VirtualBox : Fix "Spawning Session" problem

After installing some Ubuntu updates, I noticed that I couldn't start any Virtual Machine in Virtual Box.It shows a “spawning session” dialog which stuck at 0% forever.



Solution for the problem

If you can't close or terminate your VirtualBox program which is stuck with the 'Spawning Session' problem, just open the terminal and force kill the VirtualBox

• type sudo killall VirtualBox in the terminal

Now you need to recompile the kernel module for VirtualBox, It's not that hard

• just type sudo /etc/init.d/vboxdrv setup to recompile the kernel module and wait for a few seconds

You will get an output like the following

• * Stopping VirtualBox kernel module * done.
• * Removing old VirtualBox kernel module * done.
• * Recompiling VirtualBox kernel module * done.
• * Starting VirtualBox kernel module * done.

Now you can start playing with your virtual machines.
