• Follow a "start the VM from cold-boot" / "observe error" / "shutdown the VM" cycle.

• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".

• Save only the first "VBox.log", ZIP it and attach it to your response.

• You were supposed to follow these steps when you filed the bug:

  Attach a (full) log file ("Machine" menu/"Show Log" in the main VirtualBox Manager window) straight away to save time for you and for us. The log file contains a lot of useful information about both the host and the guest systems as well as information about what happened during a particular machine run. Please do not cut and paste it.
