modprobe vboxdrv failed

Post by benke »

Hi all.

Sorry for bothering you but I just downloaded VirtualBox-2.0.0-36011-Linux_x86.run but having problem with kernel module. When I issue /etc/rc.d/rc.vboxdrv setup it says

Code: Select all

Stopping VirtualBox kernel module ...done.
Removing old VirtualBox kernel module ...done.
Recompiling VirtualBox kernel module ...done.
Starting VirtualBox kernel module ...failed!
  (modprobe vboxdrv failed. Please use 'dmesg' to find out why)
The last line got with dmesg is

Code: Select all

vboxdrv: Unknown symbol register_cpu_notifier
If I try to start VirtualBox, I get this message:

Code: Select all

WARNING: The vboxdrv kernel module is not loaded. Either there is no module
         available for the current kernel (2.6.20.3) or it failed to
         load. Please recompile the kernel module and install it by

           sudo /etc/init.d/vboxdrv setup

         You will not be able to start VMs until this problem is fixed.
I am using VectorLinux 5.8, kernel is 2.6.20.3. Thank you in advance.

I assume you didn't have a previous version of VB running, else there might be some residual config that is causing this problem. Have you already tried a reboot? If you don't really need the added features of 2.0, use the maintenance release 1.6.6 instead.

Thank you for fast reply.

No, I didn't had previous version running. I uninstalled 2.0.0 and now I am downloading 1.6.6...

CPU is Sempron 2500, VectorLinux 5.8 is 32 bit distribution, gcc is installed and kernel source version is same as kernel - 2.6.20.3. vboxdrv goes to /etc/rc.d (it's Slackware-like):

/etc/rc.d/rc.vboxdrv setup

1.6.6 works, with lsmod I can see that module is loaded...

Dont know Vector Linux. For Suse there is a package called "kernel-syms" needed.

Probably here failing something like that?

register_cpu_notifier is part of the SMP support in the Linux kernel. I guess that this is missing from the VectorLinux 2.6.20 kernel. Well as long as 1.6.6 works.

VirtualBox 3.0.0 works under VectorLinux 6.0 which works under VirtualBox 1.6.6 under VectorLinux 5.8 :D

Looks like it's time for OS upgrade...

Benke, Starting VB is one thing, running a VM will really test the module and you can't do that inside a VM (nested won't work). Did you run the command the TS used?

Gosh, I am not sure that I would get any work done with the distraction of that desktop :lol:

As S says, installing and running the VirtualBox GUI is one thing. Running a nested VM is entirely another. If that works I'd be surprised and interested to know.

Okay, will try to run Slax, Puppy or something like this to be sure that it really works. Thanks for pointing me but kernel module is loaded...
