The vexpress-a15 machine type does not support PCI. Therefore you cannot add PCI cards to it. If you want PCI, you'll need to use a different machine type. We usually recommend the "virt" machine if you don't care about the specifics of the guest machine (e.g. the common "I just want to run Linux" usecase). thanks -- PMM
