Need help setting up neutron networking
So, here's the goal. A 10 node cluster, each node will have a physical IP on 10.5.0.0/23. The virtual machines should receive private IPs of 10.50.0.0/16. Then I'll want a floating IP pool of 10.5.8.0/21.
I had this working (mostly) in Essex with nova, but I'm having a really difficult time translating this to Juno neutron. I feel like I'm setting up the networks properly, but the DHCP is not giving out private IPs to the instances, and floating IPs never get assigned to a virtual interface on the host (but are assigned in the dashboard), and so the virtual machines are not accessible from the outside.
I've been installing using packstack --allinone and setting up my interface using the instructions for "Neutron with existing external network". I've also removed the default networking info that packstack installs that's not valid in my network (as referenced by this question in these forums: https://ask.openstack.org/en/question... ). Below are the commands I've used to install the instance and create the networking. I'm completely stumped here, I don't understand why this isn't working. There are no errors in dhcp-agent.log, or in server.log.
Install
packstack --allinone --provision-all-in-one-ovs-bridge=n
vi /etc/sysconfig/network-scripts/ifcfg-br-ex
vi /etc/sysconfig/network-scripts/ifcfg-eth0
vi /etc/neutron/plugin
vi /etc/neutron/plugin.ini
service network restart

Please, post
ls -l /etc/neutron&& /etc/neutron/plugins/ml2/ml2_conf.ini as update 1 to your questionPlease , post
Ok, I updated the question with those updates, thanks in advance.
Creating private subnet you skipped DNS Server.
Maybe I skipped it and then added one in the dashboard, but I think there is an agent for that net:
Is that what you're looking for? Also shows up in the agent list
