  Hi,

Hmm, it's not, the ac97 emulation doesn't use the default qemu subsystem
id for some reason.  Here is the entry:

[root@fedora ~]# lspci -vns6
00:06.0 0401: 8086:2415 (rev 01)
        Subsystem: 8086:0000
        Physical Slot: 6
        Flags: bus master, medium devsel, latency 0, IRQ 10
        I/O ports at c000 [size=1K]
        I/O ports at c400 [size=256]
        Kernel driver in use: Intel ICH
        Kernel modules: snd-intel8x0

I guess that should be fixed.  8086:0000 isn't valid anyway and I doubt
it serves any useful purpose other than avoiding a guest complaining
about the subsystem id being unset.

/me goes preparing a patch.

cheers,
  Gerd
