Yes.

OK.

This is the change btw, the 64-bit mmio window is moved.
Apparently we got 48 bits guest physical address space.

And here things go wrong. The size is /way/ off (bar 4 is 16k).
Can you try to reduce the guest physical address space?
Try 46 instead of 48 first, if that doesn't help try
smaller values.
qemu command line:
-cpu host,host-phys-bits-limit=46
libvirt xml:
<cpu ...>
<maxphysaddr mode='emulate' bits='46'/>
</cpu>
take care,
