Description
I'm using Xubuntu 18.04 LTS as VM Guest (VirtualBox 6.1.28, I've tried with 6.1.30 also, Windows 10 Host).
If I'm using standard Linux kernels (4.x or 5.x), I'm able to install VirtualBox Guest Addition using the sudo ./autorun.sh command from the ISO mounted folder. No issue, working perfectly.
But If I'm using Linux Preempt RT Kernel, impossible to install VirtualBox Guest Addition. I've tried with Kernel 4.16.12-RT5, 5.14-RT19, 5.15.2-RT9. As a result, no shared folder, no mouse... I've correctly compiled and installed linux-headers and linux-image corresponding to each Preempt RT kernel which are working correctly in standard PC. The linux distribution is up to date using the sudo apt-get update, sudo apt-get upgrade, sudo apt-get dist-upgrade commands. I've tried also to install virtualbox-dkms, dkms and virtualbox-guest-utils without any better result
It seems that the Virtualbox Guest Addition is not able to use to dedicated Preempt RT headers, even if they are set in linux kernel installation.
Please see the attached log for explanation.
