"mach-virt" just means "completely described by device tree with no knowledge hardcoded in the kernel about the platform". We don't currently have any PCI host controller which is: (a) for ARM (b) entirely device tree driven (c) supported by QEMU (d) with a decent Linux driver So mach-virt doesn't have PCI; it will use virtio-mmio, same as kvmtool for ARM does. -- PMM
