Looking up Bugzilla, seems like it's needed to get Neutron networking
security groups working correctly, this is the bug

    https://bugzilla.redhat.com/show_bug.cgi?id=981144 -- need to set
    net.bridge.bridge-nf-call-iptables=1 for --allinone installation

which says

    For the single node deployment with "packstack --allinone",
    following kernel parms should be set so that the security group
    works correctly.
    
    net.bridge.bridge-nf-call-ip6tables = 1
    net.bridge.bridge-nf-call-iptables = 1
    net.bridge.bridge-nf-call-arptables = 1
