You might not want to (or be able to) disable UEFI Secure Boot. In this case you can selfsign the evdi module.

Øyvind Stegard wrote a very clear and helpful guide for signing VirtualBox modules. You only have to replace step 5 by this:

# nano /root/module-signing/sign-evdi-module.sh

#!/bin/bash

for modfile in $(dirname $(modinfo -n evdi))/*.ko; do
  echo "Signing $modfile"
  /usr/src/linux-headers-$(uname -r)/scripts/sign-file sha256 \
                                /root/module-signing/MOK.priv \
                                /root/module-signing/MOK.der "$modfile"
done

# chmod 700 /root/module-signing/sign-evdi-module.sh

And you can ignore step 7.
