boot up msg: VBoxClient: the VirtualBox kernel service is not running. Exiting

[gold_finger]

Two ways to remove the components.

GUI Method:

• Open Synaptic Package Manager (Menu -> System -> Install/Remove Software)
  
• Type "virtualbox" (no quotes) into the search box.
  
• Scroll through resulting list looking for the virtualbox ones that show as being installed.  (There will be three items.  See terminal command below for which three you should find.)
  
• Click on each one of them and choose "Mark for complete removal"
  
• Hit "Apply" button along top after selecting all three.
  
• Reboot and message should no longer be there.
  

Command Line (Terminal) Method:

• Open a terminal and enter this command to remove three virtualbox components:
  

Code:

sudo apt-get remove virtualbox-guest-dkms virtualbox-guest-utils virtualbox-guest-x11

• Reboot and message should be gone.
  

P.s.  If I had to guess, I think that virtualbox-guest-dkms is the one in particular causing the message.
