Hi,

i tried your patches and now it works, no segfault anymore.

But the other problem is, that i tried a lot of pci device and passed 
them through in the guest, but none
of them were usable in the guest.

I tried three WLAN-PCI-cards, installed the driver in the guest, but i 
had no success to get a signal from my WLAN-router.
In the host, the cards works well, with same driver and same kernel.

The same problem do i have with my dvb-cards, in the host they works 
very well, i can create a channels.conf with scanning the transponders,
but in the guest, i dont get any signal.

I think, its more a problem of qemu then libvirt.
