I overcame the problem of getting a valid key-pair value.   I'm not sure exactly how it was fixed, but I found the rabbitmq server was down.  This was a result of a host name conflict. The /etc/hostname and /etc/hosts files must both have the same hostname.    I fixed that, and key-value pair now works.    I'm not sure if that was the reason, because of some funny behavior prior, and it didn't initially complain about this.  Suffice to say, I'm glad it's working!

Anyway, I'm doing the first tutorial, and I've run into an issue.  

Here is the tutorial:

I ran through the steps, and when I got to Step 5, it wanted me to select a "private network," however I only have a public network to select.

  Create demo_network under particular user belongs  to tenant "demo" ( whose login has been used )
  demo_network should have interface attached to router, created by same user ( ACTIVE State )
  and having external gateway to public.
  Then in dropdown menu will appear just created demo_network. If  you select it ( with correct DNS server
  been defined ) then VM supposed to be launched ( say CirrOS 3.4) will get Internet outbound connectivity.
  As soon as you assign floating IP from public pool VM will get inbound connectivity.

I'm running this thing to get myself started, so that I can learn Openstack.  So, I'm not sure why there is no private network, nor how I can create one.

Network may  be created via dashboard GUI right here . Maybe be created via Neutron CLI with corresponding credentials been sourced previously (# .  keystonerc_user )

Does anyone have any ideas on this?

Thanks!
