Hi,
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:
http://nopaste.info/ccfbfcf9a0.html
Is there any limitation in libvirt?
Greetings
Mirko

What does /var/log/libvirt/qemu/vdr.log say?

It looks like libvirt is doing its job correctly.
Try with managed='no' perhaps?

Ok, i gave up. There seems to be no chance to use libvirt and pci
passthrough with more then one pci device.
Now i start qemu with a bash script and that works fine till now.
