That's the correct behavior for now (see the test case, a prerequisite it
full screen), since when VirtualBox doesn't grab the keyboard, the unity
host gets the event and it will display the dash if needed.

Fine

Mh right... I actually think this is sane since the overlay should alway be
available when requested, since it doesn't need input and thus it doesn't
create any trouble.

Bug description:
  [Impact]
  After upgrading from Maverick to Natty, I can no longer use the Super (windows) key in Virtual Machine Manager. Previously, as long as I had the Virtual Machine Manager console window in the foreground, I could press the Super key and the start menu would pop up. Since upgrading to Natty, this no longer works, and the search box appears in the upper left.

  Also see bug #934921

  [Test Case]
  (1) Install virtualbox or virt-manager and qemu-system, create and boot a virtual machine
  (2) while in the virtual machine (and it should grab the keyboard), press the Super key
  Expected Result: the super key acts inside the VM (check by install unity on it or using xev)
  Buggy Result: the super key acts in the host and the Unity Dash is displayed

  [regression Potential]This patch plays with key grabs and ungrabs:
  the most likely potential for regression is (a) the existing grabs
  continue and no fix obtains or (2) the grab is not resumed when
  returning control from the VM and the Super key does not invoke the
  Unity Dash.
