5 In qdev, each device has a parent bus.  Some devices provide one or
10 where this address can be configured, devices provide a bus-specific

34 of which can have up to two devices, and each device is a guest part,
41 The old ways to define block devices define host and guest part
70 * serial goes into DEV-OPTS, for devices supporting serial numbers.
71   For other devices, it goes nowhere.
95   As for all PCI devices, you can add bus=PCI-BUS,addr=DEVFN to
111   "Default Devices".
122   As for all PCI devices, you can add bus=PCI-BUS,addr=DEVFN to
128 For USB devices, the old way was actually different:
149 === Character Devices ===
153 The old ways to define character devices define host and guest part
231 QEMU uses LEGACY-CHARDEV syntax not just to set up guest devices, but
236 === Network Devices ===
238 Host and guest part of network devices have always been separate.
260 For PCI devices, you can add bus=PCI-BUS,addr=DEVFN to control the PCI
268 except for virtio-net-pci (model=virtio).  With -device, only devices
271 Not all devices are available with -device at this time.  All PCI
272 devices and ne2k_isa are.
274 Some PCI devices aren't available with -net nic, e.g. i82558a.
276 === Graphics Devices ===
278 Host and guest part of graphics devices have always been separate.

310 === Audio Devices ===
312 Host and guest part of audio devices have always been separate.
314 The old way to define guest audio devices is -soundhw C1,...

354 === Watchdog Devices ===
356 Host and guest part of watchdog devices have always been separate.
359 The new way is -device DEVNAME.  For PCI devices, you can add
364 QEMU supports assigning host PCI devices (qemu-kvm only at this time)
365 and host USB devices.  PCI devices can only be assigned with -device:
