Virtualbox , Ubuntu 11.10 , linux-kernel 3: cannot start virtual machine

Solution 1:

Have you tried to build the kernel module?. It should have been builded during the installation, but it looks like it failed. You can try:

sudo dkms install virtualbox/4.1.2

This should build the module.

Solution 2:

Go to Dash and then software center and delete all virtualbox package...

Adding VirtualBox repository:

    sudo add-apt-repository "deb http://download.virtualbox.org/virtualbox/debian oneiric contrib"
    wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add -
    sudo apt-get update

Installing VirtualBox 4.1:

    sudo apt-get install virtualbox-4.1

If you want USB 2.0, VirtualBox RDP and PXE boot for Intel cards support on your guest machines, you have to install extension pack that can be downloaded here.

Installing extension pack

Once extension pack downloaded, open VirtualBox and navigate to "File -> Preferences", at the "Extensions" section, click icon "Add package" and locate your downloaded extension pack.

• What are PPAs and how do I use them?

Follow your petition :

sudo apt-get install kernel-package 
sudo apt-get install linux-source

Try removing the old module.

sudo apt-get remove virtualbox-ose-modules*
sudo apt-get purge virtualbox-ose-modules*

Then install the new one.

sudo apt-get install virtualbox-ose-modules-`uname -r`

and Try this

sudo /etc/init.d/vboxdrv setup

Solution 3:

I have no idea!, but I got the problem like you. I just tried to solve by install vbox version support on kernel version. it worked fine. I mean that if ur vbox version is 4.X.X support which is your os kernel version ( your computer). If you want check kernel version, go to terminal type: uname -s .
