Hello Don!

Some additional information about the bridge device 00:14.4 itself
(both legacy PCI cards are behind this bridge device - it's an output with both legacy devices plugged in):

00:14.4 PCI bridge: ATI Technologies Inc SBx00 PCI to PCI Bridge (rev 40) (prog-if 01 [Subtractive decode])
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop+ ParErr- Stepping- SERR- FastB2B- DisINTx-
        Status: Cap- 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
        Latency: 64
        Bus: primary=00, secondary=05, subordinate=05, sec-latency=64
        I/O behind bridge: 0000a000-0000afff
        Memory behind bridge: fda00000-fdafffff
        Prefetchable memory behind bridge: fd900000-fd9fffff

                PriDiscTmr- SecDiscTmr- DiscTmrStat- DiscTmrSERREn-

If the bridge is put to the VM too, libvirt exits with the following error:

error: internal error Unable to reset PCI device 0000:00:14.4: no FLR, PM reset or bus reset available


The wlan device looks like this:

05:07.0 Network controller: RaLink RT2800 802.11n PCI
        Subsystem: Linksys Device 0067

        Latency: 32 (500ns min, 1000ns max), Cache Line Size: 64 bytes
        Interrupt: pin A routed to IRQ 21

Thank you for your advice,
kind regards,
Andreas Hartmann
