[libvirt] Problem with libvirt and pci passthrough
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? Cheers, Mark.

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

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

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.
