[arch-general] unable to load virtualbox kernel module

I just installed virtualbox yesterday and I rebooted and can't load the kernel module. I reinstalled the package: $ sudo pacman -S virtualbox-host-modules

(1/1) reinstalling virtualbox-host-modules [######################] 100% In order to use the new version, reload all virtualbox modules manually. $ sudo insmod vboxdrv insmod: ERROR: could not load module vboxdrv: No such file or directory
