That's a pity we could not examine what was actually happening.

Unfortunately there are many differences there.  The machine type
changes _something_ in qemu, there is different PCI(e) topology, and I
do not think I will be able to figure this out without the non-working
machine.

So if your current setup works for you right now I'd leave figuring out
the previous issue to others, if there is anyone wanting to figure out
if there is some libvirt issue.

Have a nice day
