Open Stack

I couldn't see anything wrong.
in my l3.filters:

[Filters]

# arping
arping: CommandFilter, arping, root

# l3_agent
sysctl: CommandFilter, sysctl, root
route: CommandFilter, route, root
radvd: CommandFilter, radvd, root

metadata_proxy: CommandFilter, neutron-ns-metadata-proxy, root
# If installed from source (say, by devstack), the prefix will be
# /usr/local instead of /usr/bin.
metadata_proxy_local: CommandFilter, 
/usr/local/bin/neutron-ns-metadata-proxy, root
# RHEL invocation of the metadata proxy will report 
/opt/stack/venvs/openstack/bin/python
kill_metadata: KillFilter, root, python, -9
