Bug description:
I am a beginner, trying to build a house.
Openstack Mitaka
Centos 7
host
controller 192.168.100.10 192.168.100.20
compute 192.168.200.10 192.168.200.20
==================================
neutron network
name IP
ext-net ext-subnet 192.168.200.0/24 (external network)
net200 net200-subnet 200.0.0.0/24 (internal network)
net100 net100-subnet 100.0.0.0/24 (internal network)
I created two nodes, the name is 'controller' and 'compute' . Is the
same name and server . Each node is a double network and Intranet .
When I attached floating IP cannot access nodes . Then remove nodes .
When I recreate the tip cannot be created .
Here is the error log
