Secure boot and VirtualBox Component Signing

VirtualBox requires the components to be signed and key to be enrolled with to work with Secureboot. To do so, first generate the keys using the command-

openssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -days 36500 -subj "/CN=Descriptive name/"

Above command will generate two files MOK.priv and MOK.der. To sign VirtualBox components execute the script sign-vboxmods.sh in the same folder where the MOK.* files have been generated. Once you have signed the components, you need to enroll the key (only once) as shown below-

sudo mokutil --import MOK.der

Now, reboot the machine, enrol the key from the manager screen and probe the component as shown below-

sudo modprobe vboxdrv

Kernel Upgrades and DKMS Key Issues

If you update your kernel, you need to make sure that all your DKMS modules are installed. Run build-dkms-modules.sh to fix one of these issues-
