when trying to install a recent(!) image of Win11 in KVM in a machine with
either paththrough of TPM or virtualized TPM the process stalls in "firmware
Tiano Core". 

There is no error message, the iso simply stalls when loading the Tiano Core
firmware. 

I tried also to download another image, I checked the checksum. But still, even
if selecting correctly the iso, no luck.
