*** Bug 1389654 has been marked as a duplicate of this bug. *** That error normally will show up if you are trying to assign a PCI address to a device in the configuration for a arch/machinetype that doesn't support PCI. Can you attach the XML for the domain that you are trying to define? (I made the XML private because it contained a password :-) Although you haven't specified "arch" in your os <type> element, that *should* be filled in with the default (which matches the host's arch). In your case, arch should have been set to "x86_64", which would then cause libvirt to add a pci-root controller, so there would be PCI buses. For some reason that isn't happening. The only thing I can think of is that possibly the machinetype "pc" is being change into something that doesn't match the function qemuDomainMachineIsI440FX() (in src/qemu/qemu_domain.c), so libvirt doesn't recognize that it has a pci-root controller. We *might* get to the bottom of the problem if you attach the output of "virsh capabilities" so we can see what is the canonical machinetype for "pc" for /usr/libexec/qemu-kvm on your machine.
