This is still an issue, I am not sure which precise set of functionalities
it impairs in VirtualBox.

I experience the same problem on a fresh 11.1-RELEASE install on amd64:

  $ uname -a
  FreeBSD llea 11.1-RELEASE FreeBSD 11.1-RELEASE #0 r321309: Fri Jul 21
02:08:28 UTC 2017     root at releng2.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC
 amd64


The symptom is the same for me as reported by palik:

  $ sudo service vboxservice forcestart
  Starting vboxservice.
  VBoxService: error: VbglR3Init failed with rc=VERR_FILE_NOT_FOUND

It is possible to trace the error the condition to the VboxGuestR3Lib.cpp
file in the sources as a hint that the file VBOXGUEST_DEVICE_NAME cannot
be opened.  I believe this is the matching definition for FreeBSD

  include/VBox/VBoxGuest.h:# define VBOXGUEST_DEVICE_NAME         
"/dev/vboxguest"

and I actually do not have a /dev/vboxguest file on my system, while the
kernel module with the same name is loaded.


The sources

  src/VBox/GuestHost/OpenGL/util/vboxhgsmi.c

also led me to think that this device might be created by the graphic
stack of VirtualBox.  I therefore rebuilt virtualbox-ose-additions
from the branch 2017Q4 of the ports tree, enabling the support for
OpenGL, but this did not change the situation in any visible way.
