Its there already:
(qemu) info pci
Bus 0, device 0, function 0:
Host bridge: PCI device 8086:1237
Bus 0, device 1, function 0:
ISA bridge: PCI device 8086:7000
Bus 0, device 1, function 1:
IDE controller: PCI device 8086:7010
BAR4: I/O at 0xc000 [0xc00f].
Bus 0, device 1, function 3:
Bridge: PCI device 8086:7113
IRQ 9.
Bus 0, device 2, function 0:
VGA controller: PCI device 1013:00b8
BAR0: 32 bit memory at 0xf0000000 [0xf1ffffff].
BAR1: 32 bit memory at 0xf2000000 [0xf2000fff].
Bus 0, device 3, function 0:
Ethernet controller: PCI device 10ec:8139
IRQ 11.
BAR0: I/O at 0xc100 [0xc1ff].
BAR1: 32 bit memory at 0xf2001000 [0xf20010ff].
And block,network:
(qemu) info block
ide0-hd0: type=hd removable=0 file=/root/images/marcelo5.img ro=0 drv=raw
ide1-cd0: type=cdrom removable=1 locked=0 [not inserted]
floppy0: type=floppy removable=1 locked=0 [not inserted]
sd0: type=floppy removable=1 locked=0 [not inserted]
scsi0-hd0: type=hd removable=0 file=/tmp/bigfile ro=0 drv=raw
scsi0-hd1: type=hd removable=0 file=/tmp/bigfile.2 ro=0 drv=raw
(qemu) info network
VLAN 0 devices:
tap: ifname=tap0 setup_script=qemu-ifup-tap0
rtl8139 pci macaddr=52:54:00:12:34:56
Perhaps reporting the <bus,slot> pair for PCI devices on block and
network info provides the necessary information that you need Dan?
Oh, and unit,bus,media for block too.
