after a reboot to fix private address issue - the dash board stops working: ( see https://ask.openstack.org/en/question... )

[root@gibsonsg neutron]# grep -v "#" plugin.ini 
[ml2]
type_drivers = vxlan

tenant_network_types = vxlan

mechanism_drivers =openvswitch

[ml2_type_flat]

[ml2_type_vlan]

[ml2_type_gre]

[ml2_type_vxlan]
vni_ranges =10:100

local_ip=192.168.1.126
enable_tunneling=True
integration_bridge=br-int
tunnel_bridge=br-tun

vxlan_group =224.0.0.1

[securitygroup]
enable_security_group = True

Screen:

Something went wrong!

An unexpected error has occurred. Try refreshing the page. If that doesn't help, contact your local administrator.

The "Home" and " Help" choices doesn't work either

vxlan_group =224.0.0.1 placed in wrong section . Should be in [ml2_type_vxlan] NOT [ovs].

Does Neutron work from the command-line? Could you update the questions with the Horizon/httpd logs?

It appears if nuetron is down the dash board doesn't work ( you can't login ) .

SEEMS LIKE A HORRIBLE BUG TO ME

Please, be more concrete what doesn't work. I would guess
1. neutron-server doesn't run
2. No connect to dashbord
Have you tried
Restarting rabbitmq-server, neutron-server ?
Provide also
$ service httpd status -l
/var/log/neutron/server.log
/var/log/neutron/openvswitch-agent.log

The bottom line -- IF NEUTRON FAILS TO START ; YOU CAN'T LOGIN THE DASHBOARD
