As @linux-aarhus has already pointed out:
These following instructions are repeated from the Manjaro Wiki VirtualBox article:
Make sure your kernel is supported:
mhwd-kernel -li
If it isn’t, then install one that is: Manjaro Kernels
1. If your kernel is 6.6.x for example (which it is), use 66
in the following command:
sudo pacman -Syu virtualbox linux66-virtualbox-host-modules
2. Reboot your system (important).
3. Start using VirtualBox:
sudo vboxreload
I hope this helps. Cheers.
→ Important: You will likely need to first undo all the things you’ve done during your previous attempts.
So, where is that output?
