I've been trying to get VirtualBox installed through the CLI on my Slackware box. I ran the VirtualBox-4.3.6-91406-Linux_x86.run file and it successfully installed. Now when I try to run it, it gives me an error stating:

The vboxdrv kernel module is not loaded. Either there is no module available for the current kernel (3.10.17-smp) 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.
Failed to open the X11 display!

This is my first time doing anything like this. Is there anything I'm missing or something else that I need to install?

I think it is something like this:
cd /etc/rc.d
su (press enter and type the password for root)
./rc.vboxdrv setup (wait until the modules are built)
./rc.vboxdrv start
enjoy your VM =]

Another option could be to use http://slackbuilds.org/repository/14...ualbox-kernel/

IIRC the Vboxmodule is compiled during installation. It should also load when you boot up your machine. The message about "failed to open display" refers to the graphical user interface which can be started using "startx" from Runlevel 3 (the default in Slackware 14).

I'm sorta doing this from memory, but I've done it umpteen times, so I shan't be leading you too far off path, but a reboot is required in order to load the kernel module, plus you'll have to edit /etc/group and add users to vboxusers.

cheers,
