Right -- these devices are the PCIe controller that's used on the i.MX7 and i.MX6 SoCs, and they're automatically created when you use a machine type that uses one of those SoCs. The "virt" board doesn't use that PCIe controller, it uses the "generic PCIe bridge" TYPE_GPEX_HOST (and you automatically get a PCIe controller when you use the virt board). You can't change the PCIe controller type of a QEMU machine from the command line, you have to configure the guest to use the controller the machine type provides. thanks -- PMM
