Here's the latest dmesg: http://pastebin.com/0ZSP31uf Lots and other dumps are available further up this thread. fwiw, I've somehow managed to get it to do something different. After passing though the soundcard, installing Ubuntu 10.10 on the VM and trying some of the other 14.x PCI devices I managed to really upset libvirt. After restarting it on the host server, I added 08:06.0, 1 and 2 again and got slightly further: [ 5805.521230] firewire_ohci: Removed fw-ohci device.

I guess that means I have to add rw access for sys_rawio? That's all for tonight, probably won't get any more time on this until Wednesday 19:00 GMT.
