Okay, one more try! ;)
Using -nodefaults is required to have full control over
the virtual hardware: when it's specified, QEMU will
populate the board with only the builtin peripherals,
such as the PL011 UART, plus a PCI Express Root Bus; the
user will then have to explicitly add further devices.
The PCI Express Root Bus shows up in the guest as:
00:00.0 Host bridge
