I previously was using VirtualBox on Fedora 30, but recently moved to using Boxes (review) and am quite happy with the switch. I've removed VirtualBox, but upon booting up my system, I still get a tainted kernel message:

vboxdrv: module verification failed: signature and/or required key missing - tainting kernel

I've tried:

sudo rmmod vboxpci vboxnetadp vboxnetflt vboxdrv

(the other modules were being used by vboxdrv)

This appeared to remove the module, but after a reboot, the modules were back.

Since I am no longer using VirtualBox, how can I remove this vboxdrv kernel module?

Thank you for any help!

Caveat: I don't have a Fedora system at-hand, so this is untested!

I would suggest removing the file /etc/modules-load.d/virtualbox.conf; it may be owned by a package, so check: dnf provides /etc/modules-load.d/virtualbox.conf and if needed, remove that package with: dnf remove (that package name).

As per this Fedora Forum post, you may need to rebuild your initramfs so that it's built without the vbox driver(s). Use: dracut -f /boot/initramfs-"$(uname -r)".img "$(uname -r)"

Specific solution from the OP:

I found virtualbox.conf located in /lib/modules-load.d/ and provided by VirtualBox-server. After removing VirtualBox-server, then removing vboxpci, vboxnetadp, vboxnetflt, and vboxdrv via rmmod, and finally rebuilding initramfs as written above, the problem is solved.
