patch rebased to RHEL-5 libvirt
This is the upstream patch newly rebased to the RHEL-5 libvirt-0.6.3. I built and tested, and it does now pass the test.

Created attachment 367379 [details] Upstream fix for this issue Description of problem: The bridge associated with a network created and started with virsh net-define and virsh-start is not actually enabled ("ip link set DEVICE up") if the host has no IP on that bridge. Version-Release number of selected component (if applicable): libvirt-0.6.3-20.1 How reproducible: Every time. Steps to Reproduce: 1. virsh net-define <(echo "<network><name>test_noip</name><uuid>9533aa79-1064-449d-8b43-1b873e5e52d4</uuid><bridge name='test_noip_br'/></network>") 2. virsh net-start test_noip 3. ip -o link show test_noip_br | grep -q UP && echo 'Pass' || echo 'Fail' Actual results: Above steps should emit 'Pass'. Expected results: Given test emits 'Fail'; bridge does not pass packets. Additional info: Fixed in upstream libvirt commit e978774ec67f4b062b1f65e5c76a13193a9430eb; patch (which applies cleanly except for the changelog entry) attached for reference.
