Hi,
I have tried that too and that did not help either (i.e adding the format
type=gpt)
The output you requested

Could you please also attach the output of:
qemu-img info --backing-chain '/var/virt/WINDOWS/WIN11'

cache="unsafe"/>

In the definition I don't see anything that would hint that anything
with the disk config is broken, for qcow2 volumes we do auto-detection
of backing images, thus the request for the output of the command above.
