I have packstack installed with neutron on a seperate system.
If the neutron system reboots I find that the networking is broken.
I have the feeling the some iptables data is getting lost on reboot.
So are there iptables rules that get setup by neutron dynamically? Are these rules saved to be reapplied on reboot?
neutron is responsible of iptables
[securitygroup] firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
and make sure nova have the firewall driver Noopfirewall which will make neutron responsible of iptables. But I don't belive this is your problem.
If you installed Juno via packstack --allinone on a single box, the most common issue - after reboot br-ex doesn't come
up with IP address.
Add to /etc/rc.d/rc.local :
ifdown br-ex ;
ifup br-ex ;
service network restart ;
The interface seems to come up correctly. I am not doing an allinone install. I am actually using 4 virtual servers, 1 control, 2 compute and 1 neutron.
The real answer is that this computer hates me and is out to make me look like an idiot.
I have not been able to recreate the problem. I did find that boot order is important in multi node installs and that may have been my problem but I can't be sure at this point.
Thanks to those who tried to help.

Check does br-ex have IP after reboot ? What OS are you running ?
br-ex does seem to come up. I am running Centos7
The problem has not come back after the latest reboot so it gves me an idea.
