vboxdrv causes kernel panic on SL 5.2

dweeks · Post by **dweeks** » 6. Oct 2008, 16:48

I have "Linux localhost.localdomain 2.6.18-92.1.6.el5xen #1 SMP Wed Jun 25 12:56:52 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux" which is SL 5.2. During the running of the install script for Vbox 2.0.2 for generic amd64 support, the kernel panics and reboots. This leaves me in a reboot loop because the vboxdrv kernel module is coring the system every time S30vboxdrv is run in rc.d. Might be something I am doing but I don't know what. Also, because this is a xen enable kernel, kdump is not available and the messages are lost.

First thing first -- can you get your host back up and running, or are you stuck in the reboot loop? If you know how to get to a command-line (boot CD, rescue disk, single-user-mode?) and prevent S30vboxdrv from running, let us know and we'll move on to the next step. If this post is because you are still in a reboot loop that will undoubtedly be your first priority.

Oh I did that. Probably should have said that. I got out of the reboot loop through single user mode. I also know from doing going into single user to do the modprobe of vboxdrv that it is causing the kernel panic.

Ok, I just did this with 1.6.6 with the same results.

For anyone else like me completely oblivious to what "SL 5.2" means, looks like this is it:

It seems to be based on Red Hat's Enterprise Linux.

Their most recent linux distribution is version 5.2 released in June 2008.

You can't run a virtualisation program inside a different virtualisation program. Either use Xen, or boot to a non-xen kernel. The kernel panic is because two applications want to have ring-0 and ring-1 access. That can't be done by two programs at the same time.

Ah, thanks. Is this in the FAQ? If so, I apologize for not looking harder.

Not in the FAQ (at least not the Forum one). I thought it was in the manual, but I am certain that one of the programmers mentioned this.

Yes that was it. Fixed. Thanks
