[Bug 1662789] [NEW] qlalchemy.exc.OperationalError

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

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

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
