... and it should also have figured it is prefetchable memory. Was pci
config space messed up somehow? What does 'lspci -v' say once you've
booted the machine with linux?
What qemu version you are running?
What kind of device is this?
Emulated? Code somewhere?
Or a real device passed through to the guest?
