Hello,
I installed Solus 4 Budgie in a VM with Virtualbox, and I installed virtualbox-guest-current, and it seems that vboxvideo is missing.
It allows the guest to resize/adapt the resolution depending of the host window.
I tried with the LTS kernel, and it's works fine.
The case of a current kernel does not seem to be properly handled by the virtualbox package
/lib/modules/4.9.166-128.lts/misc: vboxguest.ko vboxsf.ko vboxvideo.ko /lib/modules/5.0.5-113.current/misc: vboxsf.ko
vboxvideo is not missing, it's actually merged into the 5.0.5 kernel. Only LTS needs the out-of-tree module now.
Ah ok, I didn't know that
If it can help:

It allows the guest to resize/adapt the resolution depending of the host window.
This is a feature of the legacy graphic controller (VM created before virtualbox 6) that isn't available with VMSVGA
Yeah you just need to change the graphic controller to VBoxVGA and you might need to reinstall Solus, I'm not sure if you need to, you'll see after it's changed
Out of topic, does anyone knows why they decided to change this behavior ?
