i´m still having problem with libvirt and pci passthrough, if i use more
then one pci card in the guest.

If i start qemu 0.10.5 manualy, i can use all of the pci devices in the
guest, here is the log: http://nopaste.info/610fa81fb5.html

If i use libvirt to start the guest and passthrough three pci device,
none of the device is usable in the guest:
What does /var/log/libvirt/qemu/vdr.log say?


The log says:

It looks like libvirt is doing its job correctly.

Try with managed='no' perhaps?


The same error messages with "managed='no' "
