Weird that nobody else reported it. I mentioned it on the Mandriva ng, and it seemed to be happening there as well. I wonder if there was an updated KDE library...
closing as it is working ( comment #9 )
Status: NEW => RESOLVEDCC: (none) => dmorganecResolution: (none) => FIXED
Yes, this bug seems to be fixed. After a re-install, the daemon won't start and there is nothing in dmesg. I suspect a leftover config file.
It started after I rebuilt the virtualbox kernel with dkms. My NVidia setup is in much the same position. Going to rebuild it next.
NVidia fixed as well. New bug against DKMS: 1311.

Manually you mean? the rebuild should happen automatically when you boot a new kernel for the first time (assuming the matching kernel-devel is installed).
Yes, manually. Rebuilt all 3 dkms modules (vboxdrv, vboxadditions, nvidia-current) manually. See Bug # 1311. Modules are being built automatically, and shown on the tree, but they don't work. At bug # 1311, I have included history from this bug.
I have two different installs and never had a problem like that with DKMS.... a possible scenario is you installed a kernel, then uninstalled it, then reinstalled it, that wouldn't have cleaned the dkms tree (the situation is better starting from kernel-2.6.38.6-1.mga1 as it removes the relevant /lib/modules/ dirs when removing a kernel)....
It didn't happen with my initial install. I don't recall uninstalling then reinstalling a kernel. I regularly install an update then uninstall the previous kernel, but so does everybody. Neither of these packages was part of the initial reinstall. The nvidia packages were installed with XFdrake, the VirtualBox with urpmi. I think that for a while I ran the system on the DVD before installing updates. The dkms files are in /var/lib and weren't deleted, while /usr was formatted. By removing the modules, I may have cleaned out /var/lib/dkms, but I don't know enough for that to be more than a guess. I suppose that I can wait to see what happens with the next kernel upgrade.
There may be something in what I just wrote. When I installed Virtualbox, there were messages that the modules already existed and needed to be removed first. They would have had to be in /var/ Normally, that doesn't cause any problem. I noticed that the command used included rpm-upgrade or similar, no doubt to get around that message.
My understanding is that the rpm package virtualbox-guest-additions should only be installed if Mageia has been installed as a guest under VirtualBox. It should not be installed on a host system, that will then be running VirtualBox.

Thanks for explaining that, Dave. Under Mandriva, I have always used the package from Oracle, and the guest additions are in fact installed on the guest OS. Surely the guest additions should match the host engine? But that is a side issue to the bug. I think that the answer to the bug was not cleaning out /var/lib/dkms There used to be a problem with MySQL caused by an existing log file in /var/log. I usually want to keep /var/lib/mysql and /var/www, so I don't format /var, but it would be good practice to do so.

(Thanks for the feedback).
