VirtualBox

[chsims1]

For those of you using virtualbox out there, have you come across this problem? Everything seems to emerge OK, but when I try & run the program, I get:

Code: Select all

Error: vboxdrv kernel module is not loaded...
Please load the module before starting VirtualBox.

If I then modprobe vboxdrv I get the following error.

Code: Select all

FATAL: Module vboxdrv not found.

Looking on other forums, the only advice offered was "depmod -a", but this does not remedy the problem in my case.

I have tried emerging both virtualbox & virtualbox-bin, but the error is the same in each case.

Any ideas please?

Hi

Are you sure that you have emerged virtualbox-modules. That's the package that contains the vboxdrv module?

I use virtualbox svn version on SL3.30 64-bit and everything runs fine here.

Cheers

yep, virtualbox-modules is installed too.

Hi

Just remembered another thing you have to do.
If you open the file /boot/grub/grub.conf

You need to add nmi_watchdog=0 to the end of the line that starts kernel.

Reboot the machine and try to load the module again.

Cheers

Thanks for the reply Dave, but still no joy ..... what does nmi_watchdog=0 do anyway?

One of the things which mystifies me as a SL/Gentoo newbie is how apparently doing the same thing (emerge blah_blah) produces such different results on different PCs. Especially with emerging binaries. Oh well, it's all a learning process, if a little frustrating at times.

Hi

What version of Sabayon are you using? i.e. the mini or DVD versions?

Cheers

Dave

[chsims1]

Mini .... am I likely to be missing some essential package/s?

emerge virtualbox-bin

should install 3 packages I believe -verify they are installed

With a bit more fiddling I notice that the virtualbox-modules uses a gentoo kernel source during compilation:

Code: Select all

Found sources for kernel version:
 *     2.6.20-gentoo-r4
>>> Unpacking source...

>>> /lib/modules/2.6.20-gentoo-r4/misc/vboxdrv.ko


Now, my kernel from uname -r is 2.6.20-sabayon-r3 .... presumably this is the problem, but what is the solution? The gentoo-r4 appears from when I was trying to recompile my kernel a few days ago & I managed to end up with that one somehow. I recompiled correctly, and as I said above is reported as sabayon-r3 now. So, do I simply remove the gentoo-r4 files, or is this going to get me into deep trouble?

[wolfden]

check your kernel you are actually using -

Code: Select all

uname -r

than see what kernel u are set to

Code: Select all

eselect kernel list

if the * is on the wrong kernel change it to the right one

Code: Select all

eselect kernel set 1

or whatever the number is for your kernel than recompile
