I am running OPENSTEP 4.2 with Oracle VirtualBox 6.1 on Debian 11.

Everything works great, but I have one smallish problem, the mouse support is kind of wonky.
The mouse pointer stutters quite a bit , not enough to be terrible but it is annoying.  I have PS/2 mouse
selected in VirtualBox. I tried adjusting mouse speed in OPENSTEP, but it just makes it worse.

I have also thought about switching to QEMU but I am not sure if that will be better.

PS/2 mouse support seems to be a bit problematic in OPENSTEP - I had a problem with a stuttering mouse cursor running on early qemu versions. I wrote a bus mouse emulation for ancient qemu in 2005. Amazingly, my original accouncement of the patch can still be found online.

It seems that there is sample code for a VirtualBox extension that emulates a bus mouse. Maybe this is an alternative worth trying? Beware, I never tried compiling or using that extension.

Hallo @wizard , you are using a very similar environment to mine.

Not sure if my mouse config would be good enough for your purposes, but for me it works smooth and usable enough.

Please have a look into the following screenshots of Preferences and Devices to find my settings and the extra mouse preferences package I am using.

... and here the final picture of the preference package name GKMouseScaler, with which you can fine-tune all acceleration levels of the mouse movement:
