Re:‏ qemu running uefi problem

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,

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.
