Folks,
  I'm having an issue with loading kernel modules after a kernel update.  Specifically I'm having an issue with loading virtual box kernel modules.  After an update I sign the modules according to the information listed here

https://docs.fedoraproject.org/en-US/fedora/f33/system-administrators-guide/kernel-module-driver-configuration/Working_with_Kernel_Modules/

After signing the modules and verifying them via

modinfo <module> | grep "^sig"

I reboot the system.  After booting the system I run lsmod to check if the modules have been loaded and they have not.  I go check the modules again and I find they are no longer signed.

I resign the modules and rather than rebooting I run insmod to install them and this works.

Now I also have vmware installed on the system and I follow the exact same procedure to sign the vmware kernel modules and reboot the system and when I do an lsmod after rebooting the vmware modules are loaded.

I even tried rebuilding both the virtual box and vmware modules from source, resigned all the modules and rebooted and again only the vmware modules are loaded.  The virtual box modules no longer show they are signed.

Can anybody tell me why the virtual box modules are no longer signed after rebooting?

Any help is appreciated.

Paolo
