Virtualbox gives me the following output:

Failed to open a session for the virtual machine 8.

The VM session was closed before any attempt to power it on.

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: SessionMachine
Interface: ISession {7844aa05-b02e-4cdd-a04f-ade4a762e6b7}

Try this:

  1. cd /home/$user/.VirtualBox/
  2. find the VirtualBox.xml-prev, which is a backup of the previous Virtual Box config 3.remove he current non-working config file rm VirtualBox.xml
  3. Use the previous working config file

mv VirtualBox.xml-prev VirtualBox.xml

Solved! I imported the virtual machine from a previous backup when I wiped the system clean. First I found out that the usb 2.0 configs were conflicting with virtualbox and after solving it I was prompted to install the Extension Pack. Done! May the force be with you.
