This appears to not work properly. I sent mail to qemu-devel asking for clarification/help: http://lists.nongnu.org/archive/html/qemu-devel/2012-10/msg02355.html So in the meantime I guess I need to pursue the "reattach the same tap device to a new bridge" idea as far as it will go, and save this patch for later :-( -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
