for Qemu one has to provide the UEFI firmware. We have built the UEFI
firmware based on the Tianocore project and ship it with Genode, which
worked well with the Qemu version we are using (for me personally 2.4.x
- 2.9.x).

I presume, that you need for your latest Qemu version potentially a
newer UEFI build. In tool/boot/README we documented what we did to build
the UEFI firmware in the past.

So, either try to use some older Qemu version first or try to re-build
the UEFI firmware as described by the Tianocore project.

Good luck,
