Hello Paolo,

Thanks a lot for your patch.

I tested it with the RC4 of kernel 6.13 today but unfortunately it 
doesn't solve the KVM HV issue. The guest system doesn't boot and I 
can't see any error messages. (console=ttyS0)

But do you see anything on the host dmesg (without and with the patch), 
for example a WARN?

Also you might try edebc0a1b7ab5ff19b4f5cd011c93196fc34b3e4 + the patch, 
to see if there are two bugs.
