I am using Manjaro version
Linux XXXX-manjaro 5.9.8-2-MANJARO #1 SMP PREEMPT Wed Nov 18 06:38:03 UTC 2020 x86_64 GNU/Linux
I tried to install virtual box and it got installed using the below steps
sudo pacman -S virtualbox
Then i tried to load the kernel module
sudo pacman -S linux59-virtualbox-host-modules – I hope this is the right module
sudo modprobe vboxdrv
Getting error as modprobe: FATAL: Module vboxdrv not found in directory /lib/modules/5.9.8-2-MANJARO
Need your assistance on the same
@tuxmanjarino _ I tried that link but the kernel version was 5.4 in the document and they loaded linux54-virtualbox-host-modules but for version 5.9 not sure which version of hostmodules to load
It clearly states:
To install VirtualBox, you need to install the packages
virtualboxandlinux*-virtualbox-host-modules. The latter must match the version of the kernel you are running.
yeah i tried to install sudo pacman -S linux59-virtualbox-host-modules following my version 5.9 but getting as error if i try to do vboxreload
Why not simply reboot the system? 
Hi @bogdancovaciu did a reboot and tried the command but getting failed to load the module again, what else do i need to check ?
$ sudo modprobe vboxdrv [12:42:26]
[sudo] password for sampath:
modprobe: FATAL: Module vboxdrv not found in directory /lib/modules/5.9.11-3-MANJARO
FAIL: 1
Ok, this is not quite consistent and i don’t know how you do the updates and the installation. This is what should make things work:
sudo pacman-mirrors -f5 && sudo pacman -Scc && sudo pacman -Syyu virtualbox virtualbox-guest-iso linux59-virtualbox-host-modules
Reboot after that.
I had the same problem! The error is happening because you installed virtualbox before installing the kernel headers. Even though your virtualbox installation is fine, the kernel modules were not built.
A easy solution would be reinstall virtualbox after installing the kernel header. This will make sure that virtualbox kernel modules are build against your kernel
Also remember you’ll be needing community/virtualbox-host-dkms for host kernel modules
@bogdancovaciu - It is working now. Thankyou so much for your assistance . I could able to load the module. Works like charm !
Is this not something a package manager should solve (pull in the necessary dependencies) ?
Wiki says $ sudo pacman -Syu virtualbox [etc…], OP was on an old kernel and did sudo pacman -S virtualbox .
Well not exactly. Dealing with things like kernel headers is not that straight forward. Mainly because you can’t always be sure which Kernel the user is running. This is why applications that need to use kernel headers require manual installations of the kernel headers
