I also made the EFI firmware file available to Virtualbox. I created a vbox file and tested it on another Linux system. However, when using this vbox file on sculpt, I noticed that vbox does not respect the '<Firmware type="EFI"/>', i.e. neither my boot manager nor the UEFI shell appears. I had a look in the Genode repository and noticed that there is a vbox patch that removes (ifdef 0) the Nvram initialisation which is supposed to happen if the firmware type is EFI.

It is not clear, why this happened. Since nobody asked for this feature,
it just went unnoticed. Fell free to enable it and see where you get. At
least no blockers are known.
