The trick here is that we name the bus the devices will be attached to by the pxb id. - When we have the bridge -> the pxb id will be used for the secondary bus - when don't have the bridge -> the pxb id wil be used for the root bus. Both times the command line remains -device pxb,id=my_root -device e1000,bus=my_rootWhat would you lose? Hotplug?
Without the bridge? Yes. However the user can add it manually the pci-bridge and have it anyway. I wanted to get rid of the internal pci-bridge as a default, and this is why pxb and pxb-pcie are he same device now (except bus type)
