Everything you need to run virtual box should be in the repository already.
How did you install Virtualbox?
what ext packs do you mean most are in the virtualbox package?
Did you also install the host modules for your kernel series and turn on virtualization in your system UEFI/BIOS?
BIOS settings are correct and here is how I installed VB…
sudo pacman -S virtualbox
I then downloaded Ext Pack from Vbox site.
As for the other modules I took a chance and downloaded some through Octopi.
I went by info on Manjaro Wiki VirtualBox - Manjaro
The wirelss does work, but only once.
If you can advise best way to install VB, I would really appreciate it becuase the sound card (ASUS STX) is the best
reproduction I have ever heard in any OS, including Windows!
You only need the host module package for the kernel series your running it on like I listed above, please remove any other ones that you don’t need especially any guest modules for your kernel.
