Description of problem: There are three problems in the packaging of qemu-bridge-helper. 1) No ACL is installed, so it doesn't work out of the box. 2) The helper is not installed suid root 3) The path used by the QEMU executable includes an unexpanded ${libexec} variable. Version-Release number of selected component (if applicable): 1.2.0-18.fc18 How reproducible: 100% Steps to Reproduce: 1. Install libvirt, ensure virbr0 is up. 2. Start qemu-kvm test.img -m 512 -net bridge,br=virbr0 -net nic Actual results: QEMU fails to launch the helper. If the ",helper=/usr/libexec/qemu-bridge-helper" option is added after "br=virbr0", it fails to grab the TAP device. Expected results: QEMU starts, "brctl show" includes the tap0 NIC into virbr0.
