    always set --no-hosts for dnsmasq
    
    Many network modes in nova-network disable reading host entries from
    /etc/hosts. This includes running vish-ha (multihost), or if you ever
    set a dns server. However if you don't do these things we continue to
    use /etc/hosts.
    
    It's not clear that this does anything other than create
    inconsistency. There is a long standing bug that exists around this
    because the impacts include exposing localhost as a dns entry on the
    network.
