Folks, Today I spotted [1]. It turns out Neutron and Nova might be racing trying to set up the bridge to provide VM with connectivity/dhcp. In the observed failure mode, os-vif fails in [2]. I suppose we might need to protect the bridge creation and make it handle the potential exception. We would need a similar fix for Neutron in [3]. That said, knowing there is a looming deadline [4], I'd invite folks to keep an eye on the bug. Many thanks, Armando [1] https://bugs.launchpad.net/neutron/+bug/1617447 [2] https://github.com/openstack/os-vif/blob/master/vif_plug_linux_bridge/linux_net.py#L125 [3] http://git.openstack.org/cgit/openstack/neutron/tree/neutron/agent/linux/bridge_lib.py#n58 [4] http://lists.openstack.org/pipermail/openstack-dev/2016-August/102339.html -------------- next part -------------- An HTML attachment was scrubbed...
