Description Paolo Bonzini 2012-11-16 05:37:59 EST
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.
