guest additions do not build with 4.11 kernel

[robatino]

Got an error message while attempting to install guest additions in a Fedora Rawhide guest for the 4.11.0-0.rc0.git2.1.fc26.x86_64 kernel.

vboxadd.sh: failed: Look at /var/log/vboxadd-install.log to find out what went wrong.

This is while using VBoxGuestAdditions_5.1.15-113518.iso, for which the 4.10 kernel guest additions do build successfully.

now I have this error :

Appears to work with VirtualBox 5.1.16. It wasn't clear whether it was fixed, the Changelog indicated that it was. I do see "vboxadd.sh: failed: modprobe vboxguest failed." in /var/log/VBoxGuestAdditions.log, but I think that line is always there, whether the GA build or not.

I'm not able to tell whether 4.10 builds, since I'm no longer using that kernel, but it was working earlier with the Test Build Guest Additions, so it should.

Fixed in VBox 5.1.16.
