If i'm not wrong error goes from: qemuBuildInterfaceCommandLine builds interface command line and before qemu started tries to add tap device to tc, but tap created later via qemu (in my case). I think that virNetDevBandwidthSet needs to be run after qemu started. -- Vasiliy Tolstov, e-mail: v.tolstov@xxxxxxxxx jabber: vase@xxxxxxxxx -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
