As a theoretical question, maybe. But that's never going to
happen, so the practical answer is 'this will never work'.

Peter Maydell,
can I assume that It would be possible if there was the full emulation of the 
Lenovo hardware, including the all firmware blobs and Intell ME?

Regards,
Aleksey

In general, you can't run a UEFI firmware image from real hardware
on QEMU. The things the firmware will try to do are very low
level and it will assume that it's running on a Lenovo laptop,
which is not exactly the same hardware that QEMU provides.
Even if you figured out how to extract a binary blob from whatever
wrapper Lenovo puts it in for downloading, it would just crash
if you tried to run it in QEMU.

You should run a UEFI image that is compiled to know it is
running on QEMU, like the EDK2 one.

qemu running uefi problem

2023-03-12 Thread Ahlani Poacher 
Hello, sorry to bother you, I'm a qemu beginner. I want to use QEMU to
emulate Lenovo's UEFI firmware, but so far I have only found a tutorial for
QEMU to run EDK2 to implement UEFI. I would like to ask how to convert the
UEFI executable downloaded from Lenovo's official website to a QEMU
compliant format to emulate Lenovo UEFI using QEMU. I hope you can answer
my question, thank you.

best regards
