To sign kernel modules to make work with secure boot, this 2 posts are a good reference, I haven't test my self: It happens when secure boot is enable and so far we can run it with secure boot enabled because kernel modules still not signed Modprobe: ERROR: could not insert 'vboxdrv': Key was rejected by service Starting in Fedora 36 secureboot is supported by akmods please read /usr/share/doc/akmods/cureboot (from akmods package) for more details Sign kernel modules to work with secure boot Please do not add anyone who is not trustworthy to the vboxusers group! Once a user is in the vboxusers group, it may have ways to get root access. As a result may runs some parts of its code with root privileges. Note: USB passthrough requires read/write access to USB devices. Usermod -a -G vboxusers username ( usermod -a -G vboxusers sergiomb ) To have access to USB passthrough, you need add the user that run VirtualBox-server to vboxusers group, but just after installation of VirtualBox-server package, because VirtualBox-server creates the 'vboxusers' group on installation. Please do: dnf install VirtualBox kernel-devel-$(uname -r) akmod-VirtualBoxįirst time installation and USB passthrough Since F22+ we don't have pre-built kmods we need use akmods. The goal is have a place with all information that is FAQ. Install virtual-guest-additions on Centos 9 (stream).Uninstall official virtual-guest-additions provide by Oracle and use virtualbox-guest-additions package provide by Fedora.

I had install kernel-debug-devel but I need kernel-devel.
