Public bug reported:
Main steps:
1 create 2 external networks each with a different subnet with neutron CLI
commands, there is no error info from CLI.
e.g. neutron net-create --router:external=True --provider:physical_network
provider100 --provider:network_type flat provider100
2 create 2 routers connected each of the external net, there is no error info
from CLI.
3 create 1 floating ip from one of the external network, no error info from CLI.
4 create 1 private network, and try creating a vm connected to the private
network.
there is no response with the command: nova boot xxx.
We can see errors from screen, seems neutron CLI needs more checking when
creating more external networks.
