systemd-modules-load.service fails at boot and then it probably builds the
modules. After the system boots, systemd-modules-load.service has active
status and not failed. But the only way to get rid of Failed to start Load
Kernel Modules is by rebuilding initramfs via command dracut -v -f. This
error crops up everytime you install a new kernel irrespective of
VirtualBox's installation source.
