Virtualbox archlinux notes

archlinux-virtualbox.sh

# sudo /sbin/rcvboxdrv -h
# Unloading modules: 
# Loading modules: modprobe: FATAL: Module vboxnetadp not found in directory /lib/modules/4.4.3-1-ARCH
# modprobe: FATAL: Module vboxnetflt not found in directory /lib/modules/4.4.3-1-ARCH
# modprobe: FATAL: Module vboxpci not found in directory /lib/modules/4.4.3-1-ARCH
# modprobe: FATAL: Module vboxdrv not found in directory /lib/modules/4.4.3-1-ARCH

# Solution
# from https://forum.antergos.com/topic/818/can-t-run-my-vitualbox/4

pacman -Si linux
sudo pacman -S linux-headers
# will install DKMS properly
sudo pacman -S virtualbox virtualbox-guest-iso

# now this command should work :)
sudo modprobe -a vboxdrv vboxnetflt vboxpci vboxnetadp

# you may run this
sudo /sbin/rcvboxdrv -h

# add current user to vboxusers group
sudo gpasswd -a $USER vboxusers

# now add entries to /etc/modules-load.d/virtualbox.conf
# for startup
vim /etc/modules-load.d/virtualbox.conf
# insert this:
#vboxdrv
#vboxnetadp
#vboxnetflt
#vboxpci

# Module vboxdrv not found in directory /lib/modules/5.15.72-1-lts

# Module vboxdrv not found in directory /lib/modules/5.15.72-1-lts

In my case I needed to run this:

yay -Syyu
yay -Sy virtualbox-host-dkms virtualbox virtualbox-guest-iso linux-lts-headers

sudo modprobe -a vboxdrv vboxnetflt vboxnetadp

sudo gpasswd -a $USER vboxusers

sudo su
touch /etc/modules-load.d/virtualbox.conf
echo vboxdrv >> /etc/modules-load.d/virtualbox.conf
echo vboxnetadp >> /etc/modules-load.d/virtualbox.conf
echo vboxnetflt >> /etc/modules-load.d/virtualbox.conf

For me, how I'm using linux-lts kernel, I followed the arch linux guide and installed the linux-lts-headers instead of linux-headers.

So @KenEkanem, if you still can't solve it, try this way, maybe it can help you.
note: You can change yay by pacman

And @GabLeRoux, thank you so much, your guide helped me a lot 😊

What worked for me was doing a full system upgrade and then installing linux-lts-headers, then I went over to BIOS and enabled Intel (R) virtualization technology. thanks @Dpbm
