Slackware 14.0, 32-bit host no EFI: modprobe vboxdrv failed

Post by mik3ca »

I have a problem with VirtualBox.

I installed the latest one that would work with a 32-bit PC.

When I run the installer, it wants to execute vboxconfig, but everytime it does, I see the following:
vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: failed: modprobe vboxdrv failed. Please use 'dmesg' to find out why.

There were problems setting up VirtualBox. To re-start the set-up process, run
/sbin/vboxconfig
as root. If your system is using EFI Secure Boot you may need to sign the
kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before you can load
them. Please see your Linux system's documentation for more information.
I get nothing when I execute dmesg and I searched everywhere for vboxdrv, vboxnetflt, vboxnetadp, vboxpci as modules and could not find any.

Why do I get this error?

I decided to compile the contents of /opt/VirtualBox/src by executing "make" and "make install"

then when I executed "insmod vboxdrv.ko" This error pops up:
Error: could not insert module vboxdrv.ko: Invalid module format
Then when I execute dmesg, I get:
vboxdrv: version magic '3.2.29-smp SMP mod_unload PENTIUMIII ' should be '3.2.29 mod_unload 486 '
Why should the version magic thing be happening?

and this is what I get when I execute "uname -a"
Linux localhost 3.2.29 #2 Mon Sep 17 14:10:59 CDT 2012 i686 Intel(R) Pentium(R) M processor 1.60GHz GenuineIntel GNU/Linux

Please clarify the version number? Also from Official Virtualbox.org (supported here) or from Slackware's repository (not supported here)?

There are prerequisites for official Virtualbox https://www.virtualbox.org/manual/ch02. ... nux-prereq
