Virtualbox not working

I’m sure you did but is case did you reboot after reinstalling and is your system fully up to date.

I have never installed VBox from Oracle.
I install it from rpmfusion and then it has always “just worked”. The kernel modules are built with akmods and load with no issues.

Remember that to avoid potential conflicts you have to properly remove all traces of VBox from the oracle install, including having already removed the vboxdrv module from the kernel, before installing the one from rpmfusion.

Yes i have and yes it is :slight_smile:

24

Can you tell me what and where are all these traces are located in the Filesystem. Maybe i had to remove these manually

Thnx

Have you made sure to add yourself to the vboxusers with
usermod -a -G vboxusers username
username being you the user

Yes, I am a member of the vboxusers group. My VBox worked well until before the update to F38. I just tried to install the Oracle version again, so the suspicion that there are still remnants of this installation in the system could be correct. I just don’t know what else I could delete manually to install a clean rpmfusion version.

As I posted earlier I was having the same issue.I uninstalled vbox with dnf remove virtualbox-7.0 then installed it from rpmfusion.I have not had any issues since.

28

I can actually reproduce the issue using the RPM Fusion repos.
But it loads the modules correctly when installed from the Oracle repo and patched by the RPM Fusion patch like this:

sudo dnf remove VirtualBox\*
sudo reboot

sudo dnf install VirtualBox-7.0 kernel-devel patch
curl -L https://pkgs.rpmfusion.org/cgit/free/\
VirtualBox-kmod.git/plain/kernel-6.4.10.patch \
| sudo patch -f /usr/share/virtualbox/src/\
vboxhost/vboxnetflt/linux/VBoxNetFlt-linux.c
sudo vboxconfig

Great, it seems my VBox-Installation works again. Have i to Patch the Kernel on each Kernelupdate?

Only upgrading VirtualBox requires to re-apply the patch, unless they break something else in the newer kernels that would require a different patch, or they can merge it upstream eliminating the need for manual patching.

This means that kernel-6.4.10.patch seems to work with 6.4.14 also.
Thank you very much :+1:
