Hi, Which version of qemu do you use ? I had this kind of issue when using an old version of qemu: upgrading qemu to 2.10 resolved my issue.
In qemu 2.5 (the default version with Ubuntu 16.04 in my case), the IO region is not mapped, which ends to this kind of error (the ressource0 is the IO region in the PCI bar).
