def read_guest_additions_version
  # this way of checking for the GuestAdditionsVersion is taken from Vagrant's
  # `read_guest_additions_version` method introduced via
  # https://github.com/hashicorp/vagrant/commit/d8ff2cb5adca25d7eba2bdd334919770316c91be
  # for VirtualBox 4.2 and carries on for later versons until now
  # We are vendoring it here, since Vagrant uses it is only a fallback
  # for when `guestproperty` won't work. But `guestproperty` seems to be prone
  # to return incorrect values.
