Currently, memory device (def->mems) part of cmd line is generated before any controller. In majority of cases it doesn't matter because neither of memory devices live on a bus that's created by an exposed controller (e.g. there's no DIMM controller, at least not exposed). Except for virtio-mem and virtio-pmem, which do have a PCI address. And if it so happens that the device goes onto non-default bus (pci.0) starting such guest fails, because the controller that creates the desired bus wasn't processed yet. QEMU processes arguments in order. For instance, if virtio-mem has address with bus='0x01' QEMU refuses to start with the following message: Bus 'pci.1' not found Similarly for virtio-pmem. I've successfully tested migration and changing the order does not affect migration stream.
