What vbox version are you running on the host? Now 5.2.4 r119785 (Qt5.6.2) on Win10 x64
Did you install the guest additions from the virtualbox website (or cd image) or from the kali repo? Kali Repo
What's the output of "dpkg -l virtualbox* | grep ^i" ? root@kali:~# dpkg -l virtualbox* | grep ^i
ii virtualbox-guest-dkms 5.2.4-dfsg-2 all x86 virtualization solution - guest addition module source for dkms
ii virtualbox-guest-utils 5.2.4-dfsg-2 amd64 x86 virtualization solution - non-X11 guest utilities
ii virtualbox-guest-x11 5.2.4-dfsg-2 amd64 x86 virtualization solution - X11 guest utilities
Have you tried upgrading the host to 5.2.4? Now on this version.
Are you using the vbox image from the kali site or did you install the guest from scratch? Install from scratch (kali-linux-2017.3-amd64.iso)
I've just tested the latest Kali in vbox on OpenSuSE (5.2.4), Windows (5.1.30 & 5.2.4) and Ubuntu (5.1.30) and they all work flawlessly.
