Title: vbguest error workaround.

It is fixed to avoid a problem in the vbguest is one of the popular plug-ins.

An ad hoc basis, this is not a good patch, but because they are not such as side effects, please use if there is a need.

(Because CoreOS does not require any VirtualBox Guest Addtions As I understand it)
