[SOLVED] Virtualbox for Slackware Current 64

Gordie · 02-29-2016, 11:35 AM

I have just finished compiling and installing virtualbox from sbopkg.

So I view the help

bash-4.3$ virtualbox --help
WARNING: The vboxdrv kernel module is not loaded. Either there is no module
available for the current kernel (4.4.3) or it failed to
load. Please recompile the kernel module and install it by

sudo /sbin/rcvboxdrv setup

You will not be able to start VMs until this problem is fixed.

bash-4.3# /sbin/rcvboxdrv setup
bash: /sbin/rcvboxdrv: No such file or directory
bash-4.3#

Hmm, what to do now?

You also need to install virtualbox-kernel as stated in the README:
https://www.slackbuilds.org/reposito...em/virtualbox/

@All: please view the README before building a package using sbopkg, PLEASE.

PS but maybe you had virtulabox-kernel installed but didn't install a new module for the kernel new kernel (4.4.3), as the upgrade is recent.

I installed virtulabox-kernel and acpica first just like the readme says to do.

The virtualbox-kernel package is what creates the kernel modules. Are you sure it completed properly? Did you happen to build it for a different kernel than what you're now running (which shows it as 4.4.3)? Anytime you switch kernels, you need to rebuild that package, so it can compile the correct module for the correct kernel.

If you are sure you have the correct modules built from the virtualbox-kernel package, it may be that you didn't start the rc.vboxdrv service. In the README.SLACKWARE, it states you need to add /etc/rc.d/rc.vboxdrv start to your rc.local (and an additional one in rc.local_shutdown to stop the service). You would either need to reboot for that to start or start it manually using:

Code:

/etc/rc.d/rc.vboxdrv start

Once you do that, you should be able to start virtualbox (assuming you've added your user to the correct group).

Yes, but which kernel where you running then? If that was 4.4.2 you need to rebuild and install a virtualbox-kernel package for 4.4.3.

OK. Just recompiled and re-installed virtualbox-kernel from sbopkg. Rebooted. As root ran /etc/rc.d/rc.vboxdrv start and now all is OK

If you want to prevent needing to run /etc/rc.d/rc.vboxdrv start manually, the README.SLACKWARE states to put the following entry in your rc.local

Code:

	# Start vboxdrv
	if [ -x /etc/rc.d/rc.vboxdrv ]; then
	  /etc/rc.d/rc.vboxdrv start
	fi

And another entry in /etc/rc.d/rc.local_shutdown (you'll need to create it if you haven't before as it doesn't come with a stock Slackware install, even though support for it exists) to stop it when you shut down the computer.

Code:

	# Stop vboxdrv
	if [ -x /etc/rc.d/rc.vboxdrv ]; then
	  /etc/rc.d/rc.vboxdrv stop
	fi
