@karasu I don’t know if this helps but I am running Kernel 184.108.40.206
And after a recent fresh install I have Virtual-box 5.1.14 r112924 working by doing the following;
First use add/remove to install Qt5-x11extras
Then log in as root:
# pacman -S linux-headers
# pacman -S virtualbox virtualbox-guest-iso (Note; select - virtualbox-host-dkms)
# pacman -S vde2 net-tools virtualbox-ext-vnc
# modprobe vboxdrv
# nano /etc/modules-load.d/virtualbox.conf
Paste the following into the new file and presss CTRL + X + Y to save and exit.
Now add vboxuser to vboxusers group
# gpasswd -a yourname vboxusers
Now install the extensions pack from the Virtualbox website.
