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.
