If you have any suggestion, feel free to contact me via social media or email. MoreĬheck Arch Wiki for more info about the installation and VirtualBox usage. Therefore, if you are not using the latest kernel, your current kernel will not load the modules. VirtualBox downloads required kernel modules in a folder whose name is the latest kernel version (e.g.: /lib/modules/5.15.5-arch1-1/) and the kernel only looks for modules inside a folder with its current version (e.g.: /lib/modules/5.15.2-arch1-1/).

If, when you go to start a new VM, VirtualBox shows an error about a not loaded module, check if you are using the latest kernel (check if there are updates for the linux package in pacman and update if needed). Inside the VM, open your mounted CD-ROM device, open a terminal in that folder (if it is a Linux VM) and type (as root): bash.Go to /usr/lib/virtualbox/additions/ and select VBoxGuestAdditions.iso. In your running VirtualBox VM window, press on Devices -> Optical Drives -> Choose a disk file.Install virtualbox-guest-iso on your Arch machine.For any other kernel ( linux-lts, linux-zen, linux-hardened, etc.), select virtualbox-host-dkms. It will ask you which VirtualBox kernel modules you want to install: if your device has the default kernel ( linux), select virtualbox-host-modules-arch.
